Word Description
Acidity How acidic or “sour” a soil’s pH is.
Air handler The indoor unit that moves the air through the heating/cooling system.
Air Leakage (AL) a rating that expresses the amount of air infiltration through cracks in the whole window
Air Plants A plant that does not root in soil. It derives moisture and nutrients from the air
Algae White, red, pink or grey circular patches that look like they are painted on the trunk of trees and shrubs. These are harmless and add color and interest to your landscape.
Alkalinity How alkaline or “sweet” a soil’s pH is.
Aluminum/foil tape Specialty tape with an acrylic-based adhesive that performs consistently under extreme temperatures.
Aphids are soft bodied pear-shaped insects that suck juices from plants. They generally are less than 1/8 inch long and usually green in color but many are black, brown, pink, yellow, blue, or white.
Asthma Asthma attacks all age groups but often starts in childhood. It is a disease characterized by recurrent attacks of breathlessness and wheezing, which vary in severity and frequency from person to person. In an individual, they may occur from hour to hour and day to day. This condition is due to inflammation of the air passages in the lungs and affects the sensitivity of the nerve endings in the airways so they become easily irritated. In an attack, the lining of the passages swell causing the airways to narrow; reducing the flow of air in and out of the lungs.
Bacillus thuringiensis Commonly called B.T., (Bt) occurs naturally in the soil and on plants. Different varieties of this bacterium produce a crystal protein that is toxic to specific groups of insects. Bt has been available in North America as a commercial microbial insecticide since the 1960s and is sold under various trade names. These products have an excellent safety record and can be used on crops until close to the day of harvest. Bt can be applied using conventional spray equipment but, because the bacteria must be eaten to be effective, good spray coverage is essential.
Baking powder A leavening agent used in cookies, quick breads and other baked goods to produce expansion of a batter. It is made of baking soda and cream of tartar or another acid powder. It is almost always double action. This means it releases carbon dioxide when mixed with liquid, and releases it again when exposed to heat. Make sure, when following a recipe, that you don't confuse it with baking SODA, because your recipe will be ruined. You can make your own baking powder, which will be single action, by combining baking soda with cream of tartar.
Ballast The device that stabilizes the electric current for stable operation of a bulb. Depending on the bulb it is either attached to the bulb (enerally as in compact florescent bulbs) of be part of the fixture (as in pin-based and fluorescent tubes). Units with seperate ballasts and bulbs re preferable because ballasts last much longer than bulbs
Bedding Plants Plants that are seasonal, used for their colorful blooms or interesting foliage.
Blanching To plunge foods into boiling water for a few seconds or a few minutes, then remove and place in ice water.
Blood Glucose The main sugar (in the form of glucose) that the body makes from food. Cells cannot use glucose for fuel without the help of insulin. The blood sugar level in humans is normally 60 to 100 milligrams per 100 milliliters of blood; it rises after a meal to as much as 150 milligrams per 100 milliliter of blood, but this may vary.
Brown sugar Brown sugar consists of sugar crystals coated in a molasses syrup with natural flavor and color. Many sugar refiners produce brown sugar by boiling a special molasses syrup until brown sugar crystals form. A centrifuge spins the crystals dry. Some of the syrup remains giving the sugar its brown color and molasses flavor. Other manufacturers produce brown sugar by blending a special molasses syrup with white sugar crystals. Dark brown sugar has more color and a stronger molasses flavor than light brown sugar. Lighter types are generally used in baking and making butterscotch, condiments and glazes. Dark brown sugar has a rich flavor that is good for gingerbread, mincemeat, baked beans, plum pudding and other full flavored foods.
Budded A grafted tree where the scion is a small piece of bark or wood containing a single bud.
Butter A soft yellowish or whitish emulsion of butterfat, water, air, and sometimes salt, churned from milk or cream and processed for use in cooking and as a food.
Calcium a mineral that is abundant in water and all living organisms.
Calorie A calorie is a unit of energy. Human beings need energy to survive -- to breathe, move, pump blood -- and we get this energy from food. The number of calories in a food is a measure of how much potential energy is in that food. A gram of carbohydrates has 4 calories, a gram of protein has 4 calories and a gram of fat has 9 calories. Foods are a combination of these three building blocks. So if you know how many carbohydrates, fats and proteins are in any given food, you know how many calories, or how much energy, that food contains.
Carbohydrate Carbohydrates are a type of food that have the job of providing all the cells in the body with the energy they need. When carbohydrates are consumed, the body turns them into glucose, a simple sugar, which provides sufficient energy for everyday tasks and physical activity. There are two types of carbohydrates: Simple and complex. Simple carbohydrates are found in fruits and are easily digested by the body. They are also often found in processed foods and anything with refined sugar added. Complex carbohydrates are found in nearly all plant-based foods, and usually take longer for the body to digest. In other words, they remain in the stomach longer. They are most commonly found in bread products, cereals, pasta, rice, and certain vegetables.
Cardiovascular exercise The ability of the body to sustain an activity for an extended period of time. Cardiovascular fitness is the ability of the lungs to provide oxygen to the blood and the heart to transport the oxygenated blood to the cells of the body.
CCT Correlated Color Temperature, a measure of the color appearance of a light source; CCT is measured in degrees Kelvin (K) the absolute temperature scale; white light products comonly range from "warm white" (2700K) to "cool white" (5000K)
CEU continuing education units
CFL Compact Florescent Lamp (lamp is the lighting industry's term for bulb)
Cholesterol A soft, waxy substance made by the body and found in animal products that we consume. Foods containing cholesterol include meat, fish, poultry, eggs and dairy products. Cholesterol travels in the blood as two compounds: low-density lipoproteins (LDL) and high-density lipoproteins (HDL). Cholesterol from food has not been shown to raise blood cholesterol levels. Rather, is is saturated fat in the diet that primarily raises blood cholesterol levels.
Chrysalis is the 3rd stage of a butterfly’s life. This form is the change from a caterpillar to a butterfly. This is also called the pupa stage.
Composting the biological decomposition of organic wastes. It turns ordinary kitchen and yard trimmings into what some call black gold. It happens naturally in the forests as leaves and other organic wastes decompose. It can be done in a controlled manner in your back yard.

Crown Top of the pineapple where the leaves emerge from the fruit.
Crown Rot Crown Rot is caused by the Phytophthora fungus, which attacks the roots and, most notably, the crown of African Violets. African Violets are most susceptible to Crown Rot when allowed to sit in soil that is heavy and soggy. In almost all cases, Crown Rot is fatal. The best control for Crown Rot is prevention.
Cultivar A cultivated variety; does not occur naturally.
Cultural practices Maintenance practices of a lawn including watering, fertilizing, mowing, and pesticide applications.
Daily Value DV, a term on food labels based on the RDA (Recommended Dietary Allowance) designed to help consumers use food label information to plan a healthy diet. The Daily Value serves as a basis for declaring on the label the percent of the DV for each nutrient that a serving of the food provides. For example, the Daily Value for fat, based on a 2,000-calorie diet, is 65 grams (g). A food that has 13 g of fat per serving would state on the label that the "percent Daily Value" for fat is 20 percent. That is because 13 grams represents 20% of 65 grams. The DV also provides a basis for thresholds that define descriptive words for nutrient content, called descriptors, such as "high fiber" and "low fat." For example, the descriptor "high fiber" can be used if a serving of food provides 20 percent or more of the Daily Value for fiber-- that is, 5 g or more.
DASH diet eating plan This is the name of a clinical study that tested the effects of nutrients in food on blood pressure. Study results indicated that you can reduce high blood pressure by following an eating plan that emphasizes fruits, vegetables, fat-free or low-fat milk and milk products, and is low in saturated fat, total fat, and cholesterol.
Dehydration: Excessive loss of body water.
Diabetes A condition caused by the body’s inability to use insulin to process the glucose (sugar) in the blood properly and so the level of glucose in the blood is too high for good health. It can be caused by too little insulin (a chemical produced by the pancreas to regulate blood sugar), resistance to insulin, or both.
Diabetes risk factor: A life style or life situation that increases a person's chances of developing a disease.
Diabetes symptoms Many people have no signs or symptoms. Symptoms can also be so mild that you might not even notice them. Some people have symptoms but do not suspect diabetes. Symptoms include increased thirst, increased hunger, fatigue, increased urination, especially at night, weight loss, blurred vision or sores that do not heal. Many people do not find out they have the disease until they have diabetes complications, such as blurry vision or heart trouble. If you find out early that you have diabetes, then you can get treatment to prevent damage to the body.

Egg The ovoid, hard-shelled reproductive body produced by a bird, consisting principally of a yolk and albumen egg white). It is a good source of protein, iron, sulfur and vitamins A, B, D and E but also relatively high in cholesterol
Egg white The common name for the clear liquid (also called the albumen) contained within an egg. It is the cytoplasm of the egg, which until fertilization is a single cell (including the yolk). It consists mainly of about 15% proteins dissolved in water. Its primary natural purpose is to protect the egg yolk and provide additional nutrition for the growth of the embryo, as it is rich in proteins and is of high nutritional value. Unlike the egg yolk, it contains a negligible amount of fat.
Egg yolk The part of an egg which serves as the food source for the developing embryo inside. The egg yolk is suspended in the egg white (known more formally as albumen or ovalbumin) by one or two spiral bands of tissue called the chalazae. As a food, egg yolks are a major source of vitamins and minerals. They contain all of the egg's fat and cholesterol, and almost half of the protein.

Groundcover A ground cover is any low-growing plant that can be used to cover an area in the landscape.
Harvested the gathering of a ripened crop.
HDL cholesterol “High-density lipoprotein” is one of the classes of lipoproteins that carry cholesterol in the blood. HDL is considered to be beneficial because it removes excess cholesterol from the blood and disposes of it. Hence HDL cholesterol is often termed "good" cholesterol.
Herbaceous Not woody; having no persistent woody stems above ground
High blood cholesterol Too much cholesterol in the blood, caused by eating foods high in saturated and trans fat, can increase your risk of heart disease. Cholesterol can build up on the walls of your arteries. This buildup of cholesterol is called plaque. Over time, plaque can cause narrowing of the arteries. This is called atherosclerosis (ath-er-o-skler-O-sis), or hardening of the arteries.

Insulin Insulin is a hormone produced by the beta cells of the pancreas which permits glucose from the blood to enter the body’s cells and helps the body use glucose for energy. Insulin controls the amount of glucose in the blood. People who are type 1 diabetic must use manufactured insulin, usually in an injectable form, to replace the natural insulin that is no longer produced by their pancreas. People with type 2 diabetes sometimes need to use insulin when their cells become resistant to the insulin that their pancreas makes naturally and oral medications are no longer working.

Red Meat Red meat in culinary terminology refers to meat which is red-colored when raw, while in nutritional terminology, it refers to meat from mammals. In nutrition, "red meat" is synonymous with "mammal meat." The term is often considered misleading, as not all mammal meat appears red, and some non-mammal meat can be red. Red meat does not refer to how well a piece of meat is cooked or its coloration after cooking. A steak or hamburger is a red meat whether it is served rare, or cooked until it is well-done; pork is also red, though it turns to a whitish color when cooked. According to the USDA all meats obtained from "livestock" are "red meats" because they contain more myoglobin (an iron-containing pigment in muscle cells that holds and stores oxygen) than chicken or fish.
Refined grains In contrast to whole grains, refined grains refers to grain products consisting of grains or grain flours that have been significantly modified from their natural composition. The modification process generally involves the mechanical removal of 2 of the 3 major parts of the grain: the bran and germ, either through grinding or selective sifting. Further refining includes mixing, bleaching, and brominating; additionally, thiamin, riboflavin, niacin, and iron are often added back in to nutritionally enrich the product. Because the added nutrients represent a fraction of the nutrients removed, refined grains are considered nutritionally inferior to whole grains.

Thrips Small ( 2.6 mm -3.6 mm) brownish-black insects that suck juices from leaves and flowers.
Trans fat Trans fat (also known as trans fatty acids) is mostly man-made form of fat. It is a specific type of fat formed when liquid oils are made into solid fats like shortening and hard margarine by food manufacturers. It is made by adding hydrogen to vegetable oil -- a process called hydrogenation. Hydrogenation increases the shelf life and flavor stability of foods containing these fats. Trans fat behaves like saturated fat by raising LDL or "bad" cholesterol that increases your risk of coronary heart disease and lowering HDL or “good” cholesterol in the blood.

Whole grain Whole grains are cereal grains which retain the bran and germ as well as the endosperm which are the 3 major parts of the grain. Iin contrast, refined grains retain only the endosperm. The whole truth is if the label doesn't say "100% whole grain," check the ingredient list to see if the food contains any refined grains or flour. Dead giveaways are enriched or unbleached wheat flour, semolina flour, durum flour, and rice flour. Enriched grains: A term usually applied to flour that, after the milling has stripped it of the germ and the bran and other nutritious elements, has niacin, riboflavin and thiamin added back into it. U.S. law requires that flours not containing wheat germ must have these nutrients replenished.
