Green plants absorb light energy using chlorophyll in their leaves. They use it to react carbon dioxide with water to make a sugar called glucose. The glucose is used in respiration‚ or converted into starch and stored. Oxygen is produced as a by-product. This process is called photosynthesis. Temperature‚ carbon dioxide concentration and light intensity are factors that can limit the rate of photosynthesis. Plants also need mineral ions‚ including nitrate and magnesium‚ for healthy growth. They

The offspring will be plants that are identical to the parent plant. Cloning preserves the character of your favorite plant. Cloning can make an ocean of green out of a single plant‚ so it is a powerful tool for growing large crops‚ and will fill a closet quickly with your favorite genetics. When you find the plant you want to be your "buddy" for the rest of your

(Cacurbita moschata)‚ beet (Beta vulgaris)‚ and pepper (Capsicum annuum) are all dicot plants‚ which mean that they have two seed leaves inside the seed coat. When they are placed in an environment and are watered with solutions of different acidic and alkaline levels‚ the root growth during germination is affected. The purpose of this experiment was to observe what type of substance‚ acidic or basic‚ increases the growth of roots during the germination process of Cacurbita moschata‚ Beta vulgaris‚ and

INSECTIVOROUS PLANTS An insectivorous plant‚ also called a carnivorous plant‚ captures prey items‚ such as insects‚ spiders‚ crustaceans‚ mites‚ and protozoans‚ as a nitrogen source. Many insectivorous species live in freshwater bogs‚ where nitrogen is not present in available form‚ because the pH of the water is extremely acid. The forms of entrapment by these types of plants are modified leaves. Five basic trapping mechanisms are found in carnivorous plants. 1. Pitfall traps (pitcher plants) trap prey
