DENDROLOGY

Detailed explanation-1: -The effect of light intensity on photosynthesis can be investigated in water plants. Use Cabomba or Elodea, which are sold in aquarium shops. The plants will release bubbles of oxygen-a product of photosynthesis-which can be counted.

Detailed explanation-2: -Plants need light energy to make the chemical energy needed to create carbohydrates. Increasing the light intensity will boost the speed of photosynthesis. However, at high light intensities the rate becomes constant. Place a pond weed Elodea upside in a test tube containing water.

Detailed explanation-3: -As you rise from low light intensity to higher light intensity, the rate of photosynthesis will increase because there is more light available to drive the reactions of photosynthesis.

Detailed explanation-4: -Like other green plants, pond weed can make sugar from carbon dioxide and water. When this happens, oxygen is also made. This oxygen comes out of the plant and can be seen as bubbles in the water around the pond weed.

Detailed explanation-5: -Introduction. Egeria densa, also known as Elodea densa because of its previously incorrect classification in the Elodea genus, is the most popular aquatic plant used to teach photosynthesis in the classroom.
