The students will learn that: 1) the variables of light intensity, temperature, carbon dioxide, light quality all influence the rate of photosynthesis. 2) photosynthesis requires carbon dioxide to furnish the carbon required to make glucose.This carbon dioxide will be supplied by sodium bicarbonate dissolved in the water with the plant leaf disks.he students will learn that: 1) the variables of light intensity, temperature, carbon dioxide, light quality all influence the rate of photosynthesis. 2) photosynthesis requires carbon dioxide to furnish the carbon required to make glucose.
Photosynthesis Photosynthesis is the process by which plants, some bacteria and some protistans use the energy from sunlight to produce glucose from carbon dioxide and water. This glucose can be converted into pyruvate which releases adenosine triphosphate (ATP) by cellular respiration. Oxygen is also formed.Photosynthesis may be summarised by the word equation: carbon dioxide + water glucose + oxygen The conversion of usable sunlight energy into chemical energy is associated with the action of the green pigment chlorophyll.hotosynthesis Photosynthesis is the process by which plants, some bacteria and some protistans use the energy from sunlight to produce glucose from carbon dioxide and water.
