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.
Plants require photosynthesis to make their own food (glucose) from water, carbon dioxide, and sunlight. They use a process called cellular respiration to break the glucose do â¦ wn into energy that the plant can use.Animals require the food and oxygen produced by photosynthesis for cellular respiration themselves.Plants, on the other hand, need animals' carbon dioxide in order to photosynthesize. Therefore, all life on Earth depends on photosynthesis. 1 person found this useful.. Photosynthesis is used to produce food from light, this is the most basic foundation of almost all food and life cycles on earth (primary producers). 2. Photosynthesis help â¦ s moderate the carbon dioxide levels of the planet.
