25 POINTS- I really need this asap Plants perform photosynthesis to create their own food source and use cellular respiration to unlock the energy from that food. In 3-5 sentences, argue which one of these two processes is used at certain times of day by plants. Specifically, which process is used during bright daylight hours, which process is used at night, and which process is used during early morning and late evening low-light hours? Why do you think this is the case?

What is photosynthesis?

Photosynthesis is a chemical process through which plants produce glucose and oxygen from carbon dioxide and water, using only light as a source of energy.

Process of photosynthesis

1. Chlorophyll absorbs the sun's energy.

2. It is this energy that is used to split water molecules into hydrogen and oxygen.

3. Xylem which is found in the stem, allows water to go up the roots and into the plants.

4. Carbon dioxide enters the plant through the stomata, which are pores that allow for the exchange of gases

5. Carbon dioxide and water reach the chloroplast

6. Water and carbon dioxide are used to form glucose and oxygen for plants.

7. Glucose is converted into a starch and stored for food

How does a plant release oxygen from photosynthesis?

They release CO2 (just like us, when we breathe). But, when plants are photosynthesizing, they release more O2 during photosynthesis than they will consume in respiration. They release the oxygen through the same pores (stomata) that allow the CO2 to enter their leaf cells.
