Answer:
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.
