Outline any 4 requirements of photosynthesis?

1. Light: Photosynthesis requires light as a source of energy. Plants use sunlight to convert carbon dioxide and water into glucose and oxygen.

2. Carbon dioxide: Plants take in carbon dioxide from the atmosphere through tiny pores called stomata on their leaves. Carbon dioxide is essential for the process of photosynthesis to occur.

3. Water: Plants absorb water from the soil through their roots. Water is a crucial component of photosynthesis as it provides hydrogen atoms needed to form glucose during the process.

4. Chlorophyll: Chlorophyll is a green pigment found in the chloroplasts of plant cells. It is responsible for capturing light energy and converting it into chemical energy during photosynthesis. Without chlorophyll, plants would not be able to carry out photosynthesis.

1. Chlorophyll: A green pigment that absorbs sunlight.
2. Water: Water is used to split into hydrogen and oxygen atoms.
3. Carbon dioxide: Carbon dioxide is used to combine with hydrogen to form glucose.
4. Light: Light energy is used to split water and combine hydrogen and carbon dioxide to form glucose.
