Question: Name three things that plants need from their environment for photosynthesis?

Photosynthesis is the process by which plants use light energy to convert carbon dioxide and water into sugars and oxygen. This is essential for the survival of plants and the animals that depend on them. But what are the three things that plants need from their environment for photosynthesis to occur?

The first thing that plants need is light. Light provides the energy for the chemical reactions that take place in the chloroplasts, the organelles where photosynthesis happens. Plants can use different wavelengths of light, but they mostly absorb red and blue light and reflect green light. That's why most plants appear green to our eyes.

The second thing that plants need is carbon dioxide. Carbon dioxide is a gas that makes up about 0.04% of the atmosphere. Plants take in carbon dioxide through tiny pores called stomata on the surface of their leaves. Carbon dioxide is then combined with water to form glucose, a simple sugar that plants use as food.

The third thing that plants need is water. Water is absorbed by the roots of the plant from the soil and transported to the leaves through a system of tubes called xylem. Water is also involved in the chemical reactions of photosynthesis, as it is split into hydrogen and oxygen atoms. The oxygen atoms are released as a by-product, while the hydrogen atoms are used to make glucose.

These are the three things that plants need from their environment for photosynthesis: light, carbon dioxide and water. Without any of these, photosynthesis would not be possible and plants would not be able to grow and produce oxygen for us to breathe.
