Why does the plant need to do Photosynthesis?

Answer 1

Plants need photosynthesis in the same way that you need to eat. They convert the energy of the sun into glucose using water and carbon dioxide. They release oxygen, which you need like they need carbon dioxide. They use the glucose to grow. When we eat plants, we eat them for the glucose because we convert glucose into ATP, which is the energy molecule. We use ATP constantly to function, which is why we have to regularly consume food. That's why you eat your green vegetables. Plants that use photosynthesis are green because they absorb every color of light from the sun except for green, which they reflect because green light isn't efficient.

Yeah, whut he said.

Answer 2

Plants need to do photosynthesis for them to live and produce their own food...

Without photosynthesis, plants will not exist in our global society and much more, the human race will not exist.

Answer 3

Plants need photosynthesis for energy. They cannot directly live on the energy from the sun. It is absorbed by specific pigments in the chloroplasts (found in green plant parts) and via photosynthesis stored as starch. This starch is later used as an energy reserve. Hence the food chain starts.

Answer 4

They need photosynthesis to make food.

Sunlight -> to leaf -> to chlorophyll in the leaf -> make food for the plant to survive.

Answer 5

It is simply so they can get food!!
