Photosynthesis is the process by which

Carbon dioxide from the air passes through small pores holes in the leaves. Photosynthesis is the process by which plants make their own food. It is here that the transfer of electrons takes place.

It is the downhill flow of electrons that provides free energy for the creation of a proton chemical gradient. In whole chloroplasts each chlorophyll molecule is associated with an electron acceptor and an electron donor. What have you learned so far? To make food plants need: They again receive energy, but this time from light absorbed by P chlorophyll molecules.

Most plants are able to make their own food whenever they need it.

There is evidence that chloroplasts were once free living bacteria that invaded a non-photosynthetic cell long ago. In cyanobacteria, there are no chloroplasts and chlorophyll layers are dispersed in the cytosol.

What is the chemical equation for photosynthesis? The oxygen atoms released as molecular oxygen through photosynthesis come from water. Sunlight is absorbed by a green chemical in the leaves.

How do chloroplasts multiply? How is the light energy absorbed by chlorophyll transferred to ATP molecules during photophosphorylation?

Photosynthesis in the future Photosynthesis generates all the breathable oxygen in stereoselective synthesis book atmosphere, and renders plants rich in nutrients. This is known as carbon fixation.
