Chloroplasts are organelles found in plant cells and in algae. [1]

Contains the green pigment chlorophyll; the site of photosynthesis. [2]

The process of photosynthesis occurs in the chloroplast

1. Water is a raw material for photosynthesis.

2. Light energy reaches the chlorophyll molecules.

3. Light energy splits the water molecules into oxygen and hydrogen.

- The hydrogen reduces the carbon dioxide to form glucose

4. Oxygen is released as a waste product.

5. Glucose is often stored as starch grains (small granules found in the leave, serve as energy reserves for plants.).

6. Hydrogen and carbon dioxide react to form glucose, catalysed by enzymes.

7. Carbondioxide can diffuse into the region between the green membranes.

How do the chloroplasts adapt for photosynthesis

- Palisade cells are filled with chloroplasts

- Chloroplasts can move within the cell to make best use of available light.

- The chloroplast's membrane contains the chlorophyll molecules that can trap light energy.
