The chloroplasts are lens-shaped organelles found in leaves and other green organisms. In the green tissue, in the interior of the leaf, are mesophyll. Each mesophyll has about 30 or 40 chloroplasts. Chloroplasts are made up of saclike photosynthetic membranes. These membranes are in such an order ...

Peroxisomes also can occur in the leaves where they give off Carbon Dioxide, can be used in photosynthesis and in seeds where they convert oils into sugars.
