7.2 Photosynthesis occurs in chloroplasts in plant. cells. ï§ Chloroplasts are concentrated in the cells of the. mesophyll, the green tissue in the interior of the. leaf. ï§ Stomata are tiny pores in the leaf that allow. carbon dioxide to enter and oxygen to exit. ï§ Veins in the leaf deliver water absorbed by roots.
REVISION: I disagree with the previous answer-the function of a mitochondria and a chloroplast are fundamentally different, indeed nearly opposite in many respects. Chloroplasts are the site of photosynthesis whereby light energy and carbon dioxide are utilized to form sugars. Mitochondria are the site of much of cellular respiration (parts of cellular respiration also occur in the cytoplasm) where oxygen and sugars are broken down to generate energy and carbon dioxide.
