Question

Describe how a plant cell is specialized for photosynthesis at

a. the level of organelles and other cellular structures
b. the molecular level

Answer 1

In plants and algae, which developed much later, photosynthesis occurs in a specialized intracellular organelle—the chloroplast. Chloroplasts perform photosynthesis during the daylight hours. The immediate products of photosynthesis, NADPH and ATP, are used by the photosynthetic cells to produce many organic molecules.
