EVERYDAY SCIENCE

Detailed explanation-1: -Palisade mesophyll cells are tall and have large number of closely packed chlorophyll molecules to absorb maximum light. Most photosynthesis takes place in the palisade cells.

Detailed explanation-2: -In leaves, cells in the mesophyll (the tissue between the upper and lower epidermis) are uniquely suited to carry out photosynthesis on a large scale. This is due to their high concentration of chloroplasts, which are the sites of photosynthesis.

Detailed explanation-3: -Even more specifically, the palisade layer has the most chloroplasts, so the greatest amount of photosynthesis occurs in that leaf layer.

Detailed explanation-4: -Palisade cells contain the largest number of chloroplasts per cell, which makes them the primary site of photosynthesis in the leaves of those plants that contain them, maximizing the production of energy, converting the energy in light to the chemical energy of carbohydrates.

Detailed explanation-5: -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.
