The correct answer is: A. Chlorenchymatous cells.
Chlorenchymatous cells are plant cells that contain chloroplasts, which are the organelles that carry out photosynthesis. Chloroplasts contain chlorophyll, which is a green pigment that absorbs sunlight and uses it to convert carbon dioxide and water into glucose and oxygen.
Sclerenchymatous cells are plant cells that provide support and strength. They are dead at maturity and have thick, lignified cell walls.
Parenchymatous cells are plant cells that are involved in a variety of functions, including photosynthesis, storage, and secretion. They are living cells with thin cell walls.
Therefore, the correct answer is A. Chlorenchymatous cells.
