Talk about the characteristics of a plant cell.

Plant cells have some specific characteristics that differ from the animal cells. At the ultra-structural level, the cell is surrounded by a cell wall; the cytoplasm encloses a large vacuole and plastids. Cellulose is the main component of the cell wall. Starch is the main carbohydrate reserve. Chlorophylls, are the photosynthetic pigments. They are light energy receptors necessary for photosynthesis and give the green color to the plastids (chloroplasts) in which they are found. However, these criteria do not have an absolute value and does not apply to all green plants.
