Plant cells are eukaryotic cells (cells with a definite nucleus) found in green plants, which are photosynthetic eukaryotes of the kingdom Plantae. Parts of a plant cell: Cell walls:  Plant cells have cell walls (found outside the cell membrane) which are made up of cellulose, hemicelluloses, and pectin. It supports and protects the cell from damage. It is vital to not confuse cell walls with cell membranes. Vacuole:  It has a large central vacuole that sustains the cell's turgor, controls movement of molecules, stores useful material such as phosphorus and nitrogen,  and digests waste proteins a...
