WebJul 28, 2024 · Structure of Plant Cells Cell Wall Plant cells are eukaryotic cells, but unlike animal cells which have a cell membrane, plant cells have cell walls. Plants have a rigid cell wall that surrounds the plasma membrane. The cell wall is made of cellulose and lignin, which are strong and tough compounds. Plant Cells Labelled Plastids and Chloroplasts WebJun 12, 2024 · The cell membrane of the plant cell has a phospholipid bilayer. Plant cells often have a central vacuole, which is a large membrane-bounded sac that stores proteins, pigments, and waste materials. The central vacuole, in most mature plants, occupies a major portion of the internal volume of the cell and has a phospholipid bilayer. WebPlant cells have neither of these.
