Plant cells are the basic building blocks of plants they have unique structure that are differentiates them from animals cells, such as the cell wall chloroplasts and a large central Plants cell are unique in structure and functions Major plants cell structure: Cell wall - outside of the cell and its structure Cell membrane Nucleus - the brain of the cell Cytoplasm Mitochondria Vacuole - liquid sac Cell surface membrane - keeps the cell together and controls what goes into and out of the cell Chloroplasts - Cell wall protects from stress Chloroplast converts energy from sunlight into chemical energy (glucose) Contains chlorophyll the green pigment Central vacuole large membrane-brond space filled with fluid. Maintains cell turgor pressure. Store nutrients, waste The important Plants cell structure is critical for a plants ability to grow and stay upright and perform vital functions like photosynthesis storage.
