Plant vs. Animal Cell Both: Nucleus, Mitochondria, Endoplasmic Reticulum, Golgi apparatus, vesicles, cytoskeleton Plant Cell Animal Cells Cell wall Centrioles Large central vacuole Plastids Cell Wall • Structure: rigid layer of carbohydrates (cellulose) outside cell membrane • Function: support and protection Central Vacuole • Structure: Large, fluid-filled organelle • Function: • Stores water, enzymes, metabolic wastes, and other materials • Allows plant to stand upright • Can make up 90% of the plant cell’s volume Plastids • Structure • Double membrane • Contain DNA • Types of plastids: 1. 2. 3. Chloroplast Chromoplast Amyloplasts What does this sound like? Chloroplast • Structure: • Contains thylakoids (flattened, membranous sacs) • Thylakoids contain chlorophyll (molecule that absorbs light energy for the cell) • Function: Use light energy to make carbohydrates from carbon dioxide and water = photosynthesis Evolution of Plastids and Mitochondria = Endosymbiosis
