ANIMAL CELL CELL MEMBRANE STRUCTURE • Surrounds the cell FUNCTION • Holds contents of cell inside (like skin) • Keeps harmful substances out • Controls what enters and leaves • Water, oxygen, and nutrients are allowed to enter • Waste products are allowed to exit CYTOPLASM STRUCTURE • Clear, thick, jelly-like fluid (like Jell-o) FUNCTION • Chemical reactions take place here • Cytoskeleton in the cytoplasm helps the cell maintain or change its shape (just like your skeleton) NUCLEUS STRUCTURE • Round • Contains the DNA, which is long, thin threads of genetic material FUNCTION • Control center- directs all cell activities (like a brain) MITOCHONDRIA STRUCTURE • Bean shaped • Each cell has many mitochondria • Active cells have more mitochondria than less active cells FUNCTION • Powerhouse of the cell • Release chemical energy from food VACUOLE STRUCTURE • Animal cell has many • Small, round FUNCTION • Storage compartment • Holds food and water for the cell PLANT CELL CELL WALL STRUCTURE • Tough, rigid outer covering (like a wall to a building) FUNCTION • Protects the cell • Gives the cell shape (plants do not have a skeleton like animals) CELL MEMBRANE STRUCTURE • Surrounds the cell • Inside the cell wall FUNCTION • Holds contents of cell inside (like skin) • Keeps harmful substances out • Controls what enters and leaves • Water, oxygen, and nutrients are allowed to enter • Waste products are allowed to exit CYTOPLASM STRUCTURE • Clear, thick, jelly-like fluid (like Jell-o) FUNCTION • Chemical reactions take place here • Cytoskeleton in the cytoplasm helps the cell maintain or change its shape (just like your skeleton) NUCLEUS STRUCTURE • Round • Contains the DNA, which is long, thin threads of genetic material FUNCTION • Control center- directs all cell activities (like a brain) WATER VACUOLE STRUCTURE • Plant cell has 1-2 • Very large FUNCTION • Storage compartment • Holds water for the cell • Helps to support the plant CHLOROPLASTS STRUCTURE FUNCTION • Green (contains chlorophyll) • Bean shaped • Photosynthesis- makes food for plants MITOCHONDRIA STRUCTURE • Bean shaped FUNCTION • Release chemical energy stored from photosynthesis
