The document compares and contrasts the structures and functions of plant and animal cells. Both plant and animal cells contain a cell membrane, mitochondria, ribosomes, endoplasmic reticulum, Golgi bodies, cytoplasm, nucleus, nucleoplasm, and nucleolus. Unique to plant cells are cell walls, chloroplasts, and vacuoles that store food, water and chemicals. Animal cells contain lysosomes as garbage cans and lack cell walls. The structures work together to carry out the basic functions needed to keep the cell alive such as transport, energy production, waste removal and protein synthesis.
