The document describes the main parts of an animal cell including the cell membrane, endoplasmic reticulum, nucleus, ribosomes, Golgi bodies, mitochondria, lysosomes, nuclear membrane, and vacuole. It notes that plant cells contain chloroplasts and a cell wall that animal cells do not have. The chloroplasts contain chlorophyll and are where photosynthesis occurs, while the cell wall protects the plant cell and gives it a rigid shape.
