The document outlines the key organelles found within plant and animal cells and their functions. It describes the cell membrane, cell wall, nucleus, cytoplasm, endoplasmic reticulum, ribosomes, Golgi bodies, mitochondria, plastids, vacuoles, and lysosomes. The nucleus controls most cell activities and contains DNA. The mitochondria produce energy for the cell and are abundant in muscle cells. Plant cells contain organelles like chloroplasts and vacuoles not found in animal cells.
