The document defines and describes the key organelles and structures found within plant cells, including the cell wall, cell membrane, chloroplasts, golgi bodies, mitochondria, nuclear membrane, nucleus, ribosomes, rough endoplasmic reticulum, smooth endoplasmic reticulum, and vacuoles. The cell wall provides structure and support, while the cell membrane regulates what passes in and out. Chloroplasts use sunlight for photosynthesis, and mitochondria generate energy. The golgi body packages proteins and carbohydrates, and the nucleus contains DNA and controls cell functions. Ribosomes produce proteins, and the endoplasmic reticulum transports materials through the cell.
