- B. Lysosome
- C. Nucleus
- D. Endoplasmic reticulum

About Animal and Plant Cell
Animal and plant cells share a plasma membrane, cytoplasm, nucleus, ribosomes, mitochondria and endoplasmic reticulum, but plant cells also have a cellulose cell wall, chloroplasts and a large permanent vacuole. Questions cover organelle structure and function, differences between the two cell types, and how membranes control movement of substances.
