Detailed explanation-1: -The correct answer is 1 and 3 only. The cell wall is the outer covering of a cell. It surrounds the plasma membrane of plant cells and provides tensile strength and protection against mechanical and osmotic stress. The cell wall is present in plant cells and absent in animal cells.
Detailed explanation-2: -Animal cells each have a centrosome and lysosomes, whereas plant cells do not. Plant cells have a cell wall, chloroplasts and other specialized plastids, and a large central vacuole, whereas animal cells do not.
Detailed explanation-3: -Three differences between a plant cell and an animal cell are: Animal cell lack cell wall, unlike a plant cell which has a cellulosic cell wall. Animal cell lack chloroplast, whereas plant cell has chloroplast. Animal cell has centrioles, centrosome, and lysosome but plant cell lack them.
