Detailed explanation-1: -In plants, the cell wall surrounds the cell membrane. This gives the plant cell its unique rectangular shape. Animal cells simply have a cell membrane, but no cell wall.
Detailed explanation-2: -Animal cells do not have cell walls. The cell membrane is a protective layer that surrounds every cell. It separates it from its external environment. It is found just inside the cell wall and is made up of complex lipids (fats) and proteins.
Detailed explanation-3: -Nucleus. The nucleus is the “brain” of the cell because it directs what happens within the cell. It contains the cell’s genetic information called deoxyribonucleic acid (DNA). The DNA provides the information required for making the proteins that control the activities of the cell.
Detailed explanation-4: -Cell Membrane. A thin semipermeable membrane layer of lipids and proteins surrounding the cell. Nucleus. It is an organelle that contains several other sub-organelles such as nucleolus, nucleosomes and chromatins. Nuclear Membrane. Centrosome. Lysosome. Cytoplasm. Golgi Apparatus. Mitochondrion.
