An animal cell is made of a nucleus, a cell membrane, endoplasmic reticulum, mitochondrion, a nucleolus, Golgi bodies, ribosomes, lysosomes, and chromosomes. They are not that â¦ different from improved animal cells but different from human cells and improved human cells.es, a cell membrane is a organelle that both animal and plant cells share. Yes they do,(A nimal cells do not have a cell wall,A nimal cells have only the membrane to contain and protect) . yes they do have a cell membrane.
The cell membrane is the outermost barrier of an animal cell. As for plants, the cell membrane is surrounded by the cell wall, which gives the cell a much more rigid structure. To clarify, all cells have a plasma membrane. The function of the cell membrane is to protect the cell and control the transport from the inside to the outside of the cell. It contains transport signaling systems such as protein channels through which substances such as salts pass.
