do plant cells have epithelial cells
Cell Surface. While both onion and human cells have a cell membrane, only the onion has a cell wall. Both plant and animal cells, including human epithelial, and onion epidermal cells have a structure called a cell membrane or plasma membrane. This membrane holds everything in the cells and is comprised of a phospholipid bilayer, a structure made of oily molecules, held together by the interaction of these molecules with water.
