That makes... No sense. How can a cell membrane be there when there is no cell?
Okay, well, I'll just tell you the gist of what a cell membrane consists of:
It has a phospho-lipid bi-layer with hydrophilic phosphate heads and hydrophobic tails. Heads are polar, tails are nonpolar. Um... obviously, it's a membrane, meaning it's on the outside of the cell. It's semi-permeable with both active and passive transport proteins allowing passage.
Plant cells have cell walls, animal cells have cell membranes. Cells do not have both walls and membranes, they have one or the other.
yupp cheek cells are animal cells so they have cell membranes
Yes, the cells of archaebacteria, bacteria, protists, fungi, plants and animals all have cell membranes. (Viruses have protein coats, not cell membranes and thus are not true 'cells'.) Thus indeed, all cells possess a cell membrane.
Yes, plants have cell membranes. Cell membranes are found in all living cells, including plant cells, and they serve as a protective barrier that controls the movement of substances in and out of the cell.
All cells contain membranes, so yes. Did you take science?
Plant cells do have cell membranes, which are covered by the cell walls.
Yes, eukaryotes in animal cells have cell membranes. The cell membrane is a semi-permeable barrier that surrounds the cell, regulating the passage of substances in and out of the cell. It plays a crucial role in maintaining the cell's internal environment and protecting the cell from its surroundings.
Yes. Both kinds of cells have nuclear membranes. They also have cell membranes, though plant cell membranes are also enclosed in the cell wall.
cell membranes and plasma membranes
Eukaryotic cells have cell membranes.
cell membranes
Animal cells do not have cell walls--only cell membranes. All cells have cell membranes made of a phospholipid bilayer. Cell walls, which are located outside of a cell's membrane, are made of various materials depending on the type of cell. They are found in plants (cellulose), fungi (chitin) and bacteria (peptidoglycan).
