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.
All eukaryotic cells have a plasma membrane.
yupp cheek cells are animal cells so they have cell membranes
Yes all cells have cell membranes
Yes, plants have cell membranes. Plant cells differ from animal cells in that plant cells also have cell walls.
Cell membranes allow nutrients into cells and waste products pass out of cells. Cell membranes provide a protective barrier for cells — they don't let everything in, especially large particles. Cell membranes are important in the communication between cells. Cell membranes are reservoirs for fatty acids.
All cells have cell membranes. However only plant cells have a cell wall as well.
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
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.
Eukaryotic cells have cell membranes.
