There are no cells in a cell membrane.,
Yes, you will find it in a plant cell, an animal(human) cell and in a bacteria cell. It is required for one cell in order to be cell =]
Both. But of the two, the plant cell will also have a cell wall and the animal cell will not.
Its the cell covering, outside the cell
A Golgi apparatus packages things and ships them out of the cell, so it is located near the cell membrane.
Well some would be the nucleus, cell membrane, vacuoles and mitochondria.
The cell membrane can be found surrounding the cell, serving as a protective barrier that separates the inside of the cell from its external environment.
You would find a cell with all these structures in the leaf of a plant. These cells are typically found in the mesophyll tissue of the leaf, where photosynthesis takes place. The chloroplasts are responsible for photosynthesis, while the nucleus, cell wall, cell membrane, cytoplasm, and vacuole are essential components of plant cells for various functions.
Phospholipid head and protein
Cells membranes are made of a phospholipid bilayer. Phospholipids are tiny structures that have a hydrophilic (water-loving) "head" and a hydrophobic (fat-loving) tail. As i mentioned before, they are in a bilayer, so there are two rows of them that make up the membrane. The heads go towards the outside of the membrane, and the tails tend toward the fatty centre. Therefore, in the inside of cell membrane you would find lipids, or fats, and the "tails" of the phospholipids.
At the innermost surface of the plasma membrane of an animal cell, you would find peripheral proteins, integral proteins, and phospholipids directly exposed to the cytoplasm. These components help regulate the entry and exit of molecules, facilitate cell signaling and communication, and maintain the structural integrity of the membrane.
The cell membrane controls what enters and leaves the cell, allowing the cell to absorb the oxygen and nutrients it needs to function. It also protects the cell from most dangerous chemicals. The cell membrane is vital because the cell needs to be able to control its oxygen and carbon dioxide levels.
