Detailed explanation-1: -The cell membrane, also called the plasma membrane, is found in all cells and separates the interior of the cell from the outside environment. The cell membrane consists of a lipid bilayer that is semipermeable. The cell membrane regulates the transport of materials entering and exiting the cell.

Detailed explanation-2: -The cell membrane surrounds the cell and controls the substances that go into and out of the cell. The nucleus is a structure inside the cell that contains the nucleolus and most of the cell’s DNA.

Detailed explanation-3: -Plasma membrane-controls what enters and leaves the cell (also present in eukaryotic cells) Ribosomes-the site of protein synthesis, (70s)

Detailed explanation-4: -Cell Membrane regulates what enters and leaves the cell and provides protection and support in Animal cells.

Detailed explanation-5: -The nucleus of a cell is a structure in the cytoplasm that is surrounded by a membrane (the nuclear membrane) and contains, and protects, most of the cell’s DNA.
