First off, what is a cell? Cells are the smallest life form that can live on it’s own. Cells make up all living organisms and the tissues of the body. Cells has three main parts: the cell membrane, the nucleus, and the cytoplasm. A cell membrane (also known as the plasma membrane) separates the interior of the cell from the outside situation. The cell membrane involves a lipid bilayer that is passable. The cell membrane manages the move of stuff entering and exiting cells. Cytoplasm is a thick solution that fills each cell and is enclosed by the cell membrane. Cells are made up of molecules including nucleic acids, proteins, carbohydrates, and lipids. The cell that can live without other cells is the Amoeba cell. The 2 main cells in humans are prokaryotic and eukaryotic. Prokaryotic cells lack a nucleus and other membrane-bound organelles. Eukaryotic cells have a nucleus and other membrane-bound organelles.
