WebTranscribed image text: The cytoplasm of certain cells (e.g. brain cells) has a high concentration of hydrophilic K+ ions. If there is already a high concentration inside the cell and a low concentration outside, how might K+ ions continue to enter the cell? O facilitated diffusion It is not possible for K+ to enter the cell. In cell biology, the cytoplasm is all of the material within a eukaryotic cell, enclosed by the cell membrane, except for the cell nucleus. The material inside the nucleus and contained within the nuclear membrane is termed the nucleoplasm. The main components of the cytoplasm are cytosol (a gel-like substance), the organelles (the cell's internal sub-structures), and various cytoplasmic inclusions. The cytoplasm is about 80% water and is usually colorless.
