Question
Movement of substances across the cell membrane occurs throughDiffusionOsmosisBulk transport All of the above
Solution
All of the above. Movement of substances across the cell membrane can occur through diffusion, osmosis, and bulk transport.
-
Diffusion: This is a process where molecules move from an area of high concentration to an area of low concentration. It doesn't require energy.
-
Osmosis: This is a special type of diffusion where water molecules move across a semi-permeable membrane from an area of low solute concentration to an area of high solute concentration.
-
Bulk transport: This involves the movement of large particles or numerous particles at once. It can be either endocytosis (into the cell) or exocytosis (out of the cell). This process requires energy.
