Final answer:
Particles can move through the membrane in five ways: simple diffusion, facilitated diffusion, active transport, endocytosis, and exocytosis.
Step-by-step explanation:
Particles can move through the membrane in five ways:
- Simple diffusion: Small, non-polar particles move from an area of higher concentration to an area of lower concentration.
- Facilitated diffusion: Larger or charged particles move through specific protein channels in the membrane.
- Active transport: Certain particles are actively pumped across the membrane using energy from the cell.
- Endocytosis: Large particles are engulfed by the membrane and brought into the cell in a vesicle.
- Exocytosis: Vesicles containing particles fuse with the membrane and release the particles outside the cell.
