Question

identify each image as: diffusion, osmosis, facilitated diffusion, active transport, exocytosis or endocytosis. 21. 22. 23. 24. 25. 26.

Explanation:

1. Shows movement of ions against concentration gradient with energy input and carrier - protein, so it is active transport.
2. Particles move from high to low concentration without any assistance, which is diffusion.
3. The process of taking in solid particles by forming a vesicle is phagocytosis, a type of endocytosis.
4. Movement of molecules through carrier - channels from high to low concentration is facilitated diffusion.
5. Movement of water (H2O) across a semi - permeable membrane from high to low water concentration is osmosis.
6. Secretory vesicles fusing with the plasma membrane to release products outside the cell is exocytosis.

Answer:

1. Active transport
2. Diffusion
3. Endocytosis (phagocytosis)
4. Facilitated diffusion
5. Osmosis
6. Exocytosis
