Question

part b: cell transport review: identify each image as: diffusion, osmosis, facilitated diffusion, endocytosis. note: terms may only be used once. 2. 5. 6.

Explanation:

1. Diffusion is the movement of particles from an area of high - concentration to an area of low - concentration. The first image with particles spreading out is diffusion.
2. Facilitated diffusion uses carrier proteins to move substances across the cell membrane. The image with carrier proteins and solute movement is facilitated diffusion.
3. Osmosis is the diffusion of water across a semi - permeable membrane. The image showing water movement across the cell membrane is osmosis.
4. Endocytosis is the process by which cells take in substances by engulfing them with the cell membrane. The image with the cell membrane forming vesicles around substances is endocytosis.
5. The image with particles moving from high to low concentration across the membrane without carrier proteins is diffusion.
6. The image showing the release of secretory products from vesicles fusing with the plasma membrane is exocytosis (not in the given options, but based on the image).

Answer:

1. Diffusion
2. Facilitated diffusion
3. Osmosis
4. Endocytosis
5. Diffusion
6. Exocytosis (not in options but based on image)
