Question

question 6. selectively permeable membrane a. endocytosis b. osmosis c. diffusion d. active transport

Explanation:

The diagram shows the movement of particles from an area of higher concentration to an area of lower concentration across a selectively - permeable membrane without the use of energy. This is the definition of diffusion. Endocytosis is the process of taking in substances by the cell membrane forming a vesicle. Osmosis is the movement of water molecules across a selectively - permeable membrane. Active transport requires energy to move substances against a concentration gradient.

Answer:

B. Diffusion
