Correct Answer � C
Explanation
|
|
Ans. C. Diffusion
- Substances can move by simple diffusion directly along the pores and channels from one side of the membrane to the other.
Thus, simple diffusion can occur through two pathways.
- Through membrane lipid bilayer → for lipid-soluble substances.
- Through pores (water channel) –> for ions/electrolytes.
