Osmosis is the movement of _________ molecules from a region of higher concentration to a region of lower concentration through a semipermeable membrane.
The correct option is: D
Explanation of the correct option:
Osmosis is the movement of water molecules from a region of higher concentration to a region of lower concentration through a semipermeable membrane.
For example - Root hairs absorb water through the process of osmosis. The concentration of the water molecules is lower in the root hair than in the soil. So the water moves into the root hairs through osmosis.
Explanation of the incorrect option:
Option A: Osmosis is the movement of water molecules from a region of higher concentration to a region of lower concentration through a semipermeable membrane.
Option B: Osmosis is the movement of water molecules from a region of higher concentration to a region of lower concentration through a semipermeable membrane.
Option C: Osmosis is the movement of water molecules from a region of higher concentration to a region of lower concentration through a semipermeable membrane.
Final answer: Osmosis is the movement of water molecules from a region of higher concentration to a region of lower concentration through a semipermeable membrane.
