Question

A red blood cell will shrink in size when placed in a more concentrated salt solution because of the passive process called

A) biosis.
B) endocytosis.
C) mitosis.
D) osmosis.

Answer 1

osmosis, as water moves from a high water potential to a low water potential through a selectively permeable membrane, so the red blood cell shrinks

Answer 2

The correct answer would be D) osmosis.

Osmosis refers to the movement of water from the region of high salt or solute concentration to the region of low solute concentration through a semi permeable membrane.

Similarly, when a red blood cell is placed in more concentrated solution or hypertonic solution, the water moves from inside the cell to the outside solution.

Consequently, the cell shrinks in size.
