Question

what does the red blood cell in the figure depict?

• crenation
• no change
• hemolysis
• plasmolysis

Explanation:

Analyze cell morphology

The image shows a red blood cell with a shriveled, spiked, and scalloped appearance.

Identify environmental tonicity

The surrounding medium contains a high concentration of solute particles (represented by the small grey spheres). This indicates a hypertonic environment.

Determine water movement

Water leaves the cell via osmosis to balance solute concentrations, causing the cell to shrink.

Match with biological terminology

The shriveling of an animal cell (like a red blood cell) in a hypertonic solution is called crenation.

Answer:

• (A) Crenation (Correct answer)
• (B) No change
• (C) Hemolysis
• (D) Plasmolysis
