Question

In blood, platelets are required for

  1. A. Transporting oxygen
  2. B. Transporting carbon dioxide
  3. C. Initiating clotting of blood (Correct answer)
  4. D. Immunity

Correct Answer

Option C — Initiating clotting of blood

Detailed Solution & Explanation

The correct answer is Initiating clotting of blood.

Key Points

  • Platelets (thrombocytes) are small, colorless cell fragments in blood that play a crucial role in blood clotting (hemostasis).
  • When a blood vessel is injured, platelets aggregate at the site and release chemicals that trigger the clotting cascade.
  • RBCs transport oxygen/CO₂; WBCs provide immunity.
