      B transporting carbon dioxide Correct Answer Incorrect Answer
      C initiating blood clotting Correct Answer Incorrect Answer
      D initiating degradation of urea Correct Answer Incorrect Answer

      Solution

      Platelets (thrombocytes) are essential for initiating blood clotting. They help form a plug at the site of injury by releasing clotting factors that lead to the formation of fibrin threads. Platelets do not transport gases or degrade urea. Information Booster:      

      1. Platelets are cell fragments derived from megakaryocytes.
      2. Normal platelet count is 150,000–450,000 per microliter of blood.
      3. Platelets play a role in wound healing.
      4. Deficiency of platelets can lead to excessive bleeding (thrombocytopenia).
      5. Overproduction can cause unwanted clots (thrombosis).
