Components of Blood: Function
- Plasma plays a crucial role in transporting various substances such as carbon dioxide, digested nutrients, urea, mineral ions, hormones, and heat energy.
- Red blood cells are responsible for carrying oxygen from the lungs to cells in need of it for aerobic respiration. This oxygen is transported in the form of oxyhemoglobin.
- Oxygen is carried in the form of oxyhemoglobin by red blood cells.

| 2. How can you identify red blood cells under a microscope? | |
Ans. Red blood cells can be identified under a microscope by their biconcave shape, lack of a nucleus, and red color due to the presence of hemoglobin.
| 3. What are the characteristics of white blood cells that differentiate them from red blood cells? | |
Ans. White blood cells have a larger size, a nucleus, and the ability to move on their own (amoeboid movement) compared to red blood cells. They also play a crucial role in the immune response.
| 4. How do red blood cells contribute to the body's oxygen transport system? | |
Ans. Red blood cells contain hemoglobin, a protein that binds to oxygen in the lungs and carries it to tissues throughout the body. This process is essential for cellular respiration and energy production.
| 5. What is the significance of platelets in blood clotting? | |
Ans. Platelets are essential for blood clotting as they help seal off damaged blood vessels by forming a plug. They release clotting factors that initiate the formation of a fibrin mesh, which stabilizes the clot and stops bleeding.
