Name the cells which help in clotting of blood in mammals

Options

A. Platelets
B. Thrombocytes
C. Lymphocytes
D. Monocytes.

Answer

**Step-by-Step Text Solution:**

1. **Understanding the Question**: The question asks for the specific cells involved in the clotting of blood in mammals.

2. **Identifying the Options**: The options provided are:
- A) Platelets
- B) Thrombocytes
- C) Lymphocytes
- D) Monocytes

3. **Analyzing Each Option**:
- **Option A: Platelets** - These are small cell fragments in the blood that play a crucial role in hemostasis (the process of blood clotting). They aggregate at the site of a blood vessel injury and form a plug to stop bleeding.
- **Option B: Thrombocytes** - While thrombocytes are involved in clotting, they are primarily found in invertebrates. In mammals, the term "thrombocytes" is often used interchangeably with "platelets," but they are not the primary term used for mammalian blood clotting.
- **Option C: Lymphocytes** - These are a type of white blood cell that is part of the immune system and are not involved in blood clotting.
- **Option D: Monocytes** - These are another type of white blood cell that helps fight infections but do not play a direct role in blood clotting.

4. **Conclusion**: Based on the analysis, the correct answer is **Platelets** (Option A), as they are the cells that help in the clotting of blood in mammals.

**Final Answer**: Platelets.
