Cell affected by leukemia are

Options

A. Plasma cells
B. Thrombocytes
C. Leucocytes
D. Erythrocytes

Answer

**Step-by-Step Solution:**

1. **Understanding Leukemia**:
- Leukemia is a type of cancer that primarily affects the blood and bone marrow. It is characterized by the uncontrolled proliferation of abnormal white blood cells (leukocytes).

2. **Identifying the Affected Cells**:
- In leukemia, the cells that are primarily affected are the leukocytes (white blood cells). These cells multiply uncontrollably, leading to an increased number of leukocytes in the bloodstream.

3. **Analyzing the Options**:
- The question may provide several options, such as plasma cells, thrombocytes, erythrocytes, and leukocytes.
- Plasma cells are derived from B cells and are involved in antibody production, not directly affected by leukemia.
- Thrombocytes (platelets) are involved in blood clotting and are not the primary cells affected by leukemia.
- Erythrocytes (red blood cells) are responsible for oxygen transport and are also not the cells affected by leukemia.

4. **Conclusion**:
- The only correct answer is leukocytes, as they are the cells that undergo uncontrolled proliferation in leukemia.

**Final Answer**: The cells affected by leukemia are leukocytes (white blood cells).
