Amoeboid movement is found in `:-`

Options

A. Limbs, Jaw
B. Macrophages, Leucocytes
C. Trachea, Fallopian tube
D. Tongue, Leucocytes

Answer

**Step-by-Step Solution:**

1. **Understand Amoeboid Movement**:
- Amoeboid movement is a type of movement characterized by the formation of temporary cytoplasmic projections known as pseudopodia (meaning "false feet"). This movement allows cells to change shape and move in a crawling manner.

2. **Identify Where Amoeboid Movement Occurs**:
- Amoeboid movement is primarily observed in certain protozoans like amoeba. In humans, this type of movement is notably found in specific types of white blood cells.

3. **Recognize the Types of Cells Involved**:
- The two main types of cells in humans that exhibit amoeboid movement are leukocytes (white blood cells) and macrophages.
- Leukocytes are crucial for immune responses, while macrophages help in phagocytosis, which is the process of engulfing and destroying dead cells and pathogens.

4. **Eliminate Other Options**:
- The other options provided (limbs, jaw, trachea, fallopian tube, tongue) do not exhibit amoeboid movement. Instead, limbs and jaws utilize muscular movement, while the trachea and fallopian tubes exhibit ciliary movement.

5. **Conclude the Answer**:
- Based on the information, the correct answer to the question "Amoeboid movement is found in" is **macrophages and leukocytes**.

**Final Answer**: Amoeboid movement is found in macrophages and leukocytes.
