Question

Match the following

$\begin{array}{cc}\text{A. Macrophages}& \text{1. Ciliary movement}\\ \text{B. Passage of Ova}& \text{2. Amoeboid Movement}\\ \text{C. Movement of jaw}& \text{3. Muscular movement}\\ \text{D. Hindlimbs}& \text{4. Locomotion}\end{array}$

• A. A-2, B-3, C-4, D-1
• B. A-4,B-1, C-2, D-3
• C. A-1, B-4, C-2, D-3
• D. A-2, B-1, C-3, D-4

Answer 1

The correct option is D A-2, B-1, C-3, D-4

The movement of the jaw is brought about by voluntary muscles. Hence, it is muscular movement.

Amoeboid movements are movements brought about the outward projection of the cytoplasm and this movement appears like a dragging or crawling movement. The cytoskeleton helps in amoeboid movement in macrophages, which are cells involved in immunity.

Ciliary movement involves the coordinated movements of cilia, which are hair-like structures. The cilia present in the reproductive tract are responsible for the passage of ova.

The skeletal muscles in hindlimbs help in locomotion, e.g., when humans run or walk.
