Question

Macrophages and leucocytes exhibit

• A. Gliding movement
• B. Flagellar movement
• C. Amoeboid movement
• D. Ciliary movement

Answer 1

The correct option is C Amoeboid movement

Ciliary movement:

• Cilia are hairlike structures that act as locomotory appendages for several organisms. These structures are also found in the lining of respiratory tracts. The movement caused by cilia is called ciliary movement.
• Cilia of the respiratory tract removes the dust particles and microbes.

Flagellar movement:

• Movement caused by flagella is called flagellar movement.
• The tails of sperm of humans show flagellar movement.

Amoeboid movement:

• Type of movement that involves the protrusion of the cytoplasm which results in the formation of pseudopodia is called amoeboid movement.
• Macrophages and leukocytes are phagocytic and they exhibit the amoeboid movement.

Gliding movement:

• Gliding movement occurs between the surfaces of two flat bones.
• Bones of the wrists and ankles show gliding movement.

Final answer: Amoeboid movement

Summary:

As macrophages and leucocytes are phagocytic, they engulf the foreign particles forming pseudopodia, they show amoeboid movement. Hence the correct option is c.
