Question

An example of amoeboid movement is
A) Limbs
B) Leucocytes
C) Trachea
D) None of the above

Answer 1

Amoebae (e.g. Amoeba proteus) are found in this form of movement. Their cytoplasm comprises a much more viscous plasmagel-surrounded plasmasol.

Complete Answer:
The most popular type of locomotion in eukaryotic cells is amoeboid movement. It is a creeping method of movement performed by protrusion of the cell cytoplasm including the development of pseudopodia and posterior uropods. Now, let us find the solution from the options-
- As the cytoplasm slips, motion happens and creates a pseudopodium in front to force the cell forward. Thus, option A is not the correct option.
- Amoeboid motion: Amoeboid activity is demonstrated by leukocytes found in the blood.
Ciliary movement: Ciliary motion is demonstrated by reproductive cells such as sperm and ova.
Muscular movements: The muscular tissue located within the heart, the digestive organs and the blood vessels are used in the body to transfer substances. Leukocytes are also an instance of the movement of amoeboids.

- The trachea, also known as the windpipe, is the cartilaginous tube which binds the larynx to the lungs' bronchi, enabling air to flow through, and is therefore present in nearly all lung-breathing species. Thus, option C is not the correct option.

Thus, the correct answer is option (B) Leucocytes.

Note: Based on the organism, one or maybe more pseudopodia can be formed at a time, but all amoeboid activity is distinguished by the activity of amorphous organisms that have no fixed motility frameworks. The plasmagel is transferred to plasmasol, allowing the cytoplasm to slip and create a front pseudopodium to drive the cell forward.
