Question

Name the organs meant for ciliary and amoeboid movements.

Answer 1

Hint: The ciliary movement is done by the epithelial cells and microtubule as the cytoskeleton plays an important role in this movement. Amoeboid movement is a locomotor movement.

Complete answer:
The ciliary movement is caused by the cilia in the protozoans or the mammalian cells and the amoeboid movement is caused by the pseudopodia present in the amoeba. The cilia are hair-like structures present on the outer surface of the eukaryotic cells, very small and slender in nature, and can be in many large numbers. The ciliates or the organisms having cilia use them for feeding that is mainly as a result of the mechanoreception and even the chemicals or the substrates can be sensed by the cilia and allow the organism to move towards the food. Cilia can be motile or non-motile and mainly consist of microtubules and single cilia consist of nine triplets microtubules on the outer ring structure and cover the inner two microtubule structure attached to the cell body.
-The pseudopodia come from pseudo that means false and podia meaning legs. They are named so because they can form projections from the cell body and after the locomotory movement regain the shape again as if the projections formed were false. They mainly consist of cytoplasm and actin as their cytoskeleton structure that helps to sense the food and engulfs it via phagocytosis and forms a food vacuole that is then ingested completely by the cell.
Hence, the organs meant for ciliary and amoeboid movement are cilia and pseudopodia respectively.

Note: Human mesenchymal cells also perform amoeboid-like movement and also macrophages perform phagocytosis like an amoeba. The main sensory functions are possessed by the non-motile cilia.
