[Review question: Pg. No: 231]

Answer 1

There are three types of movements:

1. Amoeboid movement:
It is brought about by pseudopodia which are appendages which move with movement of protoplasm within a cell.

2. Ciliary movement:
This movement is brought about by appendages called as cilia which are the hair-like extensions of the epithelium. Both these kinds of movements are seen with cells of the lymphatic system.

3. Muscular movement:
It is a more complex movement which is brought about by the musculoskeletal system. This type of movement is seen in the higher vertebrates.
Example: Human beings.
