Question

Describe any two types of cell movement

Answer 1

By using pseudopodia: Single celled organisms like Amoeba and WBC's in higher organisms move with the help of pseudopodia. The cell membrane extend or protrude in various directions to form feet like structures which helps them to move from place to place.

By using flagella: Single celled organisms like Euglena and sperms in muticellular organisms use flagellar movement. Flagella is a whip like structure which lashes itself in the surrounding medium to propel further.

Answer 2

Cell, is the basic unit of Life.Cells are the smallest structures capable of basic life processes like reproduction, expelling waste out of the body , absorbing nutrients etc.
Following are the types of cell movement :
Flagella:--->Flagella are single and long structures.--> Some single celled Eukaryotic organisms such as Euglena and high animals like human sperm uses flagellum to swim towards the female egg for fertilization.--->A sperm cell's flagellum produces wave like movements , which propels a sperm cell forward  like the tail of an eel.

Pseudopodia:-->Eukaryotic cells such as amoebas and white blood cells, move by amoeboid motion or crawling. They extrude their cytoplasm to form temporary peudopodia or false feet.
