Question

When viewed through a microscope, one characteristic of living cells is that their internal structures move. what organelles are most directly responsible for this motion we see?

Answer 1

The cell has a skeleton-like structure called the cytoskeleton made of various kinds of fibres. The cytokeleton gives a shape to the cell, holds the various organelles in place, and allows for the movement of parts of the cell. The actin filaments are fibrous structures of the cytoskeleton that help in the contraction and expansion of the cell body. It also allows for the locomotion of the cell in space through the cytoplasmic extensions called the psuedopods (false-legs).
