Question

What is and cilia and flagella?

Answer 1

Cilia is the cytoplasmic extension attached to the plasma membrane.

Flagella is a hairlike structure, which is attached to the living cells

Step-by-step explanation:

Cilia is the cytoplasmic extension that is attached to the plasma membrane of the cells. It is composed of the microtubules and the dyneins motor proteins.

The function of cilia is to assist the cell in locomotion, it also presents in the trachea respiratory tract, where they help in removal of the microbes and particles.

Flagella is the threadlike extension of unicellular organisms that facilitates in the movement of the cells.

Answer 2

Well, Cilia and flagella are actually projections from the cell.
They are precicly made up of microtubules, they are also covered by an extension of the plasma membrane. They are motile and designed either to move the cell itself or to move substances over or around the cell.
