Question

Cilia and flagella differ in that

• A. cilia are made of microfilaments and flagella is made of microtubules
• B. cilia are involved in the movement of the organism and flagella are helpful in the process of engulfing food
• C. cilia are short and found in large numbers on the cell surface whereas flagella are long and fewer in number
• D. cilia are found in prokaryotic cells and flagella in eukaryotic cells

Answer 1

The correct option is C cilia are short and found in large numbers on the cell surface whereas flagella are long and fewer in number

Cilia and flagella are cell organelles which are structurally similar but they differ in their function. They are both present on the surface of cells.

Cilia are short thin appendages that are many in number and present throughout the surface of the cell. Flagella are long structures which helps only in the movement. There are only a few flagella (< 3) in a cell.

Cilia and flagella are similar in their structural organisation both are made up of microtubules.

Both cilia and flagella helps in locomotion. Apart from this cilia helps in engulfing food.

Cilia are found in eukaryotic cells but flagella is present in both prokaryotic as well as in eukaryotic cells.
