Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
CILIA andFLAGELLA both aid in movement BUT cilia are
A
small feet
B
small hairs
C
small contractile vacuoles
D
None of the above
Explanation: 

Detailed explanation-1: -They both contain inner growth along with outer growth of cytoplasm.

Detailed explanation-2: -The motion of cilia is rotational, very fast moving. The motion of flagella is rotary movement in prokaryotes whereas it is bending movement in eukaryotes. Cilia beat in coordination or one after the other. Flagella beat independent of each other.

Detailed explanation-3: -Cilia and flagella are antenna-like protrusions present on many types of eukaryotic cells. Consequently, they have evolved to perform diverse functions, such as locomotion, mucus clearance, fluid circulation, chemosensation, and mechanosensation.

Detailed explanation-4: -The primary function of cilia and flagella is movement. They are the means by which many microscopic unicellular and multicellular organisms move from place to place. Many of these organisms are found in aqueous environments, where they are propelled along by the beating of cilia or the whip-like action of flagella.
