Explanation:
Detailed explanation-1: -Cilia and flagella are cell organelles that are structurally similar but different in length and function. Cilia are present in organisms such as paramecium, while flagella can be found in bacteria and sperm cells. Cilia are shorter and more numerous than flagella.
Detailed explanation-2: -Cilia are short, numerous, hair-like projections from the plasma membrane. They move in a “wave” motion. The cilia move the cell by beating rhythmically. Flagella function to move the cell by one long projection that moves in a whip-like motion.
