NEET BIOLOGY

Detailed explanation-1: -Euglena usually live in quiet ponds or puddles. Euglena move by a flagellum (plural flagella), which is a long whip-like structure that acts like a little motor. The flagellum is located on the anterior (front) end, and twirls in such a way as to pull the cell through the water.

Detailed explanation-2: -Euglena move by using a flagellum, a long whip-like structure that functions as a small motor. The flagellum, which is located on the cell’s anterior (front) end, twirls to propel it through the water.

Detailed explanation-3: -Demembranated flagella from Euglena gracilis consisted of three distinct components: a 9 + 2 axoneme of microtubules, an extensive surface coating of long and short mastigonemes and a lattice-like axial fibre known as the paraflagellar rod.

Detailed explanation-4: -Flagella are whip-like structures that spin quickly, working like a boat’s propeller to move the organism through water. Most zooflagellates have from one to eight flagella that help them move. Giardia is a protist that moves with flagella. They can be found in freshwater streams and lakes.

Detailed explanation-5: -Euglena move with a single flagellum, so they are called flagellates.
