long-whip like structures on the protist euglena that allow them to move and capture food
A
flagella
B
psuedopod
C
cilia
D
spirilla
Explanation: 

Detailed explanation-1: -The euglena has a long, whip-like structure called a flagellum on its front end that twirls like a miniature motor on a boat to propel it through water. Also outside the cell membrane, a stiff pellicle (thin skin or film) helps the euglena retain its oblong shape.

Detailed explanation-2: -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. It is attached at an inward pocket called the reservoir.

Detailed explanation-3: -Euglena are unique in that the outer layer of the cell includes a flexible membrane called the pellicle. The pellicle supports and contains the plasma membrane, much like a cell wall would in plants.

Detailed explanation-4: -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-5: -Zooflagellates are a third type of protists. They are animal-like and move by using flagella. 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.
