Answer:
Flagellum helps the cells to move.
Explanation:
- The blunt, more rounded end is often the head part from which the whip-like tail (flagella) is attached because of the presence of a flagellum, Euglena are also known as flagellates.
- Although one flagellum is often seen, they have two flagella, one of which is often hidden in a part of the Euglena referred to as reservoir.
- The longer, visible flagellum located at the anterior end of the organism twirls rapidly making it possible for these organisms to move across water surface
Membrane
- Unlike most plant cells, this species do not have a cell wall.
- The organelles of the organism and its cytoplasm are therefore bound by a plasma membrane that allows for easier movement.
- Observation of Euglena under more powerful electron microscopes have revealed the presence of an ornamented pellicle under the plasma membrane.
- The presence of this thin protein layer protects the their cell membrane and also helps in maintaining their shape.
- Moreover, because of their flexible nature, they also facilitate movement.
