Medium Open in App Solution Verified by Toppr

Some characteristic features of Euglenoids are as follows.

• Euglenoids (such as ) are unicellular protists commonly found in fresh water.

• Instead of the cell wall, a protein-rich cell membrane known as pellicle is present.

• They bear two flagella on the anterior end of the body.

• A small light sensitive eye spot is present.

• They contain photosynthetic pigments such as chlorophyll and can thus prepare their own food. However, in the absence of light, they behave similarly to heterotrophs by capturing other small aquatic organisms.

• They have both plant and animal-like features, which makes them difficult to classify and hence they are called as connecting link between plants and animals.

- They are the unicellular protists.

- They are found in the freshwater.

- They have a pellicle present- which is a protein-rich membrane.

- They lack a cell wall.

- They have two flagella on the anterior of the body.

- They can prepare their food by photosynthetic pigments called chloroplasts.

- In the absence of light, they acquire food as heterotrophs. They will then feed on other organisms for feed.

- They have a contractile vacuole to regulate the fluid in the cytoplasm.

- They are usually red due to the presence of carotenoids.

- They attack their food and eat via phagocytosis in which the entrapment of food takes place by an outer membrane.

- They reproduce by longitudinal cell division, a form of asexual reproduction mode.
