The given statements describes a group of organism I. Instead of a cell wall, they have a protein rich layer called pellicle which makes their body flexible II. They have two flagella a short and a long one III. They are photosynthetic in the presence of sunlight, when deprived of sunlight they behave like heterotrophs by predating on other smaller organism Which of the following group is referred here?

Question

Dr. Abubacker · Accepted Answer

Euglenoids are unicellular flagellate protists. Their cell wall do not contain cellulose. The body is covered by thin and flexible pellicle. The pellicle is composed of fibrous elastin protein, small amount of lipid or/and carbohydrate. The euglenoids have two flagella, usually one long and one short. They are photosynthetic in the presence of sunlight. In dark even photosynthetic forms can behave like heterotrophic, predating on smaller organisms (holozoic) or feeding on organic remains (saprobic)
