Q. The given statements describes a group of organisms I. The pellicle is composed of fibrous elastic protein lipid or carbohydrates and maintains a definite shape II. They have two flagella, short and a long one. Each flagellum arises from a basal granule III. They are connecting link between plants and animals Which of the following group is referred here?
A) Euglenoids
B) Diatoms
C) Slime moulds
D) Protozoans
Explanation
Euglenoids are unicellular flagellate protists. They are without cellulosic cell wall. The body is covered by thin and flexible pellicle. The pellicle is composed of fibrous elastin protein, small amount of lipid or/and carbohydrates. The euglenoids have two flagella, usually one long and one short. Each flagellum arises from a basal granule (blepharoplast). The flagella bear hairs (=tinsels). They are photosynthetic in the presence of sunlight. They are considered as connecting link between plants and animals
