Euglenoids: Key Features — NEET Biology

Correct answer: D — A-ii, B-i, C-iii, D-iv, E-v

The question tests the ability to recall and associate specific characteristic features with different groups of Protista. A. Chrysophytes: Possess indestructible siliceous cell walls and float passively as plankton (ii). They are the chief producers in oceans. B. Dinoflagellates: Most have two flagella, one longitudinal and the other transverse in a furrow between stiff cellulose wall plates (i). C. Euglenoids: Have a protein-rich pellicle instead of a cell wall, making their body flexible, and exhibit mixotrophic nutrition (iii). D. Slime Moulds: Are saprophytic protists that form fruiting bodies bearing spores with true walls during unfavourable conditions (iv). E. Ciliated Protozoans: Characterized by thousands of cilia for movement and a gullet to steer food into the cell (v). Therefore, the correct match is A-ii, B-i, C-iii, D-iv, E-v.
