\nThe question asks which pair about an organ\/part that helps in locomotion is *not* correctly matched.
\nA) Euglena: Flagellum – Correct. Euglena is a motile protozoan that uses a whip-like structure called a flagellum for propulsion.
\nB) Paramecium: Cilia – Correct. Paramecium is a motile protozoan covered in numerous short, hair-like structures called cilia, which it uses for movement and feeding.
\nC) Nereis: Pseudopodia – Incorrect. Nereis is a genus of marine polychaete worms. Polychaetes like Nereis use lateral, fleshy appendages called parapodia (often bearing bristles called chaetae) for locomotion (crawling, swimming) and respiration. Pseudopodia are temporary cytoplasmic extensions used for locomotion and feeding by some protozoans (like Amoeba) and certain cells in multicellular organisms. Nereis does not use pseudopodia for locomotion.
\nD) Starfish: Tubefeet – Correct. Starfish (sea stars) are echinoderms that use their tube feet, which are part of the water vascular system, for locomotion, grasping, and feeding.
\n<\/section>\n
\nDifferent organisms have evolved diverse structures for locomotion depending on their environment and body plan.
\n<\/section>\n
\nPseudopodia (“false feet”) are characteristic of amoeboid movement. Flagella and cilia are whip-like or hair-like structures used by many protists and some animal cells. Parapodia are characteristic appendages of polychaete worms. Tube feet are unique to echinoderms.
