Identify the INCORRECT pair of cell shape types and their examples.
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. Oblong – Nerve cells.
Nerve cells are not oblong; they have a highly irregular and elongated shape with long extensions called axons and dendrites that help in transmitting signals over long distances. Oblong refers to a more uniformly elongated shape with rounded ends, which does not accurately describe nerve cells.
Correct pairs:
Oval – Chlamydomonas: A unicellular alga that is oval-shaped.
Elongated – Muscle cells: Muscle cells are long and thread-like, suited for contraction.
Irregular – Amoeba: Amoeba has no definite shape, making it irregular.
Thus, "Oblong – Nerve cells" is the mismatch.
