Which cell has changing shapes?
Smooth muscle
Nerve cell
Amoeba
Ovum
Amoeba
Amoeba is a single-celled organism that has no fixed shape. It constantly changes its shape by forming temporary projections called pseudopodia (false feet), which help in locomotion and capturing food.

Think of a water balloon filled with thick fluid; when you press on one side, the balloon bulges out in another direction, constantly altering its overall form.
A-M-O-E-B-A: Always Moving, Outward Extensions Body Alters.
The shifting of the cytoplasm inside the cell causes the cell membrane to push outward in different directions, forming pseudopodia. This amoeboid movement enables unicellular organisms like Amoeba to crawl and engulf food particles through phagocytosis.
Amoeba is a eukaryotic unicellular microorganism.
It uses pseudopodia for amoeboid movement and engulfing prey.
Smooth muscle cells are spindle-shaped, and nerve cells are elongated.
Ovum is generally spherical or ovoid in shape.
Ability to change shape allows Amoeba to squeeze through tight spaces and capture food easily.
Study of cellular locomotion, phagocytosis, and protoplasmic streaming in biology.
Option A (Smooth muscle) has spindle-shaped cells.
Option B (Nerve cell) has a fixed elongated structure with axons and dendrites.
Option D (Ovum) is typically round or spherical.
C is correct тАФ Amoeba has no fixed shape and constantly changes its shape using pseudopodia.
Always remember that while most multicellular organisms have cells with fixed, specialized shapes tailored to their functions, certain unicellular organisms like Amoeba and white blood cells (leukocytes) can alter their shape dynamically.
