Which cells do not form a layer and remain structurally separate : -
A
Epithelial cells
B
Muscle cells
C
Nerve cells
D
Gland cells
Detailed Solution
Epithelial and gland cells are packed closely into layers, and muscle cells form bundles and sheets.
Nerve cells (neurons) are structurally separate units. They do not form a continuous layer, and they are not even in direct cytoplasmic contact with each other; they communicate across synapses (small gaps).
So nerve cells do not form a layer and remain structurally separate.
