Question

A teacher focussed the slide under a compound microscope. Which student identified it correctly?

• A. Sheela identified it as cheek cells.
• B. Madhu identified it as squamous epithelium.
• C. Balaji identified it as parenchyma.
• D. Shanti identified it as onion peel.

Answer 1

The correct option is B Madhu identified it as squamous epithelium.

Given cells are polygonal in shape, tightly packed and possess centrally located nucleus.

1. Cheek cells are loosely packed and secrete mucus. Hence, option A is incorrect.
2. Parenchyma cells are loosely packed cells with large intercellular spaces. Hence, option C is incorrect.
3. Onion peel cells possess a cell wall, large vacuole, and nucleus located at the periphery. Hence, option D is incorrect.
4. Squamous epithelium cells are tightly packed, flat, polygonal cells. Animal cells possess a centrally located nucleus. Therefore, option B is correct.
