Question

_____ is the largest isolated single cell.

• A. Egg of Salamander
• B. Egg of an Ostrich
• C. Nerve cell
• D. Mesophyll cell

Answer 1

Answer: (B)

Cells differ significantly in size and activities. The shape of the cell depends on the functions performed by it.
For example -

• Eggs in Amphibians (Salamander) are released in masses and are smaller in size.
• Largest isolated single cell - the egg of an Ostrich.
• Nerve cells are some of the most elongate cells.

The mesophyll is the ground tissue enclosed between the upper epidermis and lower epidermis in leaf. It is parenchymatous.
