Question

Mitotic cell division is required for

• A. Some single-celled organisms to reproduce sexually
• B. A single celled zygote to develop into a multicellular organism
• C. To repair cells in the G${}_0$ phase
• D. Both B and C

Answer 1

Answer: (D)

Both B and C

G${}_0$ phase is the phase where the cell ceases to divide as temporarily as in skin cells or permanently as in cells of the brain or cornea or the heart.

So as and when required the cells can revert back to division phase. A zygote also undergoes mitotic division to produce multi cellular organism.

So, the correct answer is 'Both B and C'
