Question

How many mitotic divisions must occur in a cell of root tip to form 256 cells?

• A. 256
• B. 8
• C. 128
• D. 64

Answer 1

The correct option is B 8

The root tips of plants undergo mitosis. The number of mitotic divisions in the root tip can be calculated by the formula $(2{)}^n,$ where n is the number of mitotic divisions.
$(2{)}^n=256$
$(2{)}^8=256$
Hence 8 mitotic division.

Thus the correct answer is option B.
