Question

If each carpel in an onion flower contains 40 ovules. What is the maximum number of reduction divisions occurring in the ovary?

• A. 40
• B. 80
• C. 120
• D. 60

Answer 1

The correct option is C

120

No. of ovules = no. of reduction divisions.
No. of ovules present in the ovary of onion = 40 $\times$ 3 = 120. Since, onion flowers have a tricarpellary ovary.
Therefore, the total no. of reduction divisions occurring in the ovary of an onion flower is 120.
