If each carpel in an onion flower contains 40 ovules. What is the maximum number of reduction divisions occurring in the ovary?
120
No. of ovules = no. of reduction divisions.
No. of ovules present in the ovary of onion = 40 × 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.
