Biology Question on sexual reproduction in flowering plants
Endosperm is formed during the double fertilization by:
A
Two polar nuclei & one male gamete
B
One polar nuclei & one male gamete
C
Ovum and male gamete
D
Two polar nuclei & two male gametes
Answer
Two polar nuclei & one male gamete
Explanation
Solution
Double fertilization is a characteristic event observed in angiosperms, wherein both the embryo and the endosperm are formed simultaneously. In this process, a male gamete combines with two polar nuclei, giving rise to a triploid nucleus, which subsequently matures to create the endosperm.
So, the correct option is (A): Two polar nuclei & one male gamete
