Endosperm is formed during the double fertilization by:
- Two polar nuclei & one male gamete
- One polar nuclei & one male gamete
- Ovum and male gamete
- Two polar nuclei & two male gametes
The Correct Option is A
Solution and Explanation
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

- Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R.
Assertion A : The potential (V) at any axial point, at 2 m distance(r) from the centre of the dipole of dipole moment vector \(\vec{P}\) of magnitude, 4 × 10-6 C m, is ± 9 × 103 V.
(Take \(\frac{1}{4\pi\epsilon_0}=9\times10^9\) SI units)
Reason R : \(V=±\frac{2P}{4\pi \epsilon_0r^2}\), where r is the distance of any axial point, situated at 2 m from the centre of the dipole.

Sexual Reproduction in Flowering Plants
Sexual reproduction in flowering plants takes place or happens when the production of a new organism occurs from two parents by making use of their gametes or sex cells. Both sexual and asexual reproduction can be found in plants. Nearly all flowering plants reproduce sexually. Flowers play a captious role in the process as it carries both the male and female reproductive parts commonly known as androecium and gynoecium respectively.
An individual flower comprises the following parts -
- Pedicle
- Calyx
- Petals
- Sepals
- Stamen
- Pistil
- Receptacle
