Choose the wrong statement.
Male germ-cells are produced by pollen grain.
Female gamete is present in the stigma.
Fertilisation gives us zygote.
The fusion of male gamete and female gamete is known as fertilisation.
Female gamete is present in the stigma.
In angiosperms (flowering plants), the male gametes are produced inside the pollen grains, and fertilisation takes place inside the ovule located within the ovary. The stigma is the receptive surface at the top of the carpel/pistil where pollen grains land during pollination, not where the female gamete is present. Therefore, the statement 'Female gamete is present in the stigma' is INCORRECT.

Therefore, the statement 'Female gamete is present in the stigma' is INCORRECT.
Think of the stigma as the landing pad (helipad) on a roof where pollen arrives, while the female gamete (egg) is safely secured inside the master control room (ovary/ovule) deep inside the building.
Pollen lands on STIGMA, but egg lives in OVULE.

In plant sexual reproduction, the anther produces pollen grains which contain male germ-cells (male gametes). The female gamete (egg cell) is housed within the embryo sac inside the ovule, which is situated deep inside the ovary, not on the stigma. When pollen lands on the stigma, it germinates and grows a pollen tube down the style to deliver the male gametes to the ovule for fertilisation.
Pollen grains are produced by the anther in the stamen.
The stigma receives pollen grains during pollination.
The female gamete (egg cell) resides inside the ovule within the ovary.
Fertilization results in the formation of a zygote, which develops into an embryo.
Ensures genetic variation through sexual reproduction in plants.
Crop breeding and agriculture
Horticulture and plant propagation
Option A is correct because pollen grains produce male germ-cells.
Option C is correct because fertilisation of male and female gametes produces a zygote.
Option D is correct because the fusion of male and female gametes is defined as fertilisation.
B is correct тАФ Female gamete is present in the ovule (inside the ovary), not in the stigma, making statement B incorrect.
In competitive exams like RRB and SSC, always distinguish between the site of pollination (stigma) and the site of fertilisation/female gamete storage (ovary/ovule).
