Concept:In flowering plants, the female gamete is present inside the ovule located in the ovary, not on the stigma.
Explanation:Option A is correct: The anther produces pollen grains, and each pollen grain contains male germ-cells.
Option B is incorrect: The stigma is the receptive tip of the pistil that only catches pollen during pollination.
The female gamete, or egg cell, is found inside the ovule, which is enclosed within the ovary of the flower.
Option C is correct: The fusion of male and female gametes during fertilisation produces a zygote.
Option D is correct: The fusion of a male gamete with a female gamete is defined as fertilisation.
Thus, the only false statement is that the female gamete is present in the stigma.
Answer:Option B — "Female gamete is present in the stigma" is the incorrect statement.
