Selcted the INCORRECT statement.
Female gamete is present in the stigma.
The correct answer is Option 2 i.e. Female gamete is present in the stigma.
In flowering plants, the female gamete (also called the egg cell) is located inside the ovule, which lies within the ovary — the swollen base of the pistil. The stigma, on the other hand, is the sticky top part of the pistil that receives pollen grains during pollination. After pollination, the pollen grain grows a pollen tube down through the style to reach the ovule, where the male gamete fuses with the female gamete — a process called fertilisation. Therefore, stating that the female gamete is present in the stigma is incorrect.
