AI-generated practice question — model-generated for extra practice, not a previous-year CBSE board question.
Pollen grains are produced in the anther (male part) of the stamen. They are transferred to the stigma (top of pistil) by agents like wind, water, or animals — this is called pollination.
After landing on the stigma, a pollen tube grows out of the pollen grain and travels through the style to reach the ovary. Here, the male germ-cell fuses with the egg cell present in the ovule. This fusion is called fertilisation, and it results in the formation of a zygote.

Examiners look for these key steps in sequence: pollen production in anther → pollination (transfer to stigma) → pollen tube growth through style → fertilisation in ovule → zygote. Use the correct terms — anther, stigma, style, ovary, ovule, fertilisation, zygote — as they carry marks. Don't confuse ovary with ovule; the ovule is inside the ovary and contains the egg cell.
