Fertilisation and Post-Fertilisation Events

Begin with pollen on stigma, trace male gamete to ovule, write fusion, then state zygote, embryo, seed, and fruit formation.

Show pollen tube reaching the ovule, then a simple post-fertilisation flow from ovule to seed and ovary to fruit.

Writing that stigma becomes seed is wrong because stigma receives pollen but the ovule forms the seed.

Fertilisation is the fusion of male and female gametes to form a zygote; after fertilisation, the ovule develops into a seed and the ovary develops into a fruit.

Fertilisation is the fusion of male and female gametes to form a zygote; after fertilisation, the ovule develops into a seed and the ovary develops into a fruit. Male gamete plus female gamete gives zygote; fertilised ovule becomes seed; ovary becomes fruit. In mango, the fleshy fruit develops from the ovary, while the seed develops from the fertilised ovule.

After pollination, the male gamete reaches the ovule. The male and female gametes fuse to form a zygote. The zygote develops into an embryo. The ovule becomes the seed, and the ovary becomes the fruit. These changes help protect and disperse the next generation. Male gamete plus female gamete gives zygote; fertilised ovule becomes seed; ovary becomes fruit. If a labelled diagram asks what structure becomes a seed, identify the ovule, because the fertilised ovule develops into the seed. Questions ask for the sequence after pollination, the fate of ovule and ovary, and zygote formation. Writing that stigma becomes seed is wrong because stigma receives pollen but the ovule forms the seed.
