Fertilisation and Post-Fertilisation Events
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.
Practice This ConceptMain explanation
Teacher explanation
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.
Example
In mango, the fleshy fruit develops from the ovary, while the seed develops from the fertilised ovule.
Simple analogy
Ovule to seed, ovary to fruit.
Common confusion
Students often write that the whole flower becomes the fruit; more accurately, the ovary develops into the fruit.
Exam tip
For sequence questions, write pollination, pollen tube growth, fertilisation, zygote, embryo, seed, and fruit in order.
