(a) Define fertilisation.
(b) What happens to Zygote, Ovule, Ovary and Stamens after fertilisation in a flowering plant?
Official answer
(a) Fertilisation is the fusion of the male and female gametes to form a zygote.
(b) After fertilisation, the zygote develops into an embryo inside the ovule. The ovule develops into a seed. The ovary develops into a fruit, which is the ripened ovary that contains seeds. The stamens wither and fall off after fertilisation.

Quick oral answer
Fertilisation is the process by which the male and female gametes fuse to form a zygote. After fertilisation, the zygote develops into an embryo inside the ovule, which eventually forms a seed. The ovary develops into a fruit, which contains seeds. The stamens wither and fall off after fertilisation.
Common mistakes
- 1.confusing fertilisation with pollination
- 2.not explaining the changes in the ovary and stamens
Analysis and explanation
This question requires the student to recall the definition of fertilisation and explain the changes that occur in the zygote, ovule, ovary, and stamens after fertilisation in a flowering plant. The student should be able to describe the process of fertilisation and the subsequent development of the zygote, ovule, and ovary.
Interesting facts
Fertilisation is a critical step in the reproduction of flowering plants.
The zygote develops into an embryo, which eventually forms a seed.
