Solution

(a) gametes, zygote, embryo, seedling

The reproduction in angiosperms starts with the formation of male and female gametes in anther and ovary respectively. Through pollination either by self-pollination or cross-pollination, fertilisation of gametes takes place to form a zygote. After fertilisation, the zygote divides several times to form an embryo within the ovule. The ovule develops a tough coat and is gradually converted into a seed. The ovary grows rapidly and ripens to form a fruit.
