Question 10
The correct sequence of reproductive stages seen in flowering plants is

(a) gametes, zygote, embryo, seedling
(b) zygote, gametes, embryo, seedling
(c) seedling, embryo, zygote, gametes
(d) gametes, embryo, zygote, seedling

(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.
