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
Answer: A
Solution: The process of reproduction is divided into different stages. The first stage is the production of male and female gamete i.e., pollen and ovule respectively. The pollen grain reaches the stigma of flower by the process of pollination. The pollen germinates and forms pollen tube that reaches to the ovary and then male gamete is released. Male gamete fuses with female gamete and results in the formation of zygote.
The zygote divides several times to form an embryo. Then, there is seed development. Flowering plant's seeds have three parts, embryo formed from zygote, endosperm formed by double fertilization and seed coat formed by maternal tissue of ovule. The seeds under favorable conditions, germinate to produce a seedling.
