rite
sexual reproduction
(a) Formation
of pollen tube
(b) pollination
(c) Formation
of zygot
(d) formation of embryo
(e) formation of endosperm
Answers
Explanation:
Sequence of events in reproduction in flowers:
(1) Pollination - It is the process by which pollen transferred from anther and stigma.
(2) Fertilization - Is the process of fusion of male and female gamete. Once the pollen tube enter into synergid male gametes released. One of male gamete fuses with egg and form diploid cell zygote and this is called as syngamy. Other male gamete fuses with two polar nuclei to form endosperm and this is called as triple fusion because of fusion of three haploid nuclei. The whole process is called double fertilization.
(3) Embryo formation - Development of embryo from zygote.
(4) Seedling - Seed enclose embryo and covered by seed coat.
Therefore, the correct answer is option C.
