Question

Pollination is a characteristic of

• A. Angiosperms
• B. Pteridophytes
• C. Bryophytes
• D. All of the above

Answer 1

Answer: (A)

Pollination is the characteristics of flowering plants i.e., angiosperms. After the pollen tube reaches the ovary, the process of double fertilization occurs in the angiosperms. One of the male gamete fuses with the egg cell (syngamy) which results in the formation of zygote. The second male gamete fuses with two polar nuclei to form a triploid, primary endosperm nucleus (PEN). This is called triple fusion. Since two fusion syngamy and triple fusion take place in an embryo sac, it is called double fertilisation. Central cell and PEN develops into the endosperm and zygote develops into the embryo.

So, the correct answer is option A.
