Question

Read carefully the following statements about sexual fertilisation in angiosperms.
(i) Pollen tube carries the male gamete towards archegonia and discharge contents in the mouth of archegonium.
(ii) A zygote is obtained when a male gamete fuses with egg.
(iii) Zygote develops into embryo and embryo into seeds.
(iv) The seeds so obtained are naked.
Which of the statement given above are correct?

• A. (i) and (ii) only
• B. (i), (ii) and (iv)
• C. Only (ii) and (iii)

Answer 1

Answer: (C)

Once the pollen grain is released from microsporangium it is carried with the help of air current to the opening of ovules. On entering an ovule, male gamete fuses with egg to give rise to zygote. Zygote develops into embryo and embryo into seeds. In angiosperm, archegonium is absent
