Answer 1

Answer: (D)

A- IV B- III C-I D-II

• Siphonogamy is the type of fertilization which takes place by the formation of the pollen tube. Zoidogamy is the type of fertilization in which there are ciliated male gametes that take part in the process of fertilization. Both the type of fertilization occurs in Cycas.
• Gingko is called as the living fossil. These are non-flowering plants. They belong to the division Gingkophyta. They are the only plant which are alive in this division. There are fossils of this plant which are obtained as well as there are living plants of this species.
• Bryophytes are the plants that can live in the land and water. The animals which can live inland and water are called as amphibians and thus, bryophytes are referred to as amphibians in the plants. They are plants that require the water for the migration of the male gametophyte to the female gamete during sexual reproduction.
• Arachis is a group of flowering plants. These is the plants from the pea family. The fertilization in these plants is called as double fertilization. There is a fusion of the male and the female gamete which forms the zygote which develops to form the embryo. The other male gamete fuses with the secondary nuclei to form the endosperm.

Thus, the correct answer is option D.
