- cleistogamy
- xenogamy
- chasmogamy
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
In xenogamy, transfer of pollen grains from anther to the stigma of a different plant occurs. This is the only type of pollination, which brings genetically different types of pollen grains to the stigma.

Top Questions on Double Fertilisation
- Assertion: Insects are important pollinators for many flowering plants. Reasoning: Insects visit flowers to obtain nectar or pollen, and in the process, they inadvertently transfer pollen from one flower to another, facilitating cross-pollination.

Concepts Used:
Pollination and Double Fertilization
Pollination is defined as the pre-fertilization event or process, where pollen grains from another are transferred to the stigma of a flower.
Double fertilization is a complex process that involves the fusion of one female gametophyte with two male gametes.
Types of Pollination:
All plants having flowers completely rely on the pollination method for reproduction. There are 2 types of pollination –
- Self Pollination
- Cross-Pollination
The end products of double fertilization are:
- Diploid Zygote
- Primary Endosperm Nucleus
