Answers
Explanation:
There are two types of pollination, namely, cross- and self-pollination. In cross-pollination, pollen grains are transferred from the anther to the sigma of a different plant. Cross-pollination when followed by fertilization leads to the production offspring with heterosis or hybrid vigor.
Pollination is the process that helps to unite the male and female gametes and thus helps in fertilization. It can be broadly classified into two, cross-pollination and self-pollination and this is achieved with the help of a variety of vectors/agents. For successful pollinations, it must occur between the same species.
Types of Self-pollination and Cross-pollination:
Pollinations can occur either within a flower or between flowers of the same plant or flowers of different plants. Depending on this, pollinations are of three types, namely:
- Autogamy
- Geitonogamy
- Xenogamy
What are the Pollinating Agents?
The agents which are involved in transferring the pollen grains from one flower to another flower are called as the Pollinating Agents. Animals, birds, insects, wind and other biotic and abiotic agents are all examples of Pollinating Agents.
