The transport of pollen to the stigma of another flower of the same plant is known as geitonogamy.
Xenogamy is the transfer of pollen from one flower of a different plant to the stigma of another flower of a different plant of the same species.
Some of the advantages of self-pollination are
The race’s purity is maintained.
Pollen grains do not go to waste.
Recessive characters are deleted through self-pollination.
Pollination is not dependent on external causes or pollinating agents.
Some of the advantages of cross-pollination are:
The new plants are more nutritious.
New kinds are created as a result of cross-pollination.
The seeds are produced in greater quantities and have a higher viability rate.
The seeds mature and germinate correctly, resulting in healthier plants.
Cross-pollination can occur between two different types of the same species or even two separate species, resulting in new types.
Dichogamy refers to the state in which a flower’s male and female reproductive organs grow at distinct/different times, preventing self-fertilization. Hence it becomes easier for the plant to carry out cross pollination as the male and female parts do not mature at the same time.
Final Answer:
The transport of pollen to the stigma of another flower of the same plant is known as geitonogamy. Xenogamy is the transfer of pollen to a flower of a different plant but of the same species.
There are certain advantages of self-pollination. One of the advantages is that the purity of the race is maintained. Another advantage is that it is not dependent on any external agents which prevents wastage of pollen.
One of the advantages of cross pollination is that new plants are created which are more nutritious. The seeds produced have a higher viability rate and have a greater probability of producing healthier plants.
Dichogamy is a condition in which the male and female parts of the flower mature at different times. This prevents self pollination and forces the plant to go for cross pollination
