Organisms reproduce offspring. This is complicated by the fact that there are other factors at play. Pollination is the most prevalent way for plants to communicate with each other. Pollination refers to the pre-fertilization events in which pollen grains from an anther are transported to a flower’s stigma.
Plants, as we know, do not move. They are unable to form a friendship with one another on their own. For this, they’ll need agents. Pollination occurs next, which aids in the union of two gametes, i.e., female and male, as well as fertilisation. Self-pollination and cross-pollination are two types of pollination that can be achieved by a variety of agents.
Types of Pollination
Pollination can take two forms:
1 Self Pollination
2 Cross-Pollination
Self Pollination
Pollen is carried from a flower’s anthers to the stigma of another flower, resulting in self-pollination. This type of pollination is commonly used by hermaphrodite or dioecious plants, which have male and female sexual components on the same flower. Pollination in self-pollinating plants is less reliant on external inputs. These plants require frequent visits from the wind or other small insects in order to survive. Pollen transfer is aided by the anthers and stigma of self-pollinating flowers having similar lengths. There are two types of self-pollination: In self-pollination, pollen is transferred from one bloom’s anthers to the stigma of another.
Benefits to self-pollination
Self-pollination has several benefits:
- Cross-pollination results in less pollen grain wastage
- There is no genetic diversity, resulting in self-pollination that finally balances out the race
- No money is spent on external forces such as wind or water
- Because they produce a small amount of pollen grain, self-pollination gives a high percentage of pollination success
Downsides to self-pollination
There are some downsides to self-pollination:
- The race’s energy and stability are no longer present
- In the subsequent generation, the protection against infection is reduced
Cross-Pollination
This type of pollination involves pollen being transferred from the anthers of one bloom to the stigma of another. In this circumstance, the two flowers are genetically different. The presence of another agent to transfer pollen is required for cross-pollination to occur. Birds, animals, water, wind, and insects all help to pollinate flowers. Depending on the pollination agent, cross-pollination can take various different forms, including Hydrophilous flowers that rely on water for pollination. Because the flowers are small and inconspicuous, other agents are often ignorant of them. Their petals aren’t particularly fragrant or colourful. Pollen has been altered such that it may float on water.
Benefits to Cross pollination
Cross pollination has several benefits:
- Through cross-pollination, unisexual plants can reproduce
- As a result of genetic recombination, recessive characteristics in the ancestry are lost
- This approach boosts the immune system of the offspring and maintains them healthy
- As fertilisation happens between two separate genes, this process also generates new genes in the species cycle
Downsides to Cross pollination
There are some downsides to Cross pollination:
- There is a lot of pollen grain waste throughout this operation
- There’s a danger that during meiosis, beneficial attributes will be lost and harmful traits will be added to kids
Conclusion
We came to the conclusion that pollination is important since it leads to the production of edible fruits and seeds, which in turn leads to the establishment of new plants. The first phase in pollination is flower pollination. Pollination can be divided into two types, each of which can be achieved by different methods. Self-pollination and cross pollination are the two methods.
