12 Major Difference between Self-Pollination and Cross-Pollination is today’s topic of this article. We will also discuss similarities between both types of pollination. we will compare all the important characters (Cross-Pollination vs. Self-Pollination) of Self-Pollination and Cross-Pollination.
Every medical entrance test always has some questions from the topic of the Difference between Self-Pollination and Cross-Pollination. So now this is very necessary to read all the differences and similarities between both types of pollination in the plants.
Major Difference between Self-Pollination and Cross-Pollination
Difference between Self-Pollination and Cross-Pollination
1. Self-pollination occurs between male and female flowers of the same plant whereas Cross-pollination occurs between male and female flowers of two plants of same species.
2. Self-pollination occurs in the Monoecious plants, whereas For Cross-pollination is not necessary for plants to be monoecious, because self-pollination generally takes place in Dioecious plants.
3. Because Self-pollination takes place between the male and female flowers of the same plant, it is not necessary to have a beautiful, large and Crispy flowers, whereas for the self-pollination it is very necessary to have beautiful, large and Crispy flowers. The reason behind this is very simple, Cross-pollination takes place in between two plants which require an agent to drop pollen grains to the female sex organ of another plant. so if the flower will not have these specialities, Agents like birds and insects will not be attracted towards flowers and pollination will not be done.
4. Fewer pollen grains are required for self-pollination. Because pollination is not wasted in this types of pollination, whereas a large number of pollen grains are required for cross-pollination, because pollen grains are destroyed in very large quantities in the case of cross-pollination.
Process of Self-Pollination
5. After self-pollination, the seeds are less in number, weight and smaller in size, while the seeds formed from cross-pollination are heavier in weight and are much larger in size.
6. If the process of self-pollination continues over generations, the plants start getting sick and weak, but if the cross-pollination continues for generations, the plants become strong and healthy.
7. Plants formed after self-pollination have fewer chances of being optimized according to the environment, while plants are optimized according to the environment after cross-pollination.
8. There is no possibility of development of different characters in self-pollination because plants have the same genetic properties, whereas, on the mixing of genetic traits of two plants in cross-pollination, there are more possibilities of development of variations and differences.
9. The purity of characters remains in plants formed after self-pollination, but after cross-pollination, there is no purity of traits over the period of generations.
10. There is no need of any agent like insect, bird, animal etc for self-pollination because it occurs between two male and female flowers of the same plant, whereas in the cross-pollination there is the need of these agents because cross-pollination occurs between male and female flowers of different plants of the same species.
11. Birds and insects have no role in self-pollination, whereas they have a lot of role in cross-pollination.
Similarities between Self-pollination and Cross-pollination
Similarities between Self-pollination and Cross-pollination
1. In both the process of Self-pollination and Cross-pollination involved with the male and female part of the flowers of the plants.
2. In both pollination methods, ( Self-pollination and Cross-pollination ) the pollen grains will germinate on the stigma of the female sexual organ, and the nuclei are transferred into the ovary to develop the embryo.
3. Another similarity between Self-pollination and Cross-pollination is that in both cases of pollination, the male nuclei will fertilize the female gametes ovule.
4. Both Self-pollination and Cross-pollination will result in the development of the embryo
Another similarity between Self-pollination and Cross-pollination is that both will eventually develop into new plants.
5. In both cases of Self-pollination and Cross-pollination, will only involve with plants of the same species.
Self-pollination takes place in only a plant where male and female parts of the flower get involved to develop a new plant. But in Cross-pollination two different plants of same species involved where female and male parts of different plants play further process to develop a new plant.
As the environment is getting changed day by day because of the different activities of human. There are so many harmful human activities. So the survival of all types of plants is very difficult. Due to human activities, different types of Pollution is increasing day by day.
In such condition, those plants are able to survive which are borne by cross-pollination. In Cross-pollination, chances of adaption are very high. but in the self-pollination adaption is not occur. so that many species are getting extinct.
This is true that purity of trait is maintained in self-pollination but it is of no use if the plant is not able to survive in changed environmental conditions. as Darwin theory already says that nature chooses best for the survival.
