Self pollination-
- The transfer of pollen from a male reproductive structure (an anther or male cone) to a female reproductive structure (a stigma or female cone) of the same plant or of the same flower.
- Self-pollination tends to decrease the genetic diversity (increase the number of homozygous individuals) in a population, and is much less common than cross-fertilization. Many species of plants have evolved mechanisms to promote cross-pollination and avoid self-pollination, though certain plants, such as the pea, regularly self-pollinate.
Cross pollination-
- The transfer of pollen from the male reproductive organ (an anther or a male cone) of one plant to the female reproductive organ (a stigma or a female cone) of another plant.
- Most plants reproduce by cross-pollination, which increases the genetic diversity of a population (increases the number of heterozygous individuals). Mechanisms that promote cross-pollination include having male flowers on one plant and female flowers on another, having pollen mature before the stigmas on the same plant are chemically receptive to being pollinated, and having anatomical arrangements (such as stigmas that are taller than anthers) that make self-pollination less likely. Insects and wind are the main agents of cross-pollination.

How is self-pollination and cross-pollination alike?
Both self-pollination and cross-pollination are methods of transferring pollen from the male reproductive organs of a flower to the female reproductive organs. This process is essential for plant reproduction and the production of seeds. The main difference between the two methods is that self-pollination occurs within the same flower or plant, while cross-pollination involves the transfer of pollen between different flowers or plants.
What are the three ways in which pollination can occur?
Pollination can occur through wind, animals (such as bees, butterflies, and birds), and self-pollination (where pollen is transferred from the anther to the stigma of the same flower or a different flower on the same plant).
When a pea plant pollinates itself the process is called?
Cross pollination is where the pollen in one plant is used to pollinate those eggs that are available in a different plant. It fosters the vegetation process in Flora.
Why is self pollination better than cross pollination?
Cross pollination results in hybrid seed formation. Hybrids in general are vigorous than self pollinated plants due to additive gene action.
What type of pollination in hibiscus?
Hibiscus plants can be both self-pollinating and cross-pollinating. They are primarily pollinated by bees, butterflies, and hummingbirds, who transfer pollen between flowers as they feed on nectar. Hibiscus flowers can self-pollinate when the pollen from the anther is transferred to the stigma within the same flower.
What is Different between self pollination and cross pollination?
In cross pollination there is wastage of pollen grains , but in self pollination there is no wastage of pollen grains.
What are the types of pollination?
cross and self pollination
Distinguish between self-pollination cross-pollination?
The process of pollination from same flower is called self-pollination. the process of pollination from another flower of same breed is called cross-pollination.
What are the 2 different methods of pollination?
The two main types of pollination are self (or autogamous) pollination and cross (or heterogamous) pollination. Self pollination - is when pollination is tansfer from the anther to the stigma of the same flower. Cross pollintion - is when pollination is transfer from the anther to the stigma of another flower
What are the three types of pollination?
self-pollination cross-pollination wind-pollination
What are two types of pollination?
what is vegetable and its reproductive part
What are the two types of pollinator?
The two main types of pollination are self (or autogamous) pollination and cross (or heterogamous) pollination. Self pollination - is when pollination is tansfer from the anther to the stigma of the same flower. Cross pollintion - is when pollination is transfer from the anther to the stigma of another flower
What is the difference from self and cross pollination?
Cross pollination is when the wind or a insect carries pollen from one flower to another. Self pollination is when a flower produces pollen and uses it in asexual reproduction.
What happens during the processes of cross-pollination and self-pollination?
there is not to big of a differents
Can someone help me use pollination self-pollination and cross-pollination in the same sentence?
Self pollination is when a flower pollinates itself with its own pollen and cross pollination is when a flower uses another flower's pollen.
What is the name of the transfer of pollen from the stamina to the pistil?
pollination; if it from the same plant (self-fertilization; self-pollination); pollen from one plant to the stigma of another plant (cross-pollination; cross-fertilization)
How many types of pollination are there?
There are two main types of pollination: self-pollination, where the pollen is transferred from the anther to the stigma of the same plant, and cross-pollination, where the pollen is transferred between two plants of the same species.
