how many types of pollination are there? explain with example?
Answers
Answer:
Pollination takes two forms: self-pollination and cross-pollination
The Joshua tree has a unique insect-pollinator, the yucca moth.
The bumblebee pollinates the morning glory in the cool beginnings of a new day.
And a gentle breeze is responsible for spreading the pollen of the spruce tree.
Tracey and I have learned that the moth, bee, and wind all act as pollinators for these plants. They are responsible for getting the pollen from the male part of the flower to the female part so that pollination can occur and a seed will form.
Although there are many different types of pollinators, there are just two main types of pollination—self-pollination and cross-pollination.
And today, we are having Summer come back to share a bit about pollination along with a summer science activity for you to enjoySELF-POLLINATION
In self-pollination, the pollen from the anther of a flower is transferred to the stigma of the same flower or the stigma of a different flower on the same plant. Then, pollination occurs and a seed is able to form.
This transfer can happen when the pollen grains literally spill onto the stigma, or the transfer can occur with the aid of a pollinator, like an insect, wind, or water.
The flowers of plants that use self-pollination to reproduce are generally much smaller.
CROSS-POLLINATION
In cross-pollination, the pollen from the anther of a flower on one plant is transferred to the stigma of the flower on another plant of the same species. Then, pollination occurs and a seed is able to form.
This transfer happens when the pollen is moved by an insect, by water, or by the wind. This type of pollination requires that there are two plants of the same variety in the area.
The flowers of plants that use cross-pollination are generally larger. The blooms also usually have a stigma that is taller than the stamens, which gives more of a chance for the pollen to spread to other flowers.
