In cross pollination there is wastage of pollen grains , but in self pollination there is no wastage of pollen grains.
What happens when pollen is moved from the anthers to the stigma?
Pollen grains contain the male gamete (sex cell).
Does pollination occurs when pollen grains land on the sticky surface of the anther?
No, pollination occurs when pollen grains land on the sticky surface of the stigma.
What happens when the pollen grain falls on the stigma?
when pollen grains falls on stigma, it creates a pollen tube which dilivers pollen grain and fuses with female gametes present in the ovule
Are pollen grains formed within the stigma?
It could be done by animal pollination , wind pollination or even self pollination.
How are more pollen grains important in terms of reproductive success?
More pollen grains increase the chances of successful pollination. Successful pollination refers to pollen grains falling on the correct stigma for reproduction to occur.
What is the difference 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.
Pollen grains move from a flower's stamen to it's pistil during what?
During self pollination, pollen grains move from the stamen of a flower to its pistil. Cross pollination involves flowers from different plants.
What is it called when pollen moves from the anther to the stigma?
The transfer of pollen grains from the stamen to the pistil is called pollination.
What is the transfer of pollen from the anther to the stigma called?
Pollen grains are transferred to the stigma of a flower during pollination. This process is usually completed by bees.
What aids in the pollination of plants by transferring pollen grain?
The wind aids in pollination when plants transfer pollen grains. Insects can also help in the transferring of pollen grains.
