What is the defference between self and cross pollination?
Self pollinationWhen pollen grains from a flower are carried to the stigma of the same flower or on the other flower of the same plant, the phenomenon is called self pollination.Cross pollinationWhen the pollen grains from a flower are carried to the stigma of the flower on other plant, the phenomenon is called cross pollination.
What is the male sex cells of a flower that can be carried by the wind?
The male sex cells of a flower that can be carried by the wind are pollen grains. These pollen grains are produced in the anthers of the flower and are dispersed by the wind to reach the female reproductive organs of other flowers for pollination.
When pollen lands on the stigma is this pollenination or fertilasatoin?
It is called as pollination. Here the pollen grains are transmitted from one flower to other flower. Pollen grains may be transmitted in the same flower from the stamen to stigma.
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 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.
Are pollen grains formed within the stigma?
No, pollen grains are not formed within the stigma. Pollen grains are formed in the anthers of a flower's stamen. The stigma is part of the female reproductive structure of a flower, where pollen grains land and germinate to fertilize the ovules.
What is the job of the anthor on the flower?
Anther provides pollen grains for pollination & fertilization
The transfering of pollen between plants is called?
the transfer of pollen grains is called pollination. I the transfer of pollen is from the anther to the stigma of the same plant it is known as self pollination, whereas if the transfer of pollen is from the anther of one flower to the filament of a different flower, it is termed as cross pollination
Which structure do pollen grains attach during pollination?
Pollen grains attach to the stigma of a flower's pistil during pollination. The stigma is the receptive part of the pistil where the pollen lands and germinates to form a pollen tube for fertilization to occur.
Where are pollen grains produced?
pollen grains are produced in pollen sac of anthers which are present on the male gamets of flower
What is the pollenation for on a flower?
Pollination is the transport of pollen from the anther onto the stigma of the flower. Pollination can be carried by insects, other animals and wind.
The portion of the flower containing pollen grains?
The portion of the flower containing pollen grains is the anther. The anther is located at the top of the flower's stamen and is responsible for producing and releasing pollen for the process of pollination.
