After pollination, the pollen grains germinate on the stigma and grow a pollen tube down the style to reach the ovule. The pollen tube delivers sperm cells to fertilize the egg cell within the ovule, leading to the formation of a seed.
No, pollination occurs when pollen grains land on the sticky surface of the stigma.
Pollination
The transfer of pollen grains from the stamen to the pistil is called pollination.
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.
Pollination is a proces of dispersing pollen grains to stigma and the fertilization is the followed proces of pollination.
In cross pollination there is wastage of pollen grains , but in self pollination there is no wastage of pollen grains.
No, pollination occurs when pollen grains land on the sticky surface of the stigma.
Pollination
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.
Out of hundreds and thousands of pollen grains produced by each flower a few land on the stigma during pollination and others just wither away.
In cross pollination there is wastage of pollen grains , but in self pollination there is no wastage of pollen grains.
The anther is the part of the stamen that contains the pollen grains. These pollen grains are the male reproductive cells that are essential for the process of pollination.
During self pollination, pollen grains move from the stamen of a flower to its pistil. Cross pollination involves flowers from different plants.
The transfer of pollen grains from the stamen to the pistil is called 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.
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 germination starts on compatible stigma
