Pollen is male part of the flower and stigma is the uppermost part of the gynoecium (which is female part). Thus stigma does not produce pollen, rather pollen land on stigma after pollination to fertilize the egg inside the ovary of the flower.
yes
no
In a flower carpel, the stigma is the terminal portion that has no epidermis and is fitted to receive pollen.
The anther produces pollen grains which would be transferred to other plant's stigma which will receive the pollen grains when an insect fly pass it then the pollen grains will be stuck on its wings.
Self pollination is the dropping of pollen on the stigma of the same flower that produced the pollen, thereby pollinating the flower.
The stamens which are the male parts produce pollen. It creates in the anther. For an even better answer if the pollen from a stamen travels to the stigma in the same flower it will be know a self pollination. For cross pollination the anther must produce pollen and travel to a different flower's stigma. It is basically self pollination with two flowers.
The pollen grains cannot fertilize the flower
Flowers are the reproductive parts of the flower. The male parts produce pollen and the egg takes in the pollen and creates seed.
when pollen grain are transferred from the stigma the ovule of the flower , whats takes place
That is called the stigma.
the middle of the flower holds pollen or wear it is yellow
There are two parts of a flower that produces pollen. The two parts are the stalk and the top of the flower.
Self pollination is when the pollen from the Stamen goes to the Stigma of the same flower, rather then the pollen going to a Stigma of a different flower.
no, the anther produces pollen
