Depending on the type of pollinators, the pollen grains may be sticky or light.
Exine present on the pollen grains as the outermost covering layer is contributed by the tapetum cells. Reaching on the stigma after pollination, the stigmatic cells interact with the material of exine to determine the compatibility of the pollen to allow its germination for fertilization.
The top of the stigma is sticky and is where the pollen attaches to it.

becouse i think its stuiped!
Pollination is a process of transfer of pollen grains from the anther of a stamen to the stigma of a carpel . Agent that helps in pollination are wind, insects, birds and water.
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.
yes, but it is the anther to the stigma of a different plant self pollination is the transfer of pollen from the anther to the stigma of the same plant
It takes from a few minutes to few hours depending upon the type of flower and the pollinators.

Pollination occurs when the pollens from the anther of a flower is transferred to the stigma of the same or another flower. This is of two types- Self-Pollination(when the pollens from the anther of a flower are transferred to the stigma of the same flower or plant) and Cross-Pollination( when it gets transferred to the stigma of flower on another plant). Pollination is brought about by the help of various factors like insects, birds,wind, water.
Most pollination takes place with the help of insects and wind. The purpose of pollination is to transmit the pollen from one plant to the stigma of another plant.
The two main types of pollination are self (or autogamous) pollination and cross (or heterogamous) pollination. Self pollination - is when pollination is tansfer from the anther to the stigma of the same flower. Cross pollintion - is when pollination is transfer from the anther to the stigma of another flower
