Cross pollination is when the wind or a insect carries pollen from one flower to another. Self pollination is when a flower produces pollen and uses it in asexual reproduction.
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
The process of pollination from same flower is called self-pollination. the process of pollination from another flower of same breed is called cross-pollination.
self-pollination cross-pollination wind-pollination
Pollination can occur through wind, animals (such as bees, butterflies, and birds), and self-pollination (where pollen is transferred from the anther to the stigma of the same flower or a different flower on the same plant).
In cross pollination there is wastage of pollen grains , but in self pollination there is no wastage of pollen grains.
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.
Self pollination is when a flower pollinates itself with its own pollen and cross pollination is when a flower uses another flower's pollen.
Cross pollination happens when the pollen of one flower is placed upon the stigma of another flower, whether of the same varietyor not.

During self pollination, pollen grains move from the stamen of a flower to its pistil. Cross pollination involves flowers from different plants.
