Solution 1:<\/strong><\/span>
\nPollination is the transfer of pollen grains from the anther to the stigma of the same or another flower.
\nThe male gametes are produced inside pollen grains located in the anthers of androecium whereas the female gametes are produced in the ovules located in the ovary of gynoecium. For forming zygote, the male gametes need to be transferred to the gynoecium for fusing with the female gametes. This is achieved through pollination. Pollination occurs through insects, wind or other agents.
\nThere are two types of pollination – Self pollination and cross pollination.<\/strong><\/p>\n

Solution 2:<\/strong><\/span>
\nThe two modes of pollination are:<\/p>\n

(i) Self-pollination<\/strong> – It is the transfer of pollens produced within the anther of a flower to the stigma of the same flower or to the stigma of another flower of the same plant. In such flowers, pollination is ensured since the flowers bear similar genetic characters. Self pollination can occur in bisexual or monoecious flowers. Examples of plants showing self pollination are Mirabilis, Arachis etc.
\n(ii) Cross pollination<\/strong> – It is the transfer of pollen grains from the anthers of a flower of one plant to the stigma of a flower of another plant. Cross pollination occurs in unisexual or dioecious flowers such as papaya, maize, jasmine, rose etc.<\/p>\n
