How does pollination take place by wind and water? Differentiate between self-pollination and cross-pollination
Answers
Answer:
In cross-pollination, both the stigma and anther mature at different times. ... Pollen grains are transferred directly to a flower's stigma. Pollen grains are carried via wind, insects, animals, water, etc.Self-pollination occurs when the pollen from the anther is deposited on the stigma of the same flower, or another flower on the same plant. Cross-pollination is the transfer of pollen from the anther of one flower to the stigma of another flower on a different individual of the same species.Pollen floats on the water's surface drifting until it contacts flowers. This is called surface hydrophily, but is relatively rare (only 2% of pollination is hydrophily). This water-aided pollination occurs in waterweeds and pondweeds. In a very few cases, pollen travels underwater.Pollination: Pollination is the process of transfer of pollen grains from anther to stigma. The two types of pollination found in flowering plants are: Self pollination: that occurs within the same plant. Cross-pollination: that occurs between two flowers of two different plants but of the same kind.

Please make me brainlist
Explanation:
Wind- Flowers pollinated by the wind are very small and dull; they have no nectar and they are not scented. The stigmas are long and exposed to help them catch the pollen grains blowing in the wind.
Water- In some aquatic pollen grains are released into water which then carried by the water to female flower
Self Pollination - When pollen grains from a flower are carried to the stigma of same or another flower on the same plant.
Cross pollination - When pollen grains from a flower are carried to the stigma of same or another flower on the another plant.
