Answer:
Advantages of self – pollination
In self- pollination, there is no diversity in the genes and therefore the purity of the race is maintained.
The plants do not depend on external factors for pollination and even smaller quantities of pollen grains produce have a good success rate in getting pollinated.
Self- pollination ensures that recessive characters are eliminated.
Disadvantages of self- pollination
Since there is no mixing up of genes, there are no new characters or features that are introduced into the lineage of the offsprings.
Self- pollination is said to reduce the vigor and vitality of the race as there are no new features introduced.
Without new characters introduced, the resultant offsprings’ immunity to diseases reduces.
Answer:
Water pollinated plants are aquatic. 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. Most aquatic plants are insect-pollinated, with flowers that emerge from the water into the air
