Anemophilous type of pollination is found in
1 Salvia
2 Bottle brush
3 Vallisneria
4 Coconut
Explanation:
Anemophilous type of pollination is found in coconut. Wind pollination is also known as anemophilous pollination. In this type of pollination, pollen grains are dispered by wind or air. Pollen grains are generally produced in large numbers and they are light weighted. So that they can be carried by the wind or air to a very long distance. In Salvia, pollination takes place by the insects, whereas in vallisneria, it occurs with the help of water and in Bottle brush, it occurs with the help of birds.

The type of pollination found in Calotropis is :
1 Dicliny
2 Herkogamy
3 Heterostyly
4 Dichogamy
Explanation:
The type of pollination found in calotropis is herkogamy. Herkogamy is a type of cross-pollination in which pollen transfer from anther of a flower to the stigma of a different flower, with the help of pollinating agent. Calotropis is an insect pollinating plant.
Anthesis is opening of flower which is followed by meiosis during which both male and female gametes are formed. Then pollination takes place. It can be either self pollination or cross-pollination. Pollination leads to the fusion of gametes called syngamy and produce embryo.

In nature, autogamy in plants is avoided since the seeds produced :
1 are fewer in number
2 do not germinate successfully
3 do not produce healthy plant
4 all of the above
Explanation:
Autogamy is a type of self-pollination which involves self-fertilisation. It involves fusion of gametes that are coming from same flower. i.e. pollens from the anther of a flower transferred to the stigma of the same flower. However, in nature autogamy in plants is avoided because the seeds produced are fewer in number, do not germinate successfully and do not produce healthy plant. Autogamy often results in inbreeding depression. It also decreases the disease resistant capability of a plant.
