Assertion: Both wind and water pollinated flowers are not very colourful and do not produce nectar. Reason: There is no need to attract the pollinating agents.

Identify the agent of pollination from the given floral characteristic features Flower are unisexual and pollen grains are produced in large quantities and are smooth, small and dry

+2 Students of a school at Kasaragod distric on their study tour collected flowers showing the following character: Flowers are with light pollen grains. Colourful flowers. Nector producing flowers. Flowers with feathery stigma. Write the name of 2 flowers pollinating through water.

Assertion: To compensate the uncertainties and associated loss of pollen grains during pollination by abiotic agents, the flowers produce enormous amount of pollen when compared to the number of ovules available for pollination. Reason: Pollen grains coming in contact with the stigma is a chance factor in both wind and water pollination.

Read the following statements carefully and select the appropriate option given below. (i) The distal end of the filament is attached to the thalamus or the petal of the flower. (ii) The pollen grains represent the male sporophyte. (iii) The microsporangia develop further and become embryo sac. (iv) In over 60 per cent of naked seeded plant, pollen grains are shed at this 2-celled stage. (v) As anthers mature and dehydrate the microspores, dissociate from each other and develop into pollen grains.

Transfer of pollen grains from anther to the stigma of flower is called pollination. Grass plants generally have small inconspicuous flowers while plants belonging to many angiosperm families bearing conspicuous coloured flowers. Comment on the type of pollinatin taking place in these two groups.
