(b) State the need of exposed large feathery stigmas for the flower. (c) What will be the two important adaptations in the pollen grains of the flowers pollinated by the above mode of pollination ? (d) What could be the probable reason for the petals being small and non-green ?

Select the following statements that are true for insect pollinated flowers from the given options. (i) Majority of these flowers are large, colourful and rich in nectar. (ii) Nectars and seeds are usual floral rewards to attract insects for pollination. (iii) Pollen grains of these flowers are generally mucilaginous so as to stick to the body of the insects.

Select the statements that are true for pollination mechanism in flowering plants from the given options. (i) In Vallisneria, the female flowers are pollinated by pollen grains inside the water. (ii) In Zostera, pollen grains are released on the surface of water. (iii) In most of the water-pollinated species, pollen grains are covered by a mucilaginous coating. (iv) Pollination by water is quite rare and limited to about 30 genera. Choose the correct answer :
