Sexual Reproduction in Flowering Plants

Identify the set of correct statements:

A. The flowers of Vallisneria are colourful and produce nectar.

B. The flowers of water lily are not pollinated by water.

C. In most water-pollinated species, the pollen grains are protected from wetting.

D. Pollen grains of some hydrophytes are long and ribbon-like.

E. In some hydrophytes, the pollen grains are carried passively inside water.

Choose the correct answer from the options given below:

  1. A.A, B, C and D only
  2. B.A, C, D and E only
  3. C.B, C, D and E only✓
  4. D.C, D and E only

Solution

Vallisneria flowers are small and nectarless (A false); water lilies are pollinated by insects, not water (B true). Water-pollinated species protect pollen with a mucilaginous coat, some have ribbon-like pollen, and in some the pollen is carried passively under water. So B, C, D and E.
