Question

Read the following statements and find out the incorrect statements.

a. Plants use two abiotic (wind and water) and one biotic (animals) agent to achieve pollination.

b. Majority of plants use abiotic agents for pollination.

c. Only a small proportion of plants uses biotic agents.
d. Pollination by water is common among abiotic pollinators.

e. Pollination by wind is quite rare in flowering plants and is restricted to about 30 genera mostly monocotyledons.

• A.
  $a,b,c$ and $d$
• B.
  $b,c,d$ and $e$
• C.
  $b$ and $d$ only
• D.
  $a,c,d$ and $e$

Answer 1

The correct option is B

$b,c,d$ and $e$
Statement a
Cross-pollination is the process of transfer of pollen from the anther to the stigma of another flower either on the same or on different plants. It is achieved by the following agents:
1.Biotic agent: Animals
2.Abiotic agents: Water, wind
Thus, statement a is correct.

Statement b
Biotic agents (bees, insects, bats and birds) of pollination are responsible for pollination in a majority of the plants. Thus, statement b is incorrect.

Statement c
Abiotic agents of pollination are responsible for pollination in some plants only. Thus, statement c is incorrect.

Statement d
Wind pollination is more common amongst pollination by abiotic factors and is mainly observed in grasses. Thus, statement d is incorrect.

Statement e
Pollination by water is quite rare in angiosperms and is observed in only 30% of the plant genera, most of which are monocots. Thus, statement e is incorrect.
