Asseration : In lichens, mycobiont and phycobiont are symbiotically associated in which algae is predominant and fungi is a subordinate partner. Reason : The fungus provides food and alga protects the fungus from unfavourable conditions.

A : Phycobiont is dominant parent in lichens. R : Algal component in the dual organisms can be eukaryotic only.

Mark True (T) or False(F) for the following statements & choose the correct option. (A) Phycobiont partner of lichens synthesises food for its other partner, (B) Lichens do not grow in air polluted areas, (C) Animals store their food reserve in the form of glycogen or fat

Which of these statement/s about lichens is/are ture? I. Lichens are mutually beneficial symbotic associations. II. They grow extensively in area with high pollution, hence called as pollution indicators. III. The phycobiont member, algae, is an autotroph and the mycobiont member, fungi, is a heterotroph. IV. Fungi help the algae harvest sunlight for photosynthesis.

A : Azotodesmic lichens are biofertilisers enriching nitrogen contents in soil. R : This ability is due to the presence of heterocystous blue-green algae as phycobiont component.
