The bryophytes liverworts are so named as they are an example of:
1. a plant that causes warts
2. a plant that cures liver diseases
3. the Doctrine of Signatures

Seed plants are source of some very important medicines for humans. Identify the pair where the drug in Column I is not correctly matched with its source seed plant in Column II:

Consider the given two statements:
I. The term ‘archegonium’ is not used for megagametophytes, angiosperms and gnetophytes.
II. The sperms are delivered by means of a pollen tube in these plants.

1. Both I and II are correct and II explains I
2. Both I and II are correct but II does not explain I
3. I is true but II is false
4. Both I and II are false

Consider the given two statements:
I. Formation of a multicellular haploid gametophyte as in ferns rather than limiting it to a few cells is believed to provide an evolutionary advantage.
II. The transmission of harmful traits is less likely to occur to the future generations.

1. Both I and II are correct and II explains I
2. Both I and II are correct but II does not explain I
3. I is true but II is false
4. Both I and II are false

Rather than having true roots, stems and leaves the members of Phaeophyceae have root like holdfast, stem like stipe and leaf like fronds. What will be true for these structures?

I. Holdfasts are not the primary organs for water and nutrient uptake.
II. In brown algae like Fucus, the tissues in stipe include a central pith, a surrounding cortex and an outer epidermis.
III. Gas filled floats called pnematocysts provide buoyancy in many brown algae.

1. I and II only
2. I and III only
3. II and III only
4. I, II and III

What would be true for the structure labeled with letter ‘X’ in the given diagram showing the ultrastructure of Chlamydomanas?

1. It is the region of the chloroplast where circular DNA is present
2. It is associated with the operation of a carbon-concentrating mechanism (CCM)
3. It is the inclusion body with accumulated toxic wastes for elimination
4. It is filled with air and is responsible for buoyancy of the organism

The diagram shows a sorus in section in ferns. What would be the name for A?

1. Annulus
2. Placenta
3. Indusium
4. Stomium

In the given longitudinal section of archegonium of moss identify A, B, C and D respectively:
 

1. Ventral canal cell, Neck canal cell, Egg, Venter
2. Ventral canal cell, Neck canal cell, Venter, Egg
3. Neck canal cell, Ventral canal cell, Venter, Egg
4. Neck canal cell, Ventral canal cell, Egg, Venter

Consider the given two statements:

I. The term ‘embryophytes’ is an appropriate synonym for plants.
II. The occurrence of a multicellular, matrotrophic embryo in plants from bryophytes through angiosperms.

1. Both I and II are correct and II explains I
2. Both I and II are incorrect but II does not explain I
3. I is correct but II is incorrect
4. Both I and II are incorrect

Consider the two trends in evolution of plants:

I. A reduction of vascular tissues occurs from gymnosperms and woody dicots to herbaceous dicots to monocots
II. The gametophytes of vascular plants have become smaller and simpler

1. Both I and II are correct
2. Only I is correct
3. Only II is correct
4. Both I and II are incorrect
