In the life cycle of a moss, the sporphytic generation is represented by all the following except:

Identify the incorrectly matched row:

The structure in phanerogams that is homologous to the megasporangium of cryptogams is known as:
1. Embryo sac
2. Pollen sac
3. Nucellus of the ovule
4. Carpel

Sphagnum can be distinguished from mosses by all the following characteristics except:
1. The stem has no rhizoids
2. Leaves have green and hyaline cells
3. The sex organs do not limit the indefinite growth of the main axis
4. The capsule is borne on seta

Aplanogametes [gametes that do not have flagella] are the special features of:
1. Spirogyra and Zygnema
2. Spirogyra and Vaucheria
3. Ulothrix and Zygnema
4. Chlamydomanas and Ulothrix

Match each item in column I with one in Column II and select the correct answer from the codes given below:

Codes:

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

In contrast to conifers, gnetophytes produce:
1. Simple pollen strobili and simple seed strobili
