Which of the following moss structures is diploid?

Which of the following plant groups is incorrectly paired with its gametophyte generation? A. Lycophytes-either green or no photosynthetic tiny plants B. Moss-green manlike plant Fern-frond growing from horizontal stem D. Liverwort flattened, low-growing green plant

Explanation / Answer

27.The correct answer is:A.capsule

Reason: Capsule is a part of sporophyte and therefore diploid.Foot,stem and leaves are haploid and represent dominant gametophyte generation.

28.The correct answer is:D.3,1,2

Reason:Gametophytes are largest followed by antheridia that are the male sex organs that contain gametes inside them.So gamates are the smallest,

29.The correct answer is:C.Fern-frond growing from horizontal stem.

Reason:The above option is incorrectly paired from all other options.
