Question

Alternation of generation in the Bryophytes(moses,liverworts,hornworts)is caracterized by:

a)dominant gametophyte stage and small sporophyte stage that is dependent on the gametophyte stage

b)dispersal by spores,which are haploid and produced by the gameotophyte

c)dispersal by spores,which are deploid and produced by the sporophyte

d)multicellular gametangia produced within the sporophyte

Answer 1

Alternation of generation in the Bryophytes is characterized by- a) dominant gametophyte stage and a small sporophyte stage that is dependent on the gametophyte stage.

Alternation of generation is defined as the alternation of multicellular diploid and haploid forms in the life cycle of organisms. In bryophytes, the gametophyte generation is dominant and haploid where as, the sporophytic generation is dependent on the gametophytic generation and is diploid.
