Question
Which group is noted for the independence of gametophyte andsporophyte generations from each other?a) fernsb) mosses, hornworts, and liverwortsc) charophytesd) angiospermsPTO
Solution
The group that is noted for the independence of gametophyte and sporophyte generations from each other is b) mosses, hornworts, and liverworts.
Here's a step-by-step explanation:
-
In the life cycle of plants, there are two alternating generations: the gametophyte generation, which produces gametes (sex cells), and the sporophyte generation, which produces spores.
-
In most plants, one of these generations is dominant and the other is reduced and dependent on the dominant one. For example, in ferns and angiosperms, the sporophyte generation is dominant and the gametophyte is reduced and dependent on the sporophyte.
-
However, in mosses, hornworts, and liverworts, both the gametophyte and sporophyte generations are independent from each other. This means that both generations can live and grow separately from each other.
-
Therefore, the answer to the question is b) mosses, hornworts, and liverworts.
