In which of the following plants, the gametophytic generation is larger, dominant and autotrophic?
a) algae
b) mosses
c) liverworts
d) all of these
Explanation: In plants, the gametophyte generation is one that which begins with a spore that is haploid (n). The spore undergoes series of mitotic divisions to give rise to a gametophyte. A gametophyte is a haploid multicellular plant form
In which of the following plants, the sporophytic generation is smaller, less complex and heterotrophic?
a) algae
b) mosses
c) liverworts
d) all of these
Explanation: partially or totally dependent upon the gametophyte
In which of the following alga/e, both the gametophytic and sporophytic generations are independent and morphologically identical?
a) Ulva
b) Ectocarpus
c) volvox
d) both a and b
The gametophyte of ulva is ……….
a) diploid
b) triploid
c) haploid
d) polyploidy
Independent gametophyte and sporophyte is found in……..
a) liverworts
b) Ectocarpus
c) tracheophytes
d) mosses
Alternation of generations in plants is regarded a mechanism for……
a) achieving haploidy
b) promoting survival
c) producing triploidy
d) producing diploidy
