Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Dominant generation is gametophyte generation. This statement is TRUE for ____
A
pteridophytes
B
bryophytes
C
angiosperms
D
gymnosperms
Explanation: 

Detailed explanation-1: -In bryophytes (mosses and liverworts ), the dominant generation is haploid, that is the gametophyte, which is the main plant itself. The sporophyte is dependent on gametophyte. Hence the correct option is C.

Detailed explanation-2: -In a bryophyte, all the vegetative organs belong to the gametophyte, which is the dominant and most familiar form; the sporophyte appears for only a short period.

Detailed explanation-3: -Bryophyta is a group of plants which do not bear fruits, seeds and vascular tissues. They are known as ‘amphibians of plant kingdom’. Their body is thalloid and green due to the presence of chloroplast. Male sexual organ is antheridium and female sexual organ is archegonium.

Detailed explanation-4: -In bryophytes, such as mosses and liverworts, the gametophyte is the dominant life phase, whereas in angiosperms and gymnosperms the sporophyte is dominant. The haploid phase is also dominant among fungi.

Detailed explanation-5: -The sporophyte is the dominant generation, but multicellular male and female gametophytes are produced within the flowers of the sporophyte.
