BRYOPHYTES

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Bryophytes display alteration of generations.
A
TRUE
B
FALSE
Explanation: 

Detailed explanation-1: -The bryophytes show an alternation of generations between the independent gametophyte generation, which produces the sex organs and sperm and eggs, and the dependent sporophyte generation, which produces the spores.

Detailed explanation-2: -Some of the cells (spore mother cells) undergo meiosis and produce haploid cells which further germinate to produce gametophyte. All bryophytes are homosporous. They show heteromorphic alternation of generations because gametophytic and sporophytic bodies are conspicuously different.

Detailed explanation-3: -So, the correct answer is ‘Diploid generation is followed by haploid generation’.

Detailed explanation-4: -Generational alternation involve two stages of life that alternate on a regular basis. The first stage is the gametophytic phase, during which gametes with half chromosomes are produced. Bryophytes reproduce sexually via egg and sperm at this phase of their lives.

Detailed explanation-5: -Bryophyta is a division of non-vascular terrestrial plants. They consist of mosses, liverworts and hornworts. They are commonly found in moist and shady places. Bryophytes need water to complete their life cycle, so they are also called amphibians of plants.
