Question

What is the alternation of generation in bryophytes?

Answer 1

Bryophytes:

1. They grow in the amphibious zone, which is the transition between aquatic and terrestrial ecosystems, and are so known as amphibians of plant.
2. Their body is made up of leafy multicellular green plants.
3. True roots, stems, and leaves are absent from the plant body.
4. The plants are chloroplast-rich and green.
5. They show that they eat in an autotrophic manner.

Alteration of Generation:

1. Generational alternation involve two stages of life that alternate on a regular basis.
2. The first stage is the gametophytic phase, during which gametes with half chromosomes are produced.
3. Bryophytes reproduce sexually via egg and sperm at this phase of their lives.
4. The second phase begins when egg and the sperm unite to form a zygote.
5. The zygote germinates to give rise to sporophyte, which contain all of the chromosomes.
6. The spore-producing phase is the second stage, sporophytic phase.
7. The sporophyte can't exist on its own. It is made up of capsule, foot and stalk that connects the sporophyte and gametophyte bodies.
