Question

Reproduction type in bryophytes

Answer 1

Vegetative reproduction in bryophytes is by fragmentation and budding.
SEXUAL REPRODUCTION
The main plant body of bryophyte is haploid . It produces gamete, hence is called a gametophyte. The reproductive organs in byophytes are multicellular. The male organ is called antheridium. They produce biflagellate antherozoids. The female organ called archegonium is flask shaped and produces a single egg. The antherozoids are released into water where they come in contact with archegonium. An antherozoid fuses with the egg to produce zygote. Zygote do not undergo reduction division immediately. They produce a multicellular body called a sporophyte. The sporophyte is not free living but attached to the photosynthetic gametophyte and derives nourishment from it. Some cells of the sporophyte undergo reduction division (meiosis) to produce haploid spores. These spores germinate to produce gametophyte.

Answer 2

$\huge{\boxed{\boxed{\underline{\bf Reproduction\:In\:Bryophytes}}}}$

Bryophytes reproduces through vegetative reproduction and sexual reproduction.

VEGETATIVE REPRODUCTION

It is a type of asexual reproduction through which bryophytes reproduce.

It includes : Fragmentation and Budding.

SEXUAL REPRODUCTION

The bryophytes are haploid in nature. The male organ is called the antheridium. Antheridium releases two antherozoids which are the male gamete. The female organ is the archegonium. Water is required for their fertilization. An antherozoid fuses with the archegonium in water and forms zygote. The zygote turns into a diploid sporophyte. The sporophyte on maturation produces haploid spores. The spores then germinates and gives rise to gametophytes.
