What is the life cycle of Marchantia?
In Marchantia sporophyte is represented by foot, seta and capsule. The sporophyte produces the spores in the capsule. The spores on germination produce the gametophyte. So, in Marchantia two morphologically distinct phases (Haplophase and Diplophase) constitute the life cycle.
Are Marchantia Monoecious?
The liverwort Marchantia is strictly dioecious. Noll showed in 1907 that the spores consist of two classes, those which grow into male plants and those which grow into female plants.
Is Marchantia Monoecious or dioecious?
dioecious
The liverwort Marchantia is strictly dioecious. Noll showed in 1907 that the spores consist of two classes, those which grow into male plants and those which grow into female plants.
What is the function of sporophyte?
Sporophyte is the diploid phase in the life cycle of a plant. It produces spores by meiosis that give rise to haploid gametophytes.
What is the role of the sporophyte?
The basic function of the sporophyte is to create spores – that much is known already. The spores, in turn, produce the gametophytes that give rise to the male and female gametes through the process of meiosis.
Which of the following is monoecious Marchantia?
(b) Pinus is monoecious as it bear male cone as well as female cone on same tree, (but on separate branches). Marchantia, Cycas and papaya are dioecious plants.
What is a Marchantia sporophyte?
Marchantia Sporophyte. These mature sporophytes are the asexual reproductive form for the Marchantia order of Bryophytes, moss-like plants of the division Bryophyta, also known as liverworts, or “liver plants.”. The thallus, part of the plants’ anatomy, has the appearance of a lobed liver, which gave rise to the name.
Where is Marchantia found?
Marchantia, a common liverwort, is generally found on moist soils, rocks, etc. There are about 65 species of Marchantia distributed throughout the world. Of the 4 species, M. palmata, M. nepalensis, M. simlana and M. polymorpha growing in India, the last-named one is very common and, practically speaking, it is cosmopolitan in distribution.
What is a sporophyte in biology?
These mature sporophytes are the asexual reproductive form for the Marchantia order of Bryophytes, moss-like plants of the division Bryophyta, also known as liverworts, or “liver plants.” The thallus, part of the plants’ anatomy, has the appearance of a lobed liver, which gave rise to the name.
How do Gametophytes reproduce in Marchantia?
Thalli, gametophytes and gemmae. The haploid thalli (single thallus) are dioecious: they produce either (female) archegoniophores or male antheridiophores. Moreover, in Marchantia asexual reproduction occurs by means of fragmentation of the thallus or via gemmae produced from cells of gemma cups.
