How is gametophyte of Marchantia sp differ from the gametophyte of Polytrichum sp?
hehehe
What else can I help you with?
How is the gametophyte of marchantia sp different from the gametophyte of funaria sp?
The gametophyte of Marchantia sp is a thalloid liverwort that is flat and ribbon-like in structure, while the gametophyte of Funaria sp is a moss that consists of leafy structures. Marchantia sp also has specialized structures called gemma cups for asexual reproduction, whereas Funaria sp relies on spore dispersal for reproduction.
Why polytrichum sp are not widespread on land?
The polytrichum SP are not widespread on land because the conditions on land do not favor them to grow. In a nutshell, the Polytrichum SP cannot thrive on land.
Structural differences between marchantia and dryopteris?
Both Dryopteris sp. and Marchantia sp. live in damp areas.Their spores are produced by meiosis.
How is the gametophyte of marchantia sp differ from gametophyte of polytrichum sp?
Liverworts come in two basic types; the leathery, lobed thalloid sheets and the leafy or moss-like gametophytes. Only the edges of liverwort leaves have lobes or points. The leaves are aligned in two rows along the stem. Moss leaf edges may be serrated but are never lobed. The majority are smooth edged, all the same size, and are arranged in a spiral along the stem Only moss have phyllids (leaf-like flanges) with cells along the midline that have a facilitated internal osmosis of water: prevascular xylem-like hydroid cells and the phloem-like leptoid cells. Liverworts lack these cell types. -ahang-
What is the importance of gemmae cups to the marchnatia sp?
Gemmae cups in Marchantia sp. are crucial for asexual reproduction. These specialized structures contain gemmae, which are small, haploid fragments that can develop into new gametophyte plants. When water splashes onto the gemmae cups, the gemmae are dispersed, allowing for colonization of new areas. This reproductive strategy enhances the survival and spread of Marchantia in various environments.
What is the function of elater in the capsule Marchantia sp?
Elaters in the capsule of Marchantia sp. are responsible for aiding in seed dispersal. They help in the dispersal of spores by expanding and contracting in response to changes in humidity, effectively releasing spores into the environment.
Explain the importance of gemma cups to Marchantia sp?
Liverworts can also reproduce asexually by means of special structures called gemmae cups. These little cups can be easily seen on the surface of the plant. Each gemma cup contains a number of tiny plantlets called gemmae, and a single drop of water will disperse them. These little vegetative "clones" will then grow into a new gametophyte.
What is the comparison between spores and leaves of lycopodium sp. and selaginella sp.?
Lycopodium is Isophyllous,Homosporous.It has monocious gametophyte and do not have rhizophores.But Selaginella is Dimorphism, heterosporous.It has dioecious gmetophyte and rhizophores
What is an example of benthic diatoms?
Navicula sp.,Cymbella sp., Melosira sp.,Asteromphalus sp.
What is the next three numbers in the pattern 354555?
The number 5 is used as a spacer (sp) in the sequence. 3-sp-4-sp-5-sp-6-sp-7-sp.....
Why is SP snuff called SP?
just saying SP is shorter
How is a color a color?
A brand new Game-Boy Advance SP cost from £40 - £49.99, I guess the price range could differ on eBay or anyother Auction site.
