the gametophyte of marchantia sp is thalloid and dorsi-ventrally flattened while that of funaria sp is differentiated into leaf-like, stem-like and root-like structures
arthrobacter sp., psychrobacter sp.,
SP means a ring is silver plated
Sp is not a symbol for a chemical element.
There are three types of sp hybrid orbitals: sp...180 degrees sp2...120 degrees sp3...109 degrees
sp or sp1 bonds are triple bonds. For carbon to carbon bonds, the easiest way to work it out is take the number after the "sp" and subtract it from 4 ( the normal number of bonds to carbon). Therefore "sp1 or sp" 4-1=3, so triple bond
hehehe
Both Dryopteris sp. and Marchantia sp. live in damp areas.Their spores are produced by meiosis.
i dont know..you should blame on matriculation programme
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.
Lycopodium is Isophyllous,Homosporous.It has monocious gametophyte and do not have rhizophores.But Selaginella is Dimorphism, heterosporous.It has dioecious gmetophyte and rhizophores
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-
allium sp does not contain chloroplast while hydrilla sp cell does contain chloroplast because the colour of the hydrilla itself is green.
Lycopodium has only one size of spores said to homosporous while Selaginella has both a microspore that grows into the male gametophyte and macrospores that produces female gametophytes. Selaginella has ligules at the base of each microphyl
yes cos sp's and gba's are the same, but just have different cases
Yes, they are actually the same thing, only SP is looking different.
Platys are Xiphophorus sp. Mollys are Poecilia sp. As you can see they are of entirely different species and so obviously they can not breed with one another.
The letters "sp" (either in lower or upper case) can have several different meanings. Sometimes it is used by an editor to note a spelling error. In upper case (SP) it can stand for Shore Police (to the navy), or (to a Scientologist) Suppressive Person.
