what does "True to type" in Micropropagation mean?
456870
all off spring plants will be similar to that of parent plant in all characters .even the delicate characters like taste ,colour shape of fruit ,smell are 100%similar.\n\nthis true to type nature is obtained by going for vegetative or asexual propagation methods like budding, grafting, stem cuttings, root cuttings, leaf cuttings etc.

Well, as far as plants are concerned... Many characteristics are very vague in the keys (such as tall vs. short).  Some of the characteristics can only be used during certian stages of the life cycle and sometimes you must go with the perponderence of evidence.  For an example of this, try keying out willows.

Transgenic plants are plants that possess a gene or genes that have been transfered from a different species. Such modification may be performed through ordinary hybridization through cross-pollination of plants, but the term today refers to plants produced in a laboratory using recombinant DNA technology in order to create plants with specific characteristics by artificial insertion of genes from other species, and sometimes entirely different kingdoms. See also Genetics, List of genetic engineering topics.\n\nPrior to the current era of molecular genetics starting around 1975, transgenic plants including cereal crops were (since the mid 1930s) part of conventional plant breeding.\n\nTransgenic varieties are frequently created by classical breeders who deliberately force hybridization between distinct plant species when carrying out interspecific or intergeneric wide crosses with the intention of developing disease resistant crop varieties. Classical plant breeder may use use of a number of in vitro techniques such as protoplast fusion, embryo rescue or mutagenisis to generate diversity and produce plants that would not exist in nature.\n\nSuch traditional techniques (used since about 1930 on) have never been controversial, or been given wide publicity except among professional biologists, and have allowed crop breeders to develop varieties of basic food crop, wheat in particular, which resist devastating plant diseases such as rusts. Hope is one such transgenic wheat variety bred by E. S. McFadden with a transgene from a wild grass. Hope saved American wheat growers from devastating stem rust outbreaks in the 1930s.

Plant tissue cultures isolated from even a single cell can show variation after repeated subculture. Distinct lines can be selected with their own particular morphology and physiology. It suggests that the tissue culture contains a population of genotypes whose proportion can be altered by imposing an appropriate selection pressure. This variation can be transmitted to plants regenerated from the tissue cultures, and is called somaclonal variation. It provides an additional source of novel variation for exploitation by plant breeders.

There is no such thing as "vitro" fertilisation, the expression is "in vitro".  The expression (latin) means literally "in glass" and so is sometimes referred to as "in petri dish" or "testtube".  The other method is "in vivo" (latin) meaning literally "in life".  This is where the the husband produces an insufficient number of sperm in any one ejaculation to guarantee impregnation, so a number of ejaculations are stored up until a sufficient sperm count is achieved and then the "whole batch" is implanted into the wife.  In "in vitro" fertilisation, the sperm and egg are introduced to each other in a petri dish and once impregnation has occurred, the fertilised egg is then implanted in the wife.

I'm not sure exactly what you are asking, but I'm assuming you want to know how microbiology is similar to stem cell cultivation.\n\nMicrobiologists use media (agar) that has different types of nutrients embedded into it that promote the growth of the organism they want to isolate.  These plates are placed into incubators that also promote the growth of the organism they are trying to isolate.  Sterile technique is used throughout the process to ensure that the media and specimen is not contaminated.  Colonies with desired characteristics are selected and replated on media several times until only the desired organism is isolated.  It is then tested to determine its species and subspecies before resulting the test and making recommendations.\n\nTissue cultures are cells that have also been plated on media that promote the growth of the desired tissue.  In this case, heart valves.  The innoculated media is then placed into incubators.  Desired tissue is tested and placed on new media in order to create a pure tissue source.  Once the desired tissue is grown, it is tested for the presence of the desired antigens, etc.

it is the potassium pump mechanism which pumps k+ ions actively ind other ions like cl-, malate ions enter passively and thereby increasing the solute potential of the guard cell and increasing the turgidity\n\nbut the cellulose micro fibrils do not allow radial expansion of the cell\n\ntherefor the guard cell's outer wall expand but due to thickening of inner wall it can't expand!!\n\nthere for along with the outer thin wall, the inner wall is also being pulled out!!!\n\ntherefor increasing the width of the stomatal pore and causing stomatal opening!!!!!!!!!!!!\n\nalso he wise versa

That quote sounds like an AFL-CIO or UAW speech opposing robotization in the plants but I am unfamiliar with the source. You might query People's Tribune (Online Edition) -  Email: pt@noc.org. They might be able to pin it down for you. I hopoe this is helpful to you.

With modern C++ compilers you do have the bool (note minuscules) type. You can declare it like this:\n\nbool myBooleanVariable;\n\nYou may assign literals to it (literals for the bool data type are 'true' and 'false'):\n\nmyBooleanVariable = true;\nmyBooleanVariable = false;\n\nYou may assign them the result of boolean operations:\n\nmyBooleanVariable = (a > 5) && (b < 2);\n\nYou may declare functions to return bool results:\n\nbool IsInvoiceCurrent();\n\nYou may also test for their values directly:\n\nif (myBooleanVariable) ...\nif (!myBooleanVariable) ...

They're talking about the plant cell model...not the actual plant cells.

your teacher needs to work bettering his/her questions. Or you need to re-phrase the questions so their is more detail.\n\nI was given a similar question on a take home exam, but I think it contained some more information, so I actually learned something.\n\nWith the information given, the one thing you can find out about this plasmid is what gene it posseses that allows its antibiotic resistance.  \n\nYou would do this by plating out the plasmid on agar plates that contain different antibiotics i.e. kanamycin, ampicillin.\n\nYou can pick the colonies that grow, and test for the "glo" gene.  This would verify the presence of the antimicrobial gene from which the colony was picked from.\n\nIn other words, the colony which has the "glo" gene also contains the gene resistant to the antimicrobial agent it was on  grown on.\n\n\nI hope this helps.  Pass on the good Karma!

Phenotypes: AB+ or AB-\n\nAntigens: A and B\n\nGenotypes: AB (+ or -)\n\nThanks micro_girl.  I should have made that more clear.  A and B are separate proteins, and when they are both present the resulting phenotype is AB.  Sorry if my original answer was misleading.  I fixed it.
