GCSE biology question, tissue culture..?

  • Thread starter Thread starter SJ :)

1) Select a parent plant with desired characteristics

2) Scrape off a lot of small pieces of tissue in the beaker containing nutrients and hormones. Make sure this process is done without the presence of bacteria (asepticallly) to avoid the new plants rotting.

3) Lots of genetically identical plantlets will then grow (these can be cloned aswell).

Finally, yes, tissue culture is more expensive than cuttings because in tissue culture you need to purchase a sterile agar jelly is needed during tissue culture
 
Taking cuttings? I don't think that has anything to do about culturing... Maybe I am wrong. Anyway, a tissue culture usually starts out with a sample, so you swab the site with a sterile swab. You place the sample (like, roll the swab in a petri dish) in a petri dish and add some solution which contains glucose, I think. Then the petri dish is sealed, and placed in a heater. It is not baked, but warmed to speed up any growth that there may be. If there is no growth over a space of one or two days, it is negative for growth. If there is a sign of growth, the growth should be looked at and identified so it can be treated.
I hope that helped!
