PLANT GENETICS QUIZ

both (a) and (b)

organic acid such as citric, fumaric, malic and succinic acid is used

synthetic buffers such as Tris, MES or HEPS are used

ammonium salts are used

it is removed aseptically from the culture and is autoclaved before use

It is liquid removed from the suspension of fast growing cells

It contains uncharacterized growth factor released by growing cells

It is used in the culture of regenerating protoplast

to adjust the osmotic potential of the media in short term treatment for regeneration

none of these

in specialized secondary metabolite production

Both (a) and (b)

Succinic acid

Silver thiosulphate

utilization of both ammonium and nitrate result in drop in pH

utilization of both ammonium and nitrate result in rise in pH

utilization of nitrate cause culture pH to drop while utilization of ammonium cause culture pH to rise

utilization of ammonium cause culture pH to drop while utilization of nitrate cause culture pH to rise
