Describe two ways by which NH4+ is used to synthesize amino acids in plants.
what is the meaning of ureides?
What is mean by interveinal chlorosis, mottled chlorosis and necrosis?
what would happen if the solutions used in hydroponics were poorly aerated???
can anyone send nitrogen cycle in any other type??
what is leg haemoglobin?
curling of root hair tips during nitrogen fixation is caused due to nod factor.
bt is this nod factor produced by bacteria and thenninduced into the root or is it produced by the plant?
also give some info bout nif and fix gene.. n who produces it.
and there s another question ...the corrct ans given is C ..i agree bt cant it be B too?
plz explain ur ans Q- during root nodule formation in legumes
a) nod factors are produced by legumes only
b) nod, nif, fix genes of legumes are activated
c) cytokinin lvl increases in roots.
why is leg haemoglobin is called oxygen scavenger?
Explain with examples:
