the following statements are true? If false, correct them:
deficiency leads to stout axis.
mineral element that is present in a cell is needed by the cell.
Nitrogen as a nutrient element, is highly immobile in the plants.

NAME THE ELEMENT THAT ACTIVATES
A] ALCOHOL DEHYDROGENASE
what is the another name for nitrogen cycle
what are macro nutrients and micronutrients?
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.
elements that are present in a plant need not be essential to its
