Name at least five
different deficiency symptoms in plants. Describe them and correlate
them with the concerned mineral deficiency.

What is whiptail disease in cauliflower? What are its external symptoms?
mention the role of any four micronutrient in plants
what is diffusion pressure, osmotic pressure,turgor pressure,diffusion pressure deficit or suction pressure?........how are they related to each other.....i mean which of them are directly proportional or inversely proportional to each other?
explain very briefly the process of biological nitrogen fixation in the nodule
What is auxin?
Which ofthe following statements are true? If false, correct them:
(a) Borondeficiency leads to stout axis.
(b) Everymineral element that is present in a cell is needed by the cell.
(c)Nitrogen as a nutrient element, is highly immobile in the plants.
(d) It isvery easy to establish the essentiality of micronutrients becausethey
are required only in trace quantities.
Suggest some human diseases which we can take for investigatory projects?
Name the mineral element required for phtolysis of water in photosynthesis. How is it absorbed by plants?
Describe nod gene, nif gene, fix gene?
what is the another name for nitrogen cycle
how can the essential elements alter the osmotic potential of a cell??
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.
what is ammonification?
wht r nodules? explain it's formation n give a diagram 4 it.....
explain why hydroponics are so essential in plants?

NAME THE ELEMENT THAT ACTIVATES
A] ALCOHOL DEHYDROGENASE
how does leghaemoglobin protect the nitrogenase ?
plz provide a video on nitrogen cycle as soon as possible
i hope this time i will be replied soon bcoz i am waiting for a long time for many of my questions' answers........plz be fast in providing a video or at least more explained nitrogen cycle with an easy diagram too.
