why purified water and mineral nutrient salts essential for hydroponics?
wht r nodules? explain it's formation n give a diagram 4 it.....
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?
why is leg haemoglobin is called oxygen scavenger?
hydroponics with diagram
Explain with examples:
macronutrients, micronutrients, beneficial nutrients, toxic elements
and essential elements.
1.What are the different criteria for essentiality of an element?
hello, in the video Rhizobium is given as Rhizobum.... pls do change it sir/mam....
Sulphur is an important nutrient for optimum growth & productivity in Oilseed crops or Pulse crops.
What is the correct answer oilseed crops or pulse crops & why?
what is chlorosis, necrosis, inhibition of cell division , delayed flowering?
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?
a farmer adds azotobacter culture to soil before sowing maize .which mineral element is being replenished
what role does nitrogen play in plant metabolism ? 1 mark
Examples of chlorosis and necrosis ?
Explain symbiotic biological nitrogen fixation.
explain the process of nitrogen fixation in leguminous plants?
Pls give an example or ammonifying bacteria.
what does "against the concentration gradient " mean???????
explain very briefly the process of biological nitrogen fixation in the nodule
What is whiptail disease in cauliflower? What are its external symptoms?
mention the role of any four micronutrient in plants
what would happen if adequately aerated nutrient solutions are not emphasised?
What is guttation ?
What is auxin?
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
Why is Zinc needed in the synthesis of auxin?
NAME THE ELEMENT THAT ACTIVATES
A] ALCOHOL DEHYDROGENASE
define apical dominance????
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?
explain why hydroponics are so essential in plants?
Describe two ways by which NH4+ is used to synthesize amino acids in plants.
Name 2 organisms each which fix nitrogen asymbiotically and symbiotically.
Wat is Hydroponics ......... ???? ......... ????
how does leghaemoglobin protect the nitrogenase ?
how can the essential elements alter the osmotic potential of a cell??
Which macronutrient is essential for synthesis of auxin.
Dear Sir / Madam,
what is organic nitrogen? Can you please include a video for nitrogen fixation and make the concept a little more clear?
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.
Plants absorb substances such as nitrate ions by active uptake from the soil. What do you mean by active uptake?
what is your opinion regarding the human activities that have disrupted the movement of minerals in the ecosystem?
