Describe the movement of water w.r.t.
1)water potential?
2)solute Potential?
3)pressure potential?
4)matric potential?
5)osmotic potential?
6)osmotic pressure
7)dpd(diffusion pressure deficit)
EXAMPLE: FROM HIGH WATER POTENTial TO LOW WATER POTENTIAL

Subject: Biology, asked on 8/4/18

If solute is added to pure water..describe(if decreases or increases)
1)water potential
2)solute Potential
3)pressure potential
4)matric potential
5)osmotic potential
6)osmotic pressure

Subject: Biology, asked on 12/3/18

Explain with reasons:
  • Solute can reach endodermis through apoplast but it moves through endodermis by symplast.
  • Insectivorous plants generally grow in waterlogged and swampy soils deficient in nitrogenous compounds.

Subject: Biology, asked on 11/2/18

What is glycolysis ? What is called EMP pathway ?Give the schematic representation of glycolysis .

Subject: Biology, asked on 31/1/18

The answer should be xerophytes because xerophytes will have least water inside them so the rate of osmosis will be the highest in them only and so will be the osmotic pressure.
