Can anyone explain what is pressure gradient and concentration gradient?
what occupies space b/wcell wall & shrunken protoplast in plasmolysed cell?what wud be the pressure potential of flaccid cell? pls ans me!
why is osmotic pressure is positive and osmotic potential is negative??
What is diffusion pressure deficit? (DPD)
what is positive hydrostatic pressure gradient and a negative hydrostatic pressure gradient
explain the process of photosynthesis in detail.(please)
What would be the pressure potential of a flaccid cell? Which organisms other than plants possess cell wall?
what is the difference between porins and aquaporins? plz explain properly the difference in function too.
Why Lipids are not strictly macromolecules ??
What does this statement mean:
"Diffusion in solids rather than of solids is more likely."
WHAT ARE PORINS.WAHT IS IT FUNCTON
teacher, plz explain the difference betweeen plasmolysed cell and a flaccid cell.
plz explain in basic simple ways with examples. the definitions given in the book are hard to understand

water channels made up of eight different types of aquaporins.what is the meaning of this statement?
What is the difference between plasmolysis and osmosis?
answer in tabular form please
why does the water potential increases when applied pressure is greater than the atmospheric pressure in a pure water?
When any plant undergoes senescence, nutrients may be withdrawn from such regions and moved to the growing parts. Explain it.
give 3 difference between ascent of sap and translocation of food
it is given in ncert that"when water flows into the cell and out of the cell and are in equilibrium, the cells are said to be flaccid" plzz explain me that if the cells are in equilibrium then how can it be flaccid. it is a lil bit cnfusing plzzz help me experts
wht is ringing or girdling experiments?
transpiration and photosynthesis compromise each other. Comment.
why do dry seeds swell when they are placed in water??
give 2 reason why all mineral cannot be absorbed passively ?
what occupies the space between the cell wall and the shrunken protoplast in the plasmolysed cell?
1- does transpiration pull function in aquatic plants like lotus?give explanation for your ans
2- make a list of plants using C4pathway. what are other modifications which enables them to survive in harsh climates?
3- photosynthesis needs constant supply of water. but transpiration can hamper this supply. how do plants of deserts area manage to get sufficient water in spite of faster transport?
Gridling experiment cannot be permormed in sugar cane ecause
a-it cannot withstand injury
b-vascular bundles in it are scattered
c-phloem in it is situated internal to xylem
d-sugar cane plants are too delicate
which one is correcct?
How is positive hydrostatic pressure developed in phloem similar to that in a garden hose? And how is negative hydrostatic pressure equivalent to that produced while sucking a straw?
what is Hydrophilic moiety ?
