By convention, the water potential of pure water at standard temperatures, which is not under any pressure is taken to be zero. How ?
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.
Can you tell of any system in our body where pressure is built up?
What does this statement mean:
"Diffusion in solids rather than of solids is more likely."
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
WHAT ARE PORINS.WAHT IS IT FUNCTON
Can anyone explain what is pressure gradient and concentration gradient?
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

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?
