what occupies space b/wcell wall & shrunken protoplast in plasmolysed cell?what wud be the pressure potential of flaccid cell? pls ans me!
first year NCERT page no 183,
how many years it would take for the movement of molecules over a distance of 1m within a plant by diffusion alone?
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)
In case sucrose does diffuse out through the membrane, will this equilibirium be ever reached? (this question haq been taken from NCERT Book Page no 181 para 1.
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.
How many years it would take for the movement of molecules over a distance of 1m within a plant by diffusion alone?
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

what is adsorption?
What occupies the space between the cell wall and the shrunken protoplast in the plasmolysed cell?
what is the meaning of hydrophilic moiety...?
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 concentration gradient ?
Why cell is called an osmotic system?
What would be the pressure potential of a flaccid cell??which organisms other than plants possess cell wall??
how do plants reduce transpiration?
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?
what is the difference between turgor pressure and wall pressure?
What is the difference between plasmolysis and osmosis?
answer in tabular form please
what are guard cell ?Explain their role in regulating transpiration.
Can you tell of any system in our body where pressure is built up?
it is very urgent please post the answer as soon as you can
what is the difference between osmosis and diffusion.
explain wht xylem transport is unidirectional and pholem transport is bidirectional?
wht is ringing or girdling experiments?
The chief role of transpiration in plant to cause?
A- Loss of surplus water.
B- Colling of plant.
C- Rapid ascent of sap.
D-Rapid rise of mineral.
why is osmotic pressure is positive and osmotic potential is negative??
how does a turgor pressure gradient is formed between the supply site and consumption site?
transpiration and photosynthesis compromise each other. Comment.
last point of (relationship of transpiration and photosynthesis)is not cleared............please explain it in easy terms.
why do dry seeds swell when they are placed in water??
in imbibition, water is adsorbed by hydrophilic substances like pectin n cellulose in root hairs. so .. i mean its different from diffusion ryt? in diffusion water moves inside the cell.. so in imbibition , does the water accumulate in intrcellular spaces? if not plz correct me.
