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 the difference between turgor pressure and pressure potential
what is positive hydrostatic pressure gradient and a negative hydrostatic pressure gradient
explain the process of photosynthesis in detail.(please)
What does this statement mean:
"Diffusion in solids rather than of solids is more likely."
What would be the pressure potential of a flaccid cell? Which organisms other than plants possess cell wall?
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 the difference between porins and aquaporins? plz explain properly the difference in function too.
describe the cohesive force theory of ascent of sap in plants.
WHAT ARE PORINS.WAHT IS IT FUNCTON
What forces are involved in absorption of water from soil by root hairs?
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 imbibition?
Can you tell of any system in our body where pressure is built up?
what would be the pressure potential of a flaccid cell?
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.
biology textbook ncert on page 180 fig answer is b to a ryt?
not dependent on the living system... means
Transpiration is a necessary evil. It is necessary..understood...but how it is an evil?
What is meant by apoplastic pathway?Why does it occur in cortex and not in endodermis?
differentiate between osmosis and plasmolysis
water channels made up of eight different types of aquaporins.what is the meaning of this statement?
Name two anti-transpirants
Why Lipids are not strictly macromolecules ??
What occupies the space between the cell wall and the shrunken protoplast in the plasmolysed cell?
how do plants absorb water?explain the transpiration pull model?
what is adsorption?
what is the meaning of hydrophilic moiety...?
Why is facilitated diffusion sensitive to inhibitors that react with protein side chains?
what is concentration gradient ?

What would be the pressure potential of a flaccid cell??which organisms other than plants possess cell wall??
what is the difference between turgor pressure and wall pressure?
Mention 4 uses of transpiration.
What is the difference between plasmolysis and osmosis?
answer in tabular form please
how do plants reduce transpiration?
How many years it would take for the movement of molecules over a distance of 1m within a plant by diffusion alone?
wht is ringing or girdling experiments?
why is osmotic pressure is positive and osmotic potential is negative??
give 3 difference between ascent of sap and translocation of food
what occupies the space between the cell wall and the shrunken protoplast in the plasmolysed cell?
why do dry seeds swell when they are placed in water??
In young roots water enters directly into the xylem vessels and/or tracheids. These are NON-LIVING conduits and so are parts of apoplast." Does this mean that apoplast pathway occurs in dead/non-living parts of the plant??
thank you!! :)
give 2 reason why all mineral cannot be absorbed passively ?
What determines the direction of flow of water from one cell to another cell?
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 Hydrophilic moiety ?
Explain pressure flow hypothesis of
translocation of sugars in plants.

i) Name this process.
ii) Give reasons for this occurance.
