what occupies space b/wcell wall & shrunken protoplast in plasmolysed cell?what wud be the pressure potential of flaccid cell? pls ans me!
What is diffusion pressure deficit? (DPD)
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 positive hydrostatic pressure gradient and a negative hydrostatic pressure gradient
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.
explain the process of photosynthesis in detail.(please)
what is the difference between turgor pressure and pressure potential
What would be the pressure potential of a flaccid cell? Which organisms other than plants possess cell wall?
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!! :)
what is the difference between porins and aquaporins? plz explain properly the difference in function too.
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
Differentiate between Turgid, flaccid and Plasmolysed cells?
What is hydrostatic pressure?What is the difference between positive and negative hydrostatic pressure?
Define water potential .
Explain pressure potential . How is it build up???
what is imbibition?
Can you tell of any system in our body where pressure is built up?
biology textbook ncert on page 180 fig answer is b to a ryt?
Mention 4 uses of transpiration.
what would be the pressure potential of a flaccid cell?
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?
why is osmotic pressure is positive and osmotic potential is negative??
Transpiration is a necessary evil. It is necessary..understood...but how it is an evil?
give 3 difference between ascent of sap and translocation of food
differentiate between osmosis and plasmolysis
What is the meaning of xylem lumen?
How many years it would take for the movement of molecules over a distance of 1m within a plant by diffusion alone?
Why Lipids are not strictly macromolecules ??
what is adsorption?
why do dry seeds swell when they are placed in water??
What occupies the space between the cell wall and the shrunken protoplast in the plasmolysed cell?
what is the meaning of hydrophilic moiety...?

answer in tabular form please
wht is ringing or girdling experiments?
FIRST YEAR NCERT page no 182,
1 what occupies the space between the cell wall and the shrunken protoplast in the plasmolysed cell?
2 what would be the psi pressure of a flacccid cell? which organisms other than plants possess cell wall?
transpiration and photosynthesis compromise each other. Comment.
Why is facilitated diffusion sensitive to inhibitors that react with protein side chains?
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?
whats cytoplasmic streaming?
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 does positive and negative pressure in xylem challens mean?plz explain clearly
what is Hydrophilic moiety ?
What is meant by apoplastic pathway?Why does it occur in cortex and not in endodermis?
Explain pressure flow hypothesis of
translocation of sugars in plants.
What is meant by cytoplasmic streaming in the sentence,'symplastic movement is aided by cytoplasmic streaming.'
what is difference between guttation and dew?
what is the difference between turgidity and rigidity?
The transpiration driven ascent of xylem sap depends mainly on 3 physical properties of water expain...?? ( explain in brief)
