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)
Mention 4 uses of transpiration.
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.
WHAT ARE PORINS.WAHT IS IT FUNCTON
give 3 difference between ascent of sap and translocation of food
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
Why Lipids are not strictly macromolecules ??
What does this statement mean:
"Diffusion in solids rather than of solids is more likely."
What forces are involved in absorption of water from soil by root hairs?
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???
why is osmotic pressure is positive and osmotic potential is negative??
what is imbibition?
what would be the pressure potential of a flaccid cell?
biology textbook ncert on page 180 fig answer is b to a ryt?
Transpiration is a necessary evil. It is necessary..understood...but how it is an evil?
differentiate between osmosis and plasmolysis
if a cell A with DPD 4 bars is connected to cells,B,C,D whose OP and TP are respectively 4 and 4,10 and 5 and 7 and 3 bars ,the flow of water will be ,? PLZ EXPLAIN
What is the meaning of xylem lumen?
What occupies the space between the cell wall and the shrunken protoplast in the plasmolysed cell?
How many years it would take for the movement of molecules over a distance of 1m within a plant by diffusion alone?
what is adsorption?
what is the meaning of hydrophilic moiety...?
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 is concentration gradient ?
what causes leaves of the grasses to roll in dry weather ?is it coz of low water concentration in soil leading to loss of transport of water n hence coz of that the leaves rool to reduce transpiration ( just a guess ) ??
What would be the pressure potential of a flaccid cell??which organisms other than plants possess cell wall??
pinus seeds cannot germinate and establish without the prescence of mycorrhiza based on the given statement,explain mycorrhiza
what is the difference between turgor pressure and pressure potential
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?
Why is facilitated diffusion sensitive to inhibitors that react with protein side chains?
What is the difference between plasmolysis and osmosis?
answer in tabular form please
how do plants reduce transpiration?
wht is ringing or girdling experiments?
what is difference between guttation and dew?
Can you tell of any system in our body where pressure is built up?
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??
transpiration and photosynthesis compromise each other. Comment.
give 2 reason why all mineral cannot be absorbed passively ?
What is meant by apoplastic pathway?Why does it occur in cortex and not in endodermis?
what is Hydrophilic moiety ?
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!! :)
Explain pressure flow hypothesis of
translocation of sugars in plants.
what is the difference between turgidity and rigidity?
what is meant by translocation can u give an example?
what is casparian strips
Define Osmotic potential and Osmotic pressure
Could you please explain the difference between hypertonic and hypotonic solution .It is very urgent.
what is the mechainism in the process of transpiration?
