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)
what is the difference between turgor pressure and pressure potential
what is positive hydrostatic pressure gradient and a negative hydrostatic pressure gradient
Why is facilitated diffusion sensitive to inhibitors that react with protein side chains?
explain the process of photosynthesis in detail.(please)
why is osmotic pressure is positive and osmotic potential is negative??
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.
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???
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!! :)
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 imbibition?
difference between transport protein and carrier protein ?
biology textbook ncert on page 180 fig answer is b to a ryt?
what would be the pressure potential of a flaccid cell?
What is the meaning of xylem lumen?
Transpiration is a necessary evil. It is necessary..understood...but how it is an evil?
differentiate between osmosis and plasmolysis
Why Lipids are not strictly macromolecules ??
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 adsorption?
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 the meaning of hydrophilic moiety...?
Can you tell of any system in our body where pressure is built up?
what is concentration gradient ?
What would be the pressure potential of a flaccid cell??which organisms other than plants possess cell wall??
How many years it would take for the movement of molecules over a distance of 1m within a plant by diffusion alone?
how do plants reduce transpiration?
what is the difference between turgor pressure and wall pressure?
What is the difference between plasmolysis and osmosis?
answer in tabular form please
Mention 4 uses of transpiration.
give 3 difference between ascent of sap and translocation of food
DO DIFFERENT species of plants growing in the same soil show the same rate of transpiration atsame time .justifyyour answer
wht is ringing or girdling experiments?
transpiration and photosynthesis compromise each other. Comment.
the diffusion of any substance across a membrane also depends on its solubility in lipids the major constituent of the membrane. comment
why do dry seeds swell when they are placed in water??
give 2 reason why all mineral cannot be absorbed passively ?
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 occupies the space between the cell wall and the shrunken protoplast in the plasmolysed cell?
Name two anti-transpirants
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 ?
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 difference between guttation and dew?
water channels made up of eight different types of aquaporins.what is the meaning of this statement?
what is the difference between turgidity and rigidity?
FORCE DEVELOPED IN CORTEX OFROOT WHICH PUSHES WATER IN TO XYLEM OF ROOT FROM SOIL IS 1] DIFFUSION 2] OSMOTIC PRESSURE 3] TURGOR PRESSURE 4 ] ROOT PRESSURE
the passive absorption of water from soil is mainly affected by,
a)tissue organization of root
b)sucking power of root hairs
c) tension of cell sap due to transpiration
d)osmotic concentration of cell sap
