what is positive hydrostatic pressure gradient and a negative hydrostatic pressure gradient
explain the process of photosynthesis in detail.(please)
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
Can anyone explain what is pressure gradient and concentration gradient?
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 is osmotic pressure is positive and osmotic potential is negative??
Differentiate between Turgid, flaccid and Plasmolysed cells?
not dependent on the living system... means

what is imbibition?
what is the difference between turgor pressure and pressure potential
biology textbook ncert on page 180 fig answer is b to a ryt?
what would be the pressure potential of a flaccid cell?
Transpiration is a necessary evil. It is necessary..understood...but how it is an evil?
By convention, the water potential of pure water at standard temperatures, which is not under any pressure is taken to be zero. How ?
What is the meaning of xylem lumen?

differentiate between osmosis and plasmolysis
State one artificial condition which may stop non-cyclic photophosphorylation and trigger cyclic photophosphorylation ?
what is chemical stimuli
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...?
it is given in ncert that"when water flows into the cell and out of the cell and are in equilibrium, the cells are said to be flaccid" plzz explain me that if the cells are in equilibrium then how can it be flaccid. it is a lil bit cnfusing plzzz help me experts
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?
why does the water potential increases when applied pressure is greater than the atmospheric pressure in a pure water?
what is the difference between turgor pressure and wall pressure?
What is the difference between plasmolysis and osmosis?
answer in tabular form please
whats the difference between turgor pressure and pressure potential? or are they the same? plz explain it clearly with examples
why does water move out of the phloem to enter the xylem in the sink?
give 3 difference between ascent of sap and translocation of food
wht is ringing or girdling experiments?
transpiration and photosynthesis compromise each other. Comment.
what are adhesive and cohesive properties in apoplast pathways?
why do dry seeds swell when they are placed in water??
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?
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?
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 Hydrophilic moiety ?
water channels made up of eight different types of aquaporins.what is the meaning of this statement?
Mention 4 uses of transpiration.
when concentration of external solution < concentration in cytoplasm the cell shrinks as it gives water to the external solution
which is correct?
in the study material it is given in the opposite way ,isn't it?
What is meant by apoplastic pathway?Why does it occur in cortex and not in endodermis?
Water enters a cell due to :
Explain pressure flow hypothesis of
translocation of sugars in plants.
define transpiration and guttation for 1 mark
wat is wall pressure for 1 mark
define apoplast ,symplast pathway for 1 mark
what are macro and micro nutrients ? give examples
how many ATP's are produced by 1NADH 2 FADH2 AND AEROBIC RESPIRATION
what is difference between guttation and dew?
WHICH OF THE FOLLOWING STATEMENT IS CORRECT ....1] PLANT ABSORB EXCESS QUANTITY OF WATER 2] PLANTS TAKE IN SMALL QUANTY OF MINERAL SALTS THROUGH SOIL WATER 3] WATER & INORGANIC SALT TAKEN IN SIMULTANEOUSLY BY ROOT HAIRS 4] PLANT ABSORB ONLY ONE THING AT A TIME WATER OR INORGANIC SALTS
