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)
why is osmotic pressure is positive and osmotic potential is negative??
what is positive hydrostatic pressure gradient and a negative hydrostatic pressure gradient
What does this statement mean:
"Diffusion in solids rather than of solids is more likely."
explain the process of photosynthesis in detail.(please)
Can you tell of any system in our body where pressure is built up?
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 pressure potential
what is the difference between porins and aquaporins? plz explain properly the difference in function too.
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
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???
water channels made up of eight different types of aquaporins.what is the meaning of this statement?
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?
not dependent on the living system... means
what is imbibition?
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 the meaning of xylem lumen?
biology textbook ncert on page 180 fig answer is b to a ryt?
what is concentration gradient ?
what would be the pressure potential of a flaccid cell?
What is meant by apoplastic pathway?Why does it occur in cortex and not in endodermis?
Transpiration is a necessary evil. It is necessary..understood...but how it is an evil?
teacher , my book says that, diffusion pressure of water or any solvent in a solution is always less than the diffusion pressure of pure water or solvent. wht is the reason fr this?
say for example i have 500ml of water on one side and 500 ml of water with salt dissolved in it on other side. now the volume of water on both sides is same. is the Diffusion presssure of pure water still greater than the other?
if yes , how?
differentiate between osmosis and plasmolysis
Why Lipids are not strictly macromolecules ??
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...?
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
give 3 difference between ascent of sap and translocation of food
Mention 4 uses of transpiration.
why does the water potential increases when applied pressure is greater than the atmospheric pressure in a pure water?
wht is ringing or girdling experiments?
If water enters in a cell, the pressure exerted by its swollen protoplast is :
transpiration and photosynthesis compromise each other. Comment.
why do dry seeds swell when they are placed in water??
what is the meaning of gradient?
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?
When is a cell said to be flaccid?
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 inhibitors?
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 cell is called an osmotic system?
what is Hydrophilic moiety ?
describe the cohesive force theory of ascent of sap in plants.
Explain pressure flow hypothesis of
translocation of sugars in plants.
what is difference between guttation and dew?
what is the difference between turgidity and rigidity?
why do plants die in water logged areas ??
is it coz there is a higher concentration of water in soil than minerals leading to reduction of active transport of minerals from soil to the plant ??
