Can you tell of any system in our body where pressure is built up?
what occupies space b/wcell wall & shrunken protoplast in plasmolysed cell?what wud be the pressure potential of flaccid cell? pls ans me!
why is osmotic pressure is positive and osmotic potential is negative??
What is diffusion pressure deficit? (DPD)
what is positive hydrostatic pressure gradient and a negative hydrostatic pressure gradient
Why Lipids are not strictly macromolecules ??
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?
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 does this statement mean:
"Diffusion in solids rather than of solids is more likely."
WHAT ARE PORINS.WAHT IS IT FUNCTON
What is the meaning of xylem lumen?
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
describe the cohesive force theory of ascent of sap in plants.
Differentiate between Turgid, flaccid and Plasmolysed cells?
What is hydrostatic pressure?What is the difference between positive and negative hydrostatic pressure?
What forces are involved in absorption of water from soil by root hairs?
Define water potential .
Explain pressure potential . How is it build up???
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?
biology textbook ncert on page 180 fig answer is b to a ryt?
what would be the pressure potential of a flaccid cell?
Why cell is called an osmotic system?
Transpiration is a necessary evil. It is necessary..understood...but how it is an evil?
How many years it would take for the movement of molecules over a distance of 1m within a plant by diffusion alone?
differentiate between osmosis and plasmolysis
water channels made up of eight different types of aquaporins.what is the meaning of this statement?
not dependent on the living system... means
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 is concentration gradient ?
What would be the pressure potential of a flaccid cell??which organisms other than plants possess cell wall??
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
Which one of the following is correctly matched?
give 3 difference between ascent of sap and translocation of food
define imbibition.Is it a phenomenen of adsorption or absorption, explain.
wht is ringing or girdling experiments?
Could you please explain the difference between hypertonic and hypotonic solution .It is very urgent.
transpiration and photosynthesis compromise each other. Comment.
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 ) ??
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?
what does it ment by HIGH TURGOR PRESSURE and LOWER TURGOR PRESSURE?/
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?
transpiration causes loss of water but how come it cools down the temperature of the leaf? plz explain...
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 ?
why does the green plants start evolving co2 instaed of oxygen in a whole summer dahuryyyyyyyyyyy fasty?
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?
what is the difference between turgidity and rigidity?
