what is the difference between turgor pressure and pressure potential
what occupies space b/wcell wall & shrunken protoplast in plasmolysed cell?what wud be the pressure potential of flaccid cell? pls ans me!
Mention 4 uses of transpiration.
What is diffusion pressure deficit? (DPD)
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)
What would be the pressure potential of a flaccid cell? Which organisms other than plants possess cell wall?
Differentiate between Turgid, flaccid and Plasmolysed cells?
what is the difference between porins and aquaporins? plz explain properly the difference in function too.
why is osmotic pressure is positive and osmotic potential is negative??
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
describe the cohesive force theory of ascent of sap in plants.
What is hydrostatic pressure?What is the difference between positive and negative hydrostatic pressure?
What is the meaning of xylem lumen?
Define water potential .
Explain pressure potential . How is it build up???
What is meant by apoplastic pathway?Why does it occur in cortex and not in endodermis?
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?
What forces are involved in absorption of water from soil by root hairs?
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?
not dependent on the living system... means
differentiate between osmosis and plasmolysis
water channels made up of eight different types of aquaporins.what is the meaning of this statement?
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?
define imbibition.Is it a phenomenen of adsorption or absorption, explain.
what is the meaning of hydrophilic moiety...?
what is concentration gradient ?
what is difference between guttation and dew?
What would be the pressure potential of a flaccid cell??which organisms other than plants possess cell wall??
Why cell is called an osmotic system?
How many years it would take for the movement of molecules over a distance of 1m within a plant by diffusion alone?
Can you tell of any system in our body where pressure is built up?
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
wht is ringing or girdling experiments?
transpiration and photosynthesis compromise each other. Comment.
why do dry seeds swell when they are placed in water??
what does positive and negative pressure in xylem challens mean?plz explain clearly
give 2 reason why all mineral cannot be absorbed passively ?
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 occupies the space between the cell wall and the shrunken protoplast in the plasmolysed cell?
why does water move out of the phloem to enter the xylem in the sink?
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 cytoplasmic stream ?
what is Hydrophilic moiety ?
2. How does diffusion and facilitated diffusion depends upon solubility in lipids. ?
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 ??
Explain pressure flow hypothesis of
translocation of sugars in plants.
please explain the following terms and clearly point out the diff between them
what is the difference between turgidity and rigidity?
Could you please explain the difference between hypertonic and hypotonic solution .It is very urgent.
what are adhesive and cohesive properties in apoplast pathways?
