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)
why is osmotic pressure is positive and osmotic potential is negative??
what is positive hydrostatic pressure gradient and a negative hydrostatic pressure gradient
what is the difference between turgor pressure and pressure potential
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
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 is meant by apoplastic pathway?Why does it occur in cortex and not in endodermis?
Differentiate between Turgid, flaccid and Plasmolysed cells?
Can you tell of any system in our body where pressure is built up?
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???
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 concentration gradient ?
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?
Transpiration is a necessary evil. It is necessary..understood...but how it is an evil?
What is the meaning of xylem lumen?
Why Lipids are not strictly macromolecules ??
differentiate between osmosis and plasmolysis
A farmer observed drops of water along the margins of leaves of tomato plant, growing in his well-watered field on a winter morning.
i) Name this process.
ii) Give reasons for this occurance.
what is adsorption?
whats the difference between turgor pressure and pressure potential? or are they the same? plz explain it clearly with examples
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?
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??
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
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 plasmolysis and osmosis?
answer in tabular form please
what is the difference between turgor pressure and wall pressure?
What forces are involved in absorption of water from soil by root hairs?
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 ?
what is imbibition??..
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?
Explain pressure flow hypothesis of
translocation of sugars in plants.
why trasport of water and minerals from xylem is unidirectional while of organic and mineral nutrients through the phloem: Multidirectional?
what is difference between guttation and dew?
what is the difference between turgidity and rigidity?
why does the water potential increases when applied pressure is greater than the atmospheric pressure in a pure water?
