what occupies space b/wcell wall & shrunken protoplast in plasmolysed cell?what wud be the pressure potential of flaccid cell? pls ans me!
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 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 is the difference between turgor pressure and pressure potential
What would be the pressure potential of a flaccid cell? Which organisms other than plants possess cell wall?
describe the cohesive force theory of ascent of sap in plants.
what is the difference between porins and aquaporins? plz explain properly the difference in function too.
What is the meaning of xylem lumen?
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
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?
Differentiate between Turgid, flaccid and Plasmolysed cells?
What forces are involved in absorption of water from soil by root hairs?
What is hydrostatic pressure?What is the difference between positive and negative hydrostatic pressure?
In case sucrose does diffuse out through the membrane, will this equilibirium be ever reached? (this question haq been taken from NCERT Book Page no 181 para 1.
Define water potential .
Explain pressure potential . How is it build up???

Can you tell of any system in our body where pressure is built up?
biology textbook ncert on page 180 fig answer is b to a ryt?
Name two anti-transpirants
Transpiration is a necessary evil. It is necessary..understood...but how it is an evil?
differentiate between osmosis and plasmolysis

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?
