Question

If a plant cell is put in a beaker in such a conditions that :

1) the conc. of water in cell < the conc. of water in beaker


Will the cell swells up ? shrinks ? or nothing happens to it ?

Answer 1

@Callisto please help me

Answer 2

Answer 3

Sorry, I haven't taken Biology for my senior secondary school...

Answer 4

:( .. do you know any1 who is good in biology ?

Answer 5

any help @apoorvk ?

Answer 6

Hmm. some thing to do with tonicity - since the cell has a higher concentration of the solute - (it's hypertonic), it will absorb water to become isotonic with its surroundings (ofcourse provided the cell-membrane is semi-permeable).

Answer 7

@mathslover
The cell will swell.

The given solution is a hypotonic solution in which the concentration of water is less in the cell than that outside. So the water will come into the cell through osmosis.

So, the cell will swell.

Answer 8

Thanks @apoorvk

Answer 9

But .. the cell is PLANT CELL ..
PLANT cell has CELL WALL .. Hence cell wall will not allow any1 to enter the cell right ?

Answer 10

Oh sorry : cell wall is semi permeable

Answer 11

But in my book there are 2 questions given :

if a cell is plant cell then what will happen and if the cell is animal cell then what will happen ?

this means the answers will be diff.

Answer 12

actually that is not so.......................

plant cell wall is a FULLY PERMEABLE MEMBRANE.............. according to my knowledge

so it will allow even the flow of sugar inside the cell to outside and water from inside to outside........

animal plasma membrane is SEMI PERMEABLE MEMBRANE..................

so it will NOT allow the flow of sugar from inside to outside and will only permit the flow of water into the cell........

got that ?

Answer 13

Hmn but what about this ?

Answer 14

I have written the DIFF. answers in the last comment///

Answer 15

Oh sorry i got it now ..

Answer 16

np............

Answer 17

actually plants have cell walls made of cellulose outside the semi-permeable cell membrane, whereas animal cells only have the s/p cell-membrane.

Thanks @apoorvk ..
