Plasmolysed plant cell - quick question

simcard2007

Hi there, I have a quick question for any willing biologist, my teacher told us to research this in advance of some tests we are going to do.

In a plasmolysed plant cell, when the plasma membrane has pulled away from the cell wall, what occupies the space between the cell wall and membrane?

Thanks.

i think its mainly salts and amino acids. i'm not 100% sure though, but it's worth a shot...

OK thanks for the reply.

Just to clarify, say a piece of plant tissue is placed in a concentrated sugar / salt solution.

The water leaves the plant cells due to osmosis etc. etc. and the plant cells become plasmolysed.

There is now a 'space' between the cell wall and membrane which previously didn't exist... what is it?!

Thanks.

Gases?

in this instance, the 'space' is filled with the concentrated sugar/salt solution as the cell wall is permeable.
