Ok cool

I wrote about not letting water evaporate and the fact that it's transparent :smile:

I put it wouldn't have any guard cells or stomata, there would just be regular plant cells with the nuclei... There were 20 stomata right?

yeah its 20, i said it would have a waxy cuticle which reduces water loss

How do you obtain the dry mass of the potato...i wrote out it an oven and then measure on measuring scales but idk

I said that you could put it in a sucrose solution cos i thought if it was in a warm place it could react or decompose cos it was fresh? Maybe not, but i was just remembering the osmosis experiments
