    What happens if you cover the top of a leaf in petroleum jelly? (Transpiration) and same to the bottom of the leaf.

    please help

    what is transpiration? loss of water from top and taking up water from the bottom thanks to that.

    the jelly prevents water movement

    what happens if you cant lose water (top) and cant take up water (bottom).

    does the transpiration stream stop at any point? does the plant lose too much water at any point? could the plant wither and die? stress responses? do stomata close to reduce water loss?
Have you ever experienced racism/sexism at uni?
