Under extreme cold the cell membrane will freeze and fracture also allowing the betalain to leak out into the extracellular. S Implemening and writing a good coursework project for. Capillary action lets water climb up to all the different parts of a plant through the xylem tubes in the stem. Visit the MindManager website, this map contains an invaluable guide to planning. Check out this project to see capillary action at work through a celerys xylem. And they also do not absorb UV light. Gradually, i know that the lipid bilayer of the beetroot will get denatured and the pigment betacyanin will leak out but whyhow would organic solvent allow the dye to leak from the vacuoles. This will allow the betalain to leak out from the cell vacuole. The reason why they leak out is because of the cell membrane structure. When the cell membrane is exposed to extreme heat the proteins unravel and the lipids melt. I am having trouble thinking about this. There is no indication that betalains protect plants from pathogens or herbivores..
