How plants transplant water!
Lily has been conducting experiments to see how plants transplant water. You can could clearly see the food dye has travelled up the stalk of the celery and the ends of the xylem vessels in the celery. The are like drinking straws!
If you want to see this in much more detail you could put a slice of celery under a microscope... If you don't have a microscope then have a look at this website! https://www.sciencephoto.com/media/141422/view/celery-stalk-light-micrograph
Well done Lily, this is a great experiment and an excellent way of seeing this process.
