What is the importance of surface tension and capillarity in the lives of living organisms?
HUDGE project dieing here lol
Answers:
I'm not one hundred per cent sure, but I think what keeps a pond skater above the surface of the water is surface tension. You might want to check that, or if you don't think it's important, just ignore it.
Capilliarity is to do with plants. I don't know how to explain it exactly so I'll suggest an experiment. Take a piece of capillary tubing and dip one end in a small pool of water. It looks as though water is being sucked up the tube. Really water is adhering to the sides of the tubing and that's what pulls it up, but it can only go so far. Its one of three routes thought to take water from the roots, up the xylem. The other two routes are the cohesion tension theory and root pressure.
Is this a good start?
It is all about blood flow, but you probably knew that much.
