Question

How do plants use capillary action?

Answer 1

EXPLANATION:

1. If you put a fine-tipped straw into a glass of water, you can see that the water has risen to the top of the straw and is now higher than the water level in the glass. The straw seemed to have risen against gravity. We refer to this as capillary action.
2. Plants use capillary action to bring up the water through the root and send it through the stem and branches. The molecules of water are attracted to the molecules inside the stem.
3. Adhesive force contributes to capillary action, which causes a liquid column to rise inside a tiny capillary tube.
4. The formula for the capillary rise,

$h=\frac{2S\cos \theta }{\rho rg}$, where $h=$height, $S=$surface tension, $\rho =$density, $r=$radius, $\theta =$angle of contact, and $g=$gravity.
