Describe how the capillary action of water works in the xylem of a plant.
What is water is cohesive & adhesive which allows it to stick to itself and the walls of the xylem, transporting up from the roots to the top areas of the plant?
Describe the Tyndall effect for salt water versus muddy water.
What is the particles in salt water are too small and the light cannot scatter, thus no light is seen in the solution; in muddy water, the particles are large enough to scatter the light, which can be seen in the suspension?
