From personal experience, you may have noticed that cut flowers placed in a vase with tap water continue to be "alive" for several days. What is the most likely explanation as to why these cut flowers don't immediately wither and die?

Question

Cut flowers can still take up water through capillary action, which is the movement of water molecules through narrow tubes due to the forces of adhesion and cohesion. As water evaporates from the surface of the vase, it creates a negative pressure (or tension) that pulls more water up the stem of the flower. This process is known as an "evaporative pump" and can keep the flower hydrated for several days.
