How do plants drink water?

Selecione uma das seguintes:

  • Plants absorb water that rains from the sky through a process called absorption.

  • Plants drink water and it travels up the stem through a process called capillary action.

  • Water travels through the stem by a magnetic pull.

How does capillary action occur?

Selecione uma das seguintes:

  • There is a chemical action between the stem molecules and the water molecules that allow for them to create and exchange energy.

  • Water accumulates in the stem and so the water level gets higher within the stem.

  • Water molecules stick together and to the walls of the tube as they are climbing up the stem. They will continue to climb until gravity is too much.
