The cohesion-tension theory explains the translocation of water by the process of transpiration. This theory was proposed by Dixon and Jolly and is popularly known as Cohesion-tension transpiration pull model of water transport. This pull helps in water transport from roots to the leaves. Less than one per cent of water is utilised in photosynthesis and plant growth. Most of the water is lost by transpiration through stomata. Cohesion keeps the water molecules stick together and adhesion allows the water molecules to stick to the xylem walls.

In a resting axon, the inside is negatively charged while the outside is positively charged. The cell has a voltage of -70 millivolts. In this situation, we say the membrane has a resting potential. When the neuron needs to send an electrical signal, it does this by opening channels. Ions rush into the cell, leading to depolarization of the membrane. Then channels open, ions rush out, and the cell is repolarized.
