Water Properties and Plant Processes

The video tutorial covers the concepts of water and polarity, focusing on key vocabulary such as cohesion, adhesion, surface tension, and capillary action. It explains how polar molecules have positive and negative regions, leading to hydrogen bonding. Cohesion refers to water molecules bonding with each other, while adhesion involves water bonding with other polar substances. Surface tension results from cohesive forces at the liquid's surface, allowing small organisms to move on water. Capillary action, an example of adhesion, enables water movement in plants, crucial for photosynthesis. The video concludes with a review of these terms and their biological significance.
