What is capillary action and what factors contribute to the ascent of sap in plants?
Understand the Problem
The question involves understanding the concept of capillary action in plants, particularly how water moves through the xylem. It explains the roles of cohesion and adhesion in this process.
Answer
Capillary action involves adhesion and cohesion, aiding sap ascent by root pressure, cohesion, adhesion, and transpiration.
Capillary action is the movement of water through narrow tubes due to adhesion and cohesion forces. It's crucial for the ascent of sap, which occurs due to root pressure, cohesion between water molecules, adhesion to xylem walls, and transpiration pull.

Capillary action is the movement of water through narrow tubes due to adhesion and cohesion forces. It's crucial for the ascent of sap, which occurs due to root pressure, cohesion between water molecules, adhesion to xylem walls, and transpiration pull.
More Information
Capillary action is essential for plants to transport water from roots to leaves, utilizing the cohesive and adhesive properties of water and xylem structure.
Tips
A common mistake is not recognizing the interaction between cohesion and adhesion in capillary action.
