Questions & Step-by-Step Solutions
What is the main driving force for the movement of water through the xylem?
Step 1: Understand that xylem is a part of a plant that transports water from the roots to the leaves.
Step 2: Know that water is lost from the leaves through a process called transpiration, which is when water evaporates into the air.
Step 3: Realize that when water evaporates from the leaves, it creates a pull or suction effect that draws more water up from the roots through the xylem.
Step 4: Conclude that this 'transpiration pull' is the main force that moves water through the xylem.
