Transpiration Lab

Transpiration

The loss of water vapor from a plant through microscopic pores called stomata on the plant's surface.

Stomata

Microscopic pores on the plant's epidermis that allow for gas exchange, primarily responsible for water loss during transpiration.

Guard Cells

Cells that regulate the opening and closing of stomata to control the exchange of gases and water vapor.

Xylem

Specialized vascular tissue responsible for transporting water from the roots to the leaves in plants.

Water Potential

The tendency of water to move from one area to another, with water moving from areas of higher potential to lower potential.

Cohesion

The property of water molecules sticking to each other through hydrogen bonds, aiding in the transport of water through the plant.

Hydrogen Bonds

Weak bonds between water molecules that contribute to the cohesive properties of water and its movement through the plant.
