THE PROCESS OF TRANSPIRATION

DURING TRANSPIRATION

• Transpiration is the process of water traveling through a plant and evaporating.
• Transpiration is part of the water cycle - evaporation.
• One way to remember transpiration is transportation. Transportation is moving someone or something from place to place, and transpiration is the process of moving water from place to place in a plant.

STEPS 1 AND 2

• Step 1: Water from the ground is enters through the roots
• Step 2: The water enters and travels through the xylem, which is a tube-like structure that carries water through a plant.

STEP 3 AND 4

• Step 3: The water flows through the stem
• Step 4: The water travels through and disperses among the leaves

STEP 3 AND 4

• Step 5: Water enters the stomates, which are little openings on the leaves that allow gases and water vapor to enter and leave the leaf, and the stomates are guarded by guard cells, which control the openings and closings of the stomates to regulate transpiration.
• Step 6: The water leaves the leaf in the form of water vapor.

REVIEW

• The process of transpiration: Roots, xylem, stem, leaves, stomates and guard cells, and water vapor (leaves the plant)
• Transportation = Transpiration
