Leaves
• ______________ is the process by which plants release excess water to evaporation.
• To regulate transpiration, the plant can open and close its __________.

Transpiration
stomata

Photosynthesis
• _______________ in the leaf absorb light (energy) from the sun.
• _________ absorb water from the soil.• ___________ allow carbon dioxide to
enter the leaf.• Through a chemical reaction, the
water and carbon dioxide are converted into sugar, oxygen and excess water.

• The tallest trees in the world, giant redwoods, grow up to 350 tall, but their roots are often only 10 feet deep.
• Redwoods tangle their roots together and give each other strength. They keep one another from falling over because of their own mass.
• What can we as people learn from the redwood trees?
