Leaves

• ______________ is the process by which plants release excess water to evaporation.

• To regulate transpiration, the plant can open and close its __________.

• [Answer this question] Compare the transpiration process to humans. What could you compare it to?

Transpiration

stomata

• [Answer this question] The stomata also release oxygen and take in carbon dioxide. What human process is this like?

• ______________ is the process by which plants burn food to release its energy.Respiration

Leaves

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.

Roots

• Roots _______ the plant to the ground and absorb water and nutrients from the soil.

• Plants with a single thick root with tiny hair-like roots coming off of it have a _______ root system. A carrot is an example of this type of root.

• Plant which have many roots branching in all directions have a _________ root system. Many trees have this type of root system.

Which of these of these pictures is a taproot pictures is a taproot

system and which is a system and which is a fibrous root system?fibrous root system?

Draw a picture of each of the types of root systems in your

notebook.

• 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?
