Plant Processes

How does water flow through a plant (from entry to exit)?

• stem-root-leaves

• leaves-stem-root

• root-stem-leaves

• root-leaves-stem

Which of the following describe transpiration best?

• Water enters the leaves of a plant as a liquid.

• Water exits the leaves of a plant as liquid.

• Water enters the leaves of a plant as a gas.

• Water exits the leaves of a plant as a gas.

What is it called when water sticks to water?

• Cohesion

• Adhesion

• Capillary Action

• Xylem

What is it called when water sticks to other items, like a xylem tube or penny?

• Cohesion

• Adhesion

• Capillary Action

• Glucose

When the forces of cohesion and adhesion work together, water can move up the plant against the force of gravity by....

• Phototropism

• Geotropism

• Photosynthesis

• Capillary Action

This force is created by water filling up the vacuoles, and gives a plant rigidity and shape so that it does not wilt.

• Photosynthesis

• Respiration

• Turgor Pressure

• Xylem

How are the processes of photosynthesis and respiration related?

• They both occur in the chloroplast.

• They both occur in the mitochondria.

• The products of respiration become the raw materials of photosynthesis.

• Neither benefit the plant.

In the tropical rainforest it rains daily, so which of the following would be most likely.

• The guard cells would close the stomata to conserve water.

• The guard cells would open the stomata so that transpiration could take place.

• The turgor pressure would be low because of the lack of water.

_______ slow down transpiration by _______ the stomata.

• Guard cells; closing
• Chloroplasts; closing
• Guard cells; opening
• Chloroplasts; opening

During photosynthesis, plants absorb energy from sunlight, they take in water from the soil using their roots, and they take in carbon dioxide from the atmosphere. What is produced in the leaves of plants, in addition to oxygen?

• sugar
• hydrogen
• minerals
• all of these
