Plant transport and leaf anatomy

What does xylem transport?

• Water and minerals

• Water only

• Sugar

• Food

Which of the following does NOT affect rate of transpiration?

• Water in the soil

• Temperature

• Amount of sunlight

• Wind

What do the guard cells do?

• Control active transport

• Control nutrients moving into the cell

• Controls the rate of transpiration (loss of water through the leaf)

Water and minerals move in which direction within the plant

• Upward

• Down

What does phloem transport?

• Water

• Minerals

• Fruit

• Sugar

Where does sugar transport begin?

• Roots

• Leaves

• Root hairs

• Vascular bundles

Structures represented in the illustration below are found in the lower epidermis of a plant leaf. The illustration at the right shows the response to a certain environmental condition.

The response represented in the illustration would most likely be caused by-

• a reduced supply of oxygen

• long periods of rainfall

• high concentration of glucose

• little available water

Students are instructed to place leafy celery stalks into color water in a beaker overnight. The following day, the students observed the color of the celery leaves changed from green to red. The students cut across the edge of the celery and observed the small tube openings along the edge are also red.

How do the plant systems work together to make the movement of the liquid possible?

• The roots absorb the water, minerals move up the stem, while the stem moves food produced in the leaves down to the roots.

• The roots anchor the plant into the soil and the stem holds the leaves up.

• The roots absorb their own water and minerals and the leaves push out CO2.

• The roots lose water vapor to the soil and the stem loses water vapor through the leaves.
