Question 12

Plants are able to use sugars and other compounds as energy sources through what process?

Answer 12

Question 13

The loss of water as vapor from plant leaves through tiny openings in the leaves (aka stomates) is what process?

Answer 13

Transpiration

Question 14

What is the most functional tissue within the stem?

Answer 14

Vascular Tissue

Question 15

Hormones are chemicals produced in one part of a plant and translocate to another location in the plant where they….

Answer 15

Control plant growth.

Question 16

Why is it necessary to select plants that belong to an appropriate hardiness zone?

Answer 16
