Question 1

Plant epidermal cells may form root and leaf hairs. What is the role of these structures?

Answer 1

They increase the surface area.

Question 2

To colonize terrestrial environments, plants developed many special adaptations. Discuss the importance of development of vascular tissue in this process.

Answer 2

-efficient transport of water and nutrients throughout the plant.
-transportation of food produced by the leaves to other parts of the plant.
- structure/support
-all allows the plant to live further away from water sources and grow taller.

Question 3

Compare vascular bundles arrangement in eudicots and monocotsl.

Answer 3

-vascular bundles form a ring around the outside of the stem in eudicots; vascular bundles are scattered throughout ground tissue in monocots
-phloem faces outward and xylem inward in vascular bundles in both monocots and eudicots

Question 4

Which of the following statements comparing roots, stems, and leaves in eudicots and monocots are true?

Answer 4

-monocots have fibrous roots with a poorly developed primary root and well-developed secondary roots.
-eudicots have well-developed primary roots
-monocots have scattered vascular bundles
-eudicots have vascular bundles form a ring around the stem
-monocots have netted venations
-eudicots have parallel venations
