13B Plant Anatomy (H)

What is the main function of epidermal hairs?

• They are antiherbivorous

• They may contain toxins

• They help the plant absorb water and CO2

• They regulate the size of the stoma

How do the guard cells regulate the size of the stoma?

• "muscle" like tissues

• turgor pressure

• nerve fibers

• solute concentrations within the guard cells

Ground tissues consist of which of the following cells?

• upper and lower epidermis

• palisade and spongy mesophyll

• xylem and phloem

• guard cells and stoma

The spongy mesophyll is primarily a storage area for

• oxygen and water.

• oxygen and carbon dioxide.

• carbon dioxide and water.

• water and minerals.

Which of these is NOT a plant tissue?

• leaf

• ground

• vascular

• dermal

Where would you most likely find the most cells going through mitosis and cytokinesis?

• ground tissue

• meristematic tissue

• root hairs

• epidermis

How many compound leaves do you see?

• 1

• 2

• 3

• 4

• All of them are compound

Which of the following specifically brings glucose (sugar) and nutrients to the roots?

• xylem

• phloem

• petiole

• roots

WHY does a plant not allow the stoma to be open all of the time?

• Too much carbon dioxide would leave the leaf.

• Water loss would be a problem.

• Oxygen would escape.

• None of these answers.

How would you most accurately describe the venation of this leaf?

• palmate netted venation

• parallel monocot

• pinnate netted venation
