Question
Chapter 36, Problem 7TY
Summary Introduction
Introduction: The upper and lower parts of the leaf are different in terms of their internal structure. The differences arise to facilitate better photosynthesis and transcription. The palisade parenchyma is closer to the upper surface whereas the spongy parenchyma is closer to the lower epidermis of the leaf.

Determine the collective true-false status of the statements using the choices below.
I. In most eudicot leaves, large veins branch into a network of minor veins.;
II. A leaf’s lower surface usually has fewer stomata than the upper surface.;
III. A leaf’s upper surface typically receives the most direct sunlight may have a thicker cuticle than the lower surface.;
IV. Epidermal cells secrete a translucent, waxy cuticle that slows water loss.
None of the statements is true.
All statements are true.
Only three (3) statements are true.
Only one (1) statement is true.
Only two (2) statements are true.
Which of the following statements is incorrect?
a.
Vascular bundles are arranged in a ring in the outer parts of monocot stems in whereas in eudicots they are scattered throughout the stem.
b.
The cuticle is a hydrophobic layer that covers the aerial part of plants
c.
Vascular bundle arrangement is different in stem and root.
d.
The epidermis and periderm form the dermal tissue of plants.
Why do you think the upper cuticle of the leaf is thicker than the lower cuticle?
B. Look at a

will be in cros5-section. The stometa are justempty spaces on the
lower epidermis).
H. Examine radish seedlings. Use forceps to put a radish seedling on a slide without water or
coverslip. Examine it with a stereomicroscope. Note the "bottle brush" appearance of the root
hairs. (DEMO, SCope- follow the directions so the root hairs don't dessicate i.e, dry out)
