Question
Chapter 28.3, Problem 2CC
Summary Introduction
To determine:
Whetherthe mesophyll of a plant species that has vertically oriented leaves could be divided into spongy and palisade layer.
Introduction:
A leaf comprises stomata for the exchange of CO2 and O2 between the surrounding air and inside the leaf. Stomata are the pores that can interrupt the epidermis of leaves. The entire area of stomata consists two epidermal cells: guard cells and mesophyll.
The mesophyll is a ground tissue of a leaf. Its middle layer is located between upper and lower epidermal layers. Mesophyll consist parenchyma cells for photosynthesis. The mesophyll cells have two distinct layers: palisade and spongy.

Lab 6- Vascular Plant Structures
What are the 4 main tissue types discussed (from the outline on p.127)
Know this terminology if asked to locate/identify the following: vascular cylinder, vascular
bundle, ground tissue, epidermis, palisade mesophyll, spongy mesophyll, guard cells, stoma,
xylem, phloem.
Can you determine if a plant is a monocot or dicot just by looking at the pattern of the roots?
The pattern of the veins in the leaf? The pattern of the vascular bundles in the stem?
Vascular plants evolved to have the apomorphic characteristics that enabled them
to grow with greater height and thrive with efficiency in sustaining more complex
structures.
Select one:
O True
O False
The sporophyte structure in vascular plants is dependent on the gametophyte
structure.
Select one:
True
False
The presence of lignin in the secondary cell wall structure of vascular plants acts as
a cementing agent between cellulose fibrils.
Select one:
True
False
