Ø (Note: There is no answer key. All of this material is drawn directly from your
lab exercises, lab manual or textbook so you should be able to go back and

Ø I have attempted to cover the most important points here. This list may not be
exhaustive. Remember, if the material is in your lab manual or your lab
manual refers you to pages in your text, it is fair game for the lab exam.
PLANT ANATOMY LAB
1. Recognize the 3 basic types of cells and the differences between them (p. 43).
The three different types of cells are Collenchyma, Parenchyma, and Sclerenchyma
Collenchyma: are the cells with the thickened corners near the ribs (outer surface of the stalk)
Parenchyma: the relatively thin walled cells that make up the bulk of your cross section
Sclerenchyma: the cap of heavily thickened cells found to ne side of the vascular bundles
2. Be able to identify the following structures and locate and label them on a
diagram:
○ Leaf blade
○ petiole
○ node
○ internode
○ axillary bud
○ primary root
○ lateral root
○ flowers
○ vascular tissue
○ ground tissue
○ root cap
· simple issues
· complex tissues
· xylem
· phloem
· epidermal tissue
· stomata
· guard cells
· meristems
· leaf primordia
· trichomes
· root hairs
1. Describe the basic characteristics, function and locations of the dermal tissue
system, the vascular tissue system, and the ground tissue system.
2. Name 3 basic plant organs.
Answer: Roots, Stems & Leaves
3. Name 2 types of meristems that can be found in a woody plant. Where are they
found in the plant? What is their function? What do they give rise to?
4. What is the function of the roots? The stem? The leaf?
Answer: Function of roots- absorption of water and inorganic nutrients, anchoring the plant to
the ground and giving it support & storage of nutrients and food.
Function of the stem- supports leaves and branches, transports water between roots
and leaves & may be able to store materials necessary for its survival
