➢ 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).
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
3. Describe the basic characteristics, function and locations of the dermal tissue
system, the vascular tissue system, and the ground tissue system.
4. Name 3 basic plant organs.
5. 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?
6. What is the function of the roots? The stem? The leaf?
7. How are vascular bundles arranged in the stem of a dicot? How does that
differ from the arrangement in the root of a dicot?
8. What are the similarities between the vascular systems of roots and shoots?
9. Be able to recognize a microscopic image of a cross-section of a leaf and label
guard cells in the epidermis, parenchyma cells involved in photosynthesis,
vascular tissue viewed in cross-section and longitudinal section
10. Be able to identify the specific plant organs viewed in the grocery store botany
exercise.
11. Be able to recognize modifications to stems, leaves, and roots and suggest the
purpose of the modification (i.e. storage, protection from herbivory, etc.)
SEEDLESS PLANT LAB
1. What does the word root –phyta mean? Why do all plant taxa end in this?
2. Know the life cycle that all plants exhibit. Be able to draw and discuss it in terms
of the processes and structures involved. Be able to recognize the structures and
processes of the life cycle in each of the 4 plant phyla discussed this week.
3. What does heteromorphic alternation of generation mean?

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. Why do all plant taxa end in this: know the life cycle that all plants exhibit. Be able to draw and discuss it in terms of the processes and structures involved. What type of life cycle does selaginella (= phylum. Note: gymnosperms and angiosperms are common names, not phylum names. Draw and label the components of a male and female strobilus (=cone). Draw and label the parts of a pine pollen grain. How many are present on each scale of the female cone in.
