Chapter 3

1. Be familiar with the 3 types of tissues, their component structures and their functions.
2. Be familiar with the 3 types of cells within ground tissue, their structures and functions.
3. Be familiar with the plant organs, their structures and the function of each.
4. There may be a diagram for you to label on a x-section of a leaf or a stem.
5. Know the modified above- and below-ground stems, and their functions.
6. Be familiar with specialized roots, and their non-plant “helpers” (mycorrhizae and Rhizobium).

Chapter 5

1. Be familiar with the parts of a flower, especially the 4 whorls, and the function of each.

2. Be familiar with the evolutionary role of the flower.

3. Know the difference between perfect/imperfect/complete/incomplete/monoecious/dioecious flowers and plants, and how they may pertain to pollination.

4. Be familiar with the processes of pollination and fertilization (double fertilization).

5. Know the importance and uniqueness of double fertilization and its unique product.

6. Know the floral characters of different pollination strategies. E.g. Describe a flower that has long been pollinated by hummingbirds. Refer to corolla shape, color, fragrance, etc.

7. Be prepared to label a diagrammatic flower.

Chapter 6

1. Be familiar with the evolutionary role of the fruit.

2. Know the difference between the botanical and “supermarket” definition of a fruit.

3. Be prepared to label the parts of the pericarp.

4. Know the types of dry and fleshy fruit mentioned in class, and their characteristics.

5. Be familiar with the different dispersal mechanisms of fruit, and how they work.

6. Be familiar with the relationship of the fruit with its dispersal strategy. E.g A fruit that had air sacs around its seed would most likely be dispersed by what means?

7. Why do fruits need to be dispersed?

8. Know some of the cues fleshy fruit impart when ripe, and why this is important to the fruit.

Chapter 7

1. Know the genetic terms we went over in class.

2. Know monohybrid and dihybrid crosses, and be prepared to do a Punnett Square on one of them.

3. Be prepared to explain the principles of dominance, segregation, and independent assortment.

Chapter 8

1. Know the characteristics of taxonomic hierarchy (or ranking). (I don’t expect you to memorize all the rungs in the hierarchy, from species to kingdom, but I do expect you to be very familiar with genus and species). The characteristics refer to inclusiveness/exclusiveness, shared characters/variable characters, etc. as you move up the ladder.

2. Be familiar with the importance of scientific naming (nomenclature).

3. Know the difference between binomials and polynomials, and the advantages of the former.

4. Read about Linnaeus in the text.

5. Why are scientific names Latinized?

6. Know the pitfalls of common names for plants.

7. Be familiar with Darwin’s concept of natural selection, and the importance of variability.

8. The 4 underlying premises to Darwin’s theory of evolution by natural selection. (Needn’t memorize them, just understand them).

9. There might be a short answer question linking Mendel’s transmission of traits (inheritance) with Darwin’s natural selection and plant nomenclature.

1. There may be some questions on the exam taken from discussions in the field.
