Bio2 First Periodic Exam General Guide Questions for Review for GravPhoTruth

Plant Hormones

  1. What are tropisms? Give examples of these.
  2. Describe the roles of abscisic acid, auxin, cytokinin, ethylene, and gibberellin in regulating plant growth.
  3. Describe how the Darwin and Went experiments led to the discovery of auxin as the major factor behind phototropism.

Endocrine System

  1. What are hormones?
  2. Relate the function of the endocrine system with that of the nervous system.
  3. Differentiate between (+) and (-) feedback. Why are feedback mechanisms important in regulating hormone production?
  4. Why can hormones only affect specific cells and not others?
  5. Describe the role of hormones in invertebrates.
  6. Differentiate between the mode of action of a peptide/protein hormone vs that of a steroid/thyroid hormone.
  7. Why are signal transduction pathways important?
  8. Describe the role of the hypothalamus in the endocrine system.
  9. Describe the sources and functions of the hormones found in p.899 of your \m/ bio book.
  10. Describe the role of negative feedback in the regulation of thyroid hormones and maintenance of blood glucose levels.
  11. Describe the roles of the hormones (GnRH, LH, FSH, estrogen, progesterone) secreted by the hypothalamus, anterior pituitary gland, and ovary in regulating the female reproductive cycle.

Reproductive System

  1. Compare asexual and sexual reproduction and discuss advantages and disadvantages of each.
  2. Describe the different mechanisms of asexual reproduction (e.g. fission, budding, gemmules, fragmentation).
  3. Relate the choice of reproductive strategy with the availability of mates and resources, environment, and the lifestyle of the organism.
  4. Compare internal and external fertilization and discuss advantages and disadvantages of each.
  5. Enumerate the parts and describe the functions of the male and female reproductive systems.
  6. Compare the structure of the sperm cell with that of the egg cell.
  7. Describe the events that occur during fertilization.
  8. Describe the events that occur during development.

Mitosis and the Cell Cycle

  1. Enumerate the roles of cell division.
  2. Describe the events in the G1, S, G2, and M phases of cell cycle.
  3. Differentiate between the following: centromere, centrioles, centrosomes; chromatin and chromosomes; sister chromatids and daughter chromosomes; interphase, mitosis, cytokinesis.
  4. Differentiate mitosis in a plant cell from mitosis in an animal cell.
  5. Describe the G1, G2, and Spindle assembly checkpoints.
  6. Describe five factors that control the cell cycle.
  7. Describe the behavior of cancer cells.
  8. Enumerate the causes of and therapies for cancer.
