The reading for this unit is not found in your book and will be supplied to you when we start the unit.

By the end of the unit you should have the following completed:

1.     Be able to define and give an example when appropriate of: 

Group A: asexual reproduction, fission, binary fission, budding, regeneration, spores, vegetative reproduction, runners, grafting, conjugation, sexual reproduction,

Group B:  meiosis, haploid, diploid, gametes, chromatid, Interphase I, crossing over, Prophase I, Metaphase I, Anaphase I, Telophase 1, Meiosis II, sperm, oocytes, ova (ovum), fertilization,

Group C:  hypothalamus, pituitary gland, hormone, feedback system, estrogen, FSH, LH, testosterone, progesterone, menopause

2.     All sections of the reading should be read with the goal of being able to discuss/explain the information contained in them.  NOTE:  The reading is not in your book and will be supplied to you with these expectations.

3.     Have the following concept review questions completely answered:

Group 1 Types of reproduction

1. What is the main difference between sexual and asexual reproduction?

2. What are the main types of vegetative reproduction?

3. How is vegetative reproduction different from regeneration?

4. If you are a member of a species that is on the brink of extinction, why is it good to be able to reproduce both sexually and asexually?

5. Why isn’t conjugation considered sexual reproduction?

Group 2 Genes, Chromosomes and numbers

1. What types of cells in an organism’s body are diploid?

2. What types of cells in an organism’s body are haploid?

3. Do paramecia have haploid cells?

4. If an organism has 11 chromosomes in its gametes, how many does it have in its body cells?

5. Suppose there are two similar plant species—one that reproduces only by sexual reproduction, and one that reproduces only by asexual reproduction.  Which species has a batter chance of surviving over the next one million years?  Give a reason for your answer.

6. Suppose you find a cell that contains 15 chromosomes.  Is this cell a gamete or a body cell?  Give a reason for your answer.

Group 3 Phases of Meiosis

1. Compare and contrast the events that occur in the nucleus of a cell when it is in Prophase of mitosis and Prophase I of meiosis.

2. What is the function of polar bodies in females?

3. Why are polar bodies formed in female meiosis and not in male meiosis?

4. How is the final product of meiosis different in males and females?

5. Why does this difference occur?

Group 4 Hormonal control of Reproduction.

1. Which hormones are important to the human reproductive system in males.

2. What is the origin of LH, FSH, testosterone, progesterone, and estrogen?

3. What is the function of LH, FSH, and testosterone in males?

4. What is the function of LH, FSH, progesterone, and estrogen?

5. If an ovum can be fertilized only during a 24-hour period, how can it occur even when a female does not engage in intercourse during this period?

 6.  If only one sperm can fertilize the ovum, why are hundreds of millions sent?

4.  Labs to be handed in with discussion questions written out and answered in complete sentences:

Types of Reproduction Lab                            Meiosis Activity

5.     Know how to convert from one unit to another in the metric system using factor label method.  You will have 3 on your test.

6.     Know what the metric prefixes mean and be able to apply their meaning in a mathematically problem.

7.     Be able to compare and contrast meiosis and mitosis

8.     Be able to explain the hormonal feedback system that controls a woman’s menstrual cycle.

9.     Know all material covered in class notes.

  Extra Credit: To be passed in before the test is taken  (maximum 3 pts on test)

Is human reproduction lacking in seasonality?  Record by months the birthdays of members of your biology class and as many other classes as possible.  Present the data in the form of a bar graph. Write a one page well constructed report that presents your data, interprets it and gives reasons for the interpretation.  Your paper should be typed, 12 pt. Font, with margins no greater than one inch on any side.
