12. What kinds of organisms reproduce asexually? Give examples.
13. Compare and contrast asexual reproduction and mitosis.
14. Put the following words in order from least to greatest: organ, cell, tissue, organism, organ system
15. What is cell differentiation? What determines how a cell in an embryo will differentiate?
Chromosomes and Meiosis Chapter 6 Sections 1, 2, and 6
You have body cells and gametes.
Do gametes come from germ cells or somatic cells?
__________________________________________________________
Your cells have autosomes and sex chromosomes.
If a person’s pair of sex chromosomes is XY, is the person male or female?
__________________________________________________________
Body cells are diploid; gametes are haploid.
What is the difference between the cells that result from mitosis & the cells that result from meiosis? Which process
do gametes come from? Which process do somatic cells come from?
___________________________________________________________

2. A body cell ___________________________
3. An egg or sperm cell ________________________________
4. Any chromosome except a sex chromosome _____________________________

The Big Picture
5. If a diploid cell with 8 chromosomes goes through meiosis, how many chromosomes will the resulting
haploid cells have? If a haploid cell has 9 chromosomes, how many chromosomes does the diploid cell
have? How many chromosome pairs are in a cell with a diploid number of 20?
6. Circle the sex of a person with the sex chromosomes XX: male / female
7.
What do 1, 2, and 3 correspond with in the diagram to the left?
Process of Meiosis
Cells go through two rounds of division in meiosis.
BE SURE YOU CAN RECOGNIZE THE STAGES OF MEIOSIS

Haploid cells develop into mature gametes.
How do mature gametes differ from the immature haploid cells?
