SOL
LS.1 Conducting Investigations in Life Science.
LS.2 Cells
LS.13 Genetics
Objectives:
4-1 Cell Division and Mitosis
1. Explain why mitosis is important.
2. Examine the steps of mitosis.
3. Compare mitosis in plant and animal cells.
4. List two examples of asexual reproduction.
4- Sexual Reproduction and Meiosis
5. Describe the stages of meiosis and how sex cells are produced.
6. Explain why meiosis is needed for sexual reproduction.
7. Name the cells that are involved in fertilization.
8. Explain how fertilization occurs in sexual reproduction.
4-3 DNA
9. Identify the parts of a DNA molecule and its structure.
10. Explain how DNA copies itself.
11. Describe the structure and function of each kind of RNA.
This study guide is to help you learn the objectives for these units. As you do the following assignments, please WRITE YOUR ANSWERS ON LINED NOTEBOOK PAPER. The number in the parentheses tells you what objective the assignment is matched to above.
1) What is mitosis and how is it different in plants and animals? (1,3)
2) Give two examples of asexual reproduction in many-celled organisms. (4)
3) After the cell undergoes mitosis, how are the two new cells alike? (1,2)
4) Why happens to chromosomes before mitosis begins? (2)
5) Why is it important for the nuclear membrane to disintegrate during mitosis? (2)
6) How are sexual and asexual reproduction both alike? How are they different? (4,6)
7) What is a zygote and how is it formed? (8)
8) Give two examples of sex cells. Where are sex cells formed? (5)
9) Compare what happens to chromosomes during anaphase I and anaphase II. (5)
10) Plants grown form runners and leaf cuttings have the same traits as the parent plant. Plants grown from seeds can vary from parent plants in many ways. Suggest an explanation for why this can happen. (4,6)
11) How does DNA make a copy of itself? (10)
12) How are the codes for proteins carried from the nucleus to the ribosomes? (11)
13) A single strand of DNA has the bases AGTAAC. Using letters show a matching DNA strand for this pattern. (10)
14) How is tRNA used when cells build proteins? (11)
15) You begin as one cell. Compare the DNA in one of your brain cells to the DNA in one of your heart cells. (10)
