3. Answer: No Why? Cells divide and the amount of cells increases

4.  Reproduction  Growth  Repair

5.  Each new cells, called a daughter cell is genetically identical to the parent cell

6.  Chromatin = unwound coils of DNA  Chromatid = made up of genetic material  Chromosome= two chromatids joined together  Centromere= center of the chromosome- holds chromosomes together

7.  Centriole = anchors cell during division (plants do not have this)  Homologous Chromosomes = similar chromosomes paired together  Humans = 23 pairs = 46 total

8.  Humans: 46 chromosomes 23 homologous pairs 92 chromatids  Diploid = # of chromosomes of that species  Haploid = half the number chromosome #

10. Mitosis = a cell process in which the nucleus divides to form two nuclei identical to each other.

11. DNA replicates Organelles double in number What happens

12. DNA forms chromosomes Spindle forms Centrioles move toward opposite poles What happens

13. Chromosomes line up in the middle of the cell “equator” What happens

14. Chromatids separate and move to opposite poles What happens

15. Nuclear membrane forms around each group of chromosomes Chromosomes unwind What happens

16. Cytoplasm divides One cell becomes 2 cells

18.  Uncontrolled cell division  No one fully understands how cancer is formed Characteristics of Cancer Cells Cell growth is uncontrolled These cells do not function as a part of the body The cells take up space and interfere with normal bodily functions The cells travel throughout the body The cells produce tumors and abnormal growths anywhere in your body

19.  Genetics  Smoking  Exposure to chemicals  Radiation  Viruses

20.  By doctors looking at cell tissue

21.  Surgery to remove cancerous tissues  Radiation with X-rays to kill cancer cells  Chemotherapy = the use of chemicals to destroy cancer cells  Early detection
