4. The production of sperm cells is called?
7. The pairing of homologous chromosomes is called?
10. How many times does prophase, metaphase, anaphase and telophase occur in meiosis?
12. How many sperm cells are produced during spermatogenesis?
15. When part of a tumor breaks away and goes to a different part of the body.
16. The kind of cells produced during mitosis.
18. This is why crossing over is important in meiosis.
19. This is one of the threasons as to why cell division occurs. This is why you are not the same size as you were when you were a baby.
20. A tumor that has no serious effects on the surrounding tissues.

1. How many egg cells are produced during oogenesis?
3. The production of egg cells is called?
5. This is one of the threasons as to why cell division occurs. Examples include mitosis (asexual) and meiosis (sexual).
6. Four chromatids paired together during Prophase 1 of meiosis is called?
8. During prophase 1 of meiosis, the exchanging of genes in homologous chromosomes is called?
9. This stage of both mitosis and meiosis includes the cell growing and DNA being replicated.
11. Blood, skin and nerve cells are an example of this type of cell (meaning full sets of chromosomes).
13. The kind of cells produced during meiosis.
14. A group of diseases in which cells are growing out of control.
15. A tumor that interferes with the functions of surrounding tissues.
17. This is one of the threasons as to why cell division occurs. If you were to break a bone, cell division would occur to _____ the body.
