- 6. bacteria
- 9. "cell eating" of large particles
- 10. bone
- 11. stage of cell division when the cytoplasm pinches and divides
- 12. process in which the chromatids of homologous chromosomes exchange strands of DNA (2 words)
- 13. sheets of cell that cover or line other tissues ( 2 words)

- 38. process by which the body produces new cell for growth and to replace worn out and damaged cells; results in two daughter cells that are identical to the parent cells
- 39. process by which the body produces new cells for reproduction; results in four cells that have half as many chromosomes as the parent cell
