| A | B |
| cell cycle | life cycle of a cell |
| DNA | genetic material that controls the cell activitiess |
| human body cells | have 46 chromosomes |
| cell cycle stages | interphase, mitosis, cytokinesis |
| interphase | cell grows & copies DNA and organelles |
| interphase | longest part of the cell cycle |
| mitosis | the cell's nucleus divides into two new nuclei |
| 4 phases of mitosis | prophase, metaphase, anaphase, telophase |
| prophase | DNA forms chromosomes, nuclear membrane disappears |
| metaphase | chromosomes line-up in the middle |
| anaphase | chromatids separate |
| telophase | two new nuclei are formed |
| chromatids | single rods of DNA |
| chromosome | double rods of DNA |
| centromere | the piece that holds chromatids together |
| cytokinesis | two new cells are formed when cytoplasm divided |
| replication | process of copying DNA |
| gamete | egg or sperm |
| diploid | contains full set of chromosomes |
| haploid | contains half the number of chromosomes as body cells |
| meiosis | cell division that results in 4 haploid cells |
| cell plate | structure that forms in plant cells during cytokinesis |
| spindle fiber | structure produced by centrioles that holds chromosomes in place during division |
