| A | B |
| cell cycle | series of events cells go through as they grow and divide |
| mitosis | actual cell division |
| cytokinesis | division of the cytoplasm |
| chromatid | half of a chromosome |
| centromere | located at the middle of the chromosome, holds the chromatids together |
| interphase | period of growth and synthesis before the cell divides |
| centriole | organelle used by animal cells during cell division |
| spindle | forms around the centrioles and pulls chromatids to the poles of the cell |
| homologous | two sets of chromosomes, one from each parent |
| diploid | same amount of DNA as parents |
| haploid | half the amount of DNA |
| tetrad | four chromatids, forms during meiosis |
| corssing over | exchanging portions of chromatids during prophase I |
| gamete | sex cell, egg or sperm |
| cleavage furrow | forms between the cells during telophase/cytokinesis in animal cells |
| cell plate | forms between cells during telophase/cytokinesis in plant cells |
| chromatin | the form DNA takes before cell division |
