Terms | Definitions |
|---|---|
 asexual reproduction | type of reproduction with 1 parent and offspring are genetically identical; examples - binary fission, budding, vegetative |
| sexual reproduction | type of reproduction with 2 parents and offspring are genetically diverse/different |
| binary fission | type of asexual reproduction; common in bacteria; cell splits into 2 new cells of equal size that are genetically the same |
| budding | type of asexual reproduction; common in hydra and yeast; minature version of parent grows genetically the same and separates |
| vegetative reproduction | type of asexual reproduction; common in plants |
| mitosis | cell division that takes place in eukaryotic cells; chromosome number stays same; ex: 2n -- 2n; think "toes" since toes are part of your body and mitosis is reproduction of body cells |
| meiosis | process that leads to formation of genetically different gametes (sex cells like sperm and egg); crossing over happens; chromosome number reduced by half; ex: 2n -- n |
| fertilization | process where sperm and egg unite during sexual reproduction and form a zygote; ex: n + n = 2n |
| body cell | any cell that IS NOT a sex cell; ex: skin cell; hair cell; muscle cell; bone cell; wing cell |
| sex cell | also called gametes; only have single set (n) of chromosomes; used in sexual reproduction during fertilization to form a zygote |
| gamete | also called sex cell; ex: sperm and egg; have single set (n) of chromosomes |
| zygote | 2n cell that forms after fertilziation when sperm and egg unite |
