| Reproduction that involves only one parent and results in genetically identical offspring | asexual reproduction |
| One-celled organism, spherical, spiral or rod-shaped. Various species involved in fermentation, infectious disease or nitrogen fixation | bacteria |
| The exchange of reciprocal segments of DNA by homologous chromosomes at the beginning of meiosis; source of genetic recombination | crossing over |
| Early stage in the development of plants and animals | embryo |
| The organ system that protects the body from damage, comprising of the skin,hair, scales, feathers, hooves and nails | integumentary system |
| A type of cell division that results in 2 daughter cells, each with half the chromosome number of the parent cell | meiosis |
| A type of cell division that results in 2 daughter cells each the same as the parent nucleus, typical of ordinary tissue growth | mitosis |
| The bodily system composed of skeletal, smooth,and cardiac muscle tissue and fuctins in movement of the body or of materials through the body | muscular system |
| Comprised of tissues, cells and organsthatregulate the body's response to internal and external stimuli or events | neurological system |
| A female reproductive cell that can divide to form an embryo usuallyonly after fertilization by a male cell | ova |
| Female reproductive part of a flower, consisting of an ovary, style and stigma | pistil |
| Produced by the combining of genetic material from more than one organism | recombinant |
| To generate offspring by sexual or asexual means | reproduce |
| The production of a new living organism by combining genetic information from tow individuals of opposite sex | sexual reproduction |
| The bodily system that consists of bones, their associated cartilage, and the joints. Supports and protects the body, produces blood cells and stores minerals | skeletal system |
| The reproductive cell of the male; male gamete | sperm |
| A minute,typically one-celled reproductive unit, capable of producing a new individual without sexual fusion | spore |
| Male reproductive part of a flower, typically consisting of a pollen-containing anther and a filament | stamen |
| Group of cells with a common structure and function | tissue |
| A difference or modification in structure, form or function in an organism deviating from other organisms of the same species or group | variation |
