| Question | Answer |
|---|---|
| Classification | Grouping of organisms or objects based on a set of criteria that helps organize, communicate, and retain information. |
| Taxonomy | Branch of biology that identifies, names, and classifies species based on their natural relationship. |
| Phylogeny | evolutionary history of species. |
| Binary Fission | asexual form of reproduction used by some prokaryotes in which a cell divides into tow genetically identical cells. |
| Conjugation | form of reproduction used by some prokaryotes in which the prokaryotic cell attach to each other and exchange genetic material. |
| Lytic Cycle | viral replication process in which genetic material ofthe virus enters the host cell's cytopolasm, the cell replicates the viral DNA or RNA and the host cell is instructed for manufacture capsids and assemble new viral particles which then leaves the cell |
| Lysogenic Cycle | viral replication process in which viral DNA inserts into the host cell's chromosome, may remain dormant and later activate and instruct the host cell to produce more virus. |
| Retrovirus | RNA virus, such as HIV, with reverse transcriptase in its core. |
| Protozoan | Heterotrophic, unicellular, animal0like protist |
| Alternation of Generation | Reproductive life cycle that alternates between a diploid(2n) sorophyte generation and a haploid(n) gametophyte generationi |
| Chitin | tough, flexible polysaccharide in the exoskeletons of insects and crustaceans and in fungal cell wallls. |
| Hypha | Threadlike filament that makes up the basic structural unit of a multicellular fungus. |
| Mycelium | complex, netlike mass made up of branching hypae |
| Spore | Fern structure formed by clusters of sporangia, usually on the undersides of a frond. |
| Vascular Tissue | specialized tissue that transports water, food, and other substances in vascular plants and can also provide structure and support. |
| Cotyledons | seed structure that stores food or helps absorb food for the sporophyte of vascular seed plants |
| Stomata | openings in the outer cell layer of leaf surface and some stems that allow the exchange of water, carbon dioxide, oxygen, and other gasses between a plant and its environment. |
| Tropisms | response to an external stimulus in a specific direction. |
| Guard Cell | One of a pair of cells that function in the opening and closing of a plant[s stomata by changes in their shape. |
| Transpiration | process in which water evaporates from the inside of leaves to the outside through stomata. |
