- sexual reproduction
- a reproductive process that involves two parents that combine their genetic material to produce a new organism,which differs from both parents
- cell
- athe basic unit of structure and function in an organism
- asexual reproduction
- a reproductive process thst involves only one parant and produces offspring that are identical to the paraent
- pasteurization
- a process of heating food to a temperture that is high enough to kill most harmful bacteria without changing the taste of food
- parasite
- the organism that benefits by living on or in a host in a parasitism interraction
- cell wall
- a rigid layer that surounds the cell where the process of photosyntheis takes place
- symbiosis
- a cllose relationship between two organisms of different species that benefits at least one of the organisms
- host
- the organism that a parasite or virus livezin or on
- fungi
- a eukaryotic organism that has cell walls, uses spores to reproduce, and is heterotroph that feeds by absorbing its food
- binary fission
- a form of asexual reproduction in which one cell divides to form two identical cells
- mutualism
- a relationship between two species in which both species benefit
- bacteriophage
- a virus that infects bacteria
- bacteria
- single celled organisms that lack a nucleus: prokaryotes
- flagellum
- a long whiplike structure that helps a cell to move
- cilla
- The hairlike projections on the outside of cells that move in a wavelike manner
- contractile vacuole
- The cell structure that collects extra water from the cytoplasm and then expels it from the cell
- pseudopod
- a " false root" or temporary bulge of cytoplasm used for feeding and movement in some protozoans
- amaebas
- a group of protozoans that move by forming pseudopods
- cell membrane
- a thin layer that surrounds a cell
- virus
- a tiny, nonliving particle that enters and then reproduces inside a living cell
- aerobic respiration
- a pro cess in some living cells where oxygen is used to break down food into carbon dioxide and water and release energy for life activities
- bacilla
- rod-shaped bacteria
- antibodies
- substances that kill or inhibit the groth of bacteria
- spore
- a tint cell that is able to grow into a new organism
- anarobic repiration
- a process in some living cells where food is broken down to relese energy for life activities without using oxygen
