3.1 Diversity of Organisms and extended study Term Definition Pathogen Antibiotic Disease causing organism Substances produced by bacteria or fungi [accept microorganisms] to treat infections[kill other bacteria or fungi] Saprophytic Parasitic Asepsis Feeds on dead organisms An organism living in or on another organism causing it harm. Sterility Autotrophic [bacteria] Heterotrophic [oragnism] Methods used to prevent unwanted micro-organisms entering an area [of an experiment] Free from all organisms [Bacteria] capable of producing own food [organism] not capable of producing their own food i.e organism obtains food from other organisms Photosynthetic [bacteria] Using light to make food or obtain energy Chemosynthetic[bacteria] Make food or obtain energy using a chemical reaction Prokaryotic [bacteria] [Bacteria] which do not possess a nucleus or other membrane bound organelles. Batch Flow Food Fixed amount of nutrients added at beginning of production or Processing (bioreactor) emptied at end of production or where organisms are in a 5 phase growth curve These definitions are the work of practising teachers - not the SEC - and may have to be adjusted depending on the precise wording of an exam question. 3.1 Diversity of Organisms and extended study Complete the definition for each term Term Definition Pathogen Antibiotic Saprophytic Parasitic Asepsis Sterility Autotrophic [bacteria] Heterotrophic [bacteria] Photosynthetic [bacteria] Chemosynthetic[bacteria] Prokaryotic [bacteria] Batch Flow Food Processing These definitions are the work of practising teachers - not the SEC - and may have to be adjusted depending on the precise wording of an exam question. 3.1 Diversity of Organisms and extended study A definition is provided. Write in the correct term Term Definition Disease causing organism Substances produced by bacteria or fungi [accept microorganisms] to treat infections[kill other bacteria or fungi] Lives on dead organisms An organism living in or on another organism causing it harm. Methods used to prevent unwanted micro-organisms entering an area [of an experiment] Free from all organisms [Bacteria] capable of producing own food [organism] not capable of producing their own food i.e organism obtains food from other organisms Using light to make food or obtain energy Make food or obtain energy using a chemical reaction [Bacteria] which do not possess a nucleus or other membrane bound organelles.
