From Bacteria to Plants Chapter 2, Section 2 (48-57) Bacteria Define bacteria. Bacteria are single-celled prokaryotes. Some are autotrophs and some are heterotrophs. Describe the cytoplasm. The cytoplasm is the gel-like material inside the cell membrane. What is the function of the ribosomes? The ribosomes produce proteins. Define flagellum. The flagellum is a whip-like structure that helps the cell move. Name the 3 basic shapes of bacteria. Shapes of bacteria: 1. spiral 2. rod-like 3. spherical Define respiration. Respiration is the process of breaking down food to release its energy. Name some of the good things bacteria do. Bacteria: • produce oxygen • are used in food production (ex/ yogurt, cheese, pickled veggies) • are decomposers • are useful in environmental cleanup • are involved in health maintenance • are used in medicine production (ex/ insulin for those with diabetes)
