bacteria are a group of micro-organisms that replicates exponentially 2,4,8,16 etc. they are millionth of a meter), Low 02 environments bacteria get energy : Fermentation, Life began in water :Anaerobic bacteria: protects from UV
1303269838 | Cytoplasmic membrane | Boundary between the living cell and the environment | 0 | |
1303269839 | Cytoplasm | Fluid jelly substance biological reactions take place here | 1 | |
1303269840 | DNA | Hereditary material | 2 | |
1303269841 | Ribosomes | Translate genes into proteins | 3 | |
1303269842 | ATP | Universal energy currency | 4 | |
1303269843 | Prokaryotic cell | Small cell No nucleus DNA- circular (one) No organelles A unicellular organism | 5 | |
1303269844 | Eukaryotic vell | Large cell Nucleus DNA-Linear (several) Many organelles Does not have a cell wall Mainly multicellular organism (Human)/ Single-celled (Amoeba) | 6 | |
1303269845 | gram negative bacteria | a class of bacteria whose peptidoglycan layer of the cell wall is much thinner and therefore stains pink | 7 | |
1303269846 | gram positive bacteria | a class of bacteria whose cell wall layer is much thicker and resist penetration by stains , therefore satin purple | 8 | |
1303269847 | spiral bacteria | it is a spiral shaped aerobic organism. e.g spirochaete which causes syphilis and yaws | 9 | |
1303269848 | acid fast bacteria | a type of bacteria that stain with basic dyes and fluorochromes and resist decoloration by acid solutions. | 10 | |
1303269849 | cell wall deficient bacteria | a type of bacteria with no cell wall and therefore has many shapes. eg mycoplasm | 11 | |
1303269850 | cell wall | maintains the shape of a cell and also prevents it from bursting | 12 | |
1303269851 | cell membrane | sorrounds the cell and it is selectively permeable | 13 | |
1303269852 | cytoplasm | contains all the organelles of a cell | 14 | |
1303269853 | mesosome | gram positive, cellular respiration | 15 | |
1303269854 | peptidoglycan layer | both gram negative and positive, gives cell wall structural strength | 16 | |
1303269855 | capsule | both gram negative and positive, protects bacteria | 17 | |

1303269862 | outer membrane | gram negative, source of lipopolysaccharide | 24 | |
1303269863 | porin proteins | gram negative, acts as channels that are specific to different types of molecules | 25 | |
1303269864 | periplasmic space | gram negative, a space where enzymes and proteins help digest and move nutrients into cell | 26 |
