|
|
The ability of an organism to react to its environment/other organisms is important because |
assures survival of organism: -allows organism to do biological activities ex. move toward nutrient rich areas, chimiotaxie (towards a chemical), phototaxie (towards light) |
|
|
Metabolism |
-absorption+transformation of chemical compounds (anabolisme, catabolisme) -obtain, generate, + use energy -elimination of waste |
|
|
Internal Equilibrium |
-pH, solute concentrations, temperature, osmotic pressure, etc. |
|
|
Organisms try and keep a ________ internal environment |
constant |
|
|
Reproduction |
-capacity to generate another organism Binary fission (asexual) Multicellular organisms: usually result in the union of two cells of different individuals |
|
|
Genetic Code |
-instructions for organisation + development -genome (a complete set of genes): decryption (transcription = transduction), generation of cellular machinery+new cells,+ cell maintenance |
|
|
Evolution |
-acquire transmissible changes that allow organism to respond better to its environment -selective pressures control whether or not adaptive changes are kept (ex. antibiotic resistance) |
|
|
Cellular Organisms |
-Fungi (Levure), Protistes (Algues), Bacteria, Archea (Methanogenes) |
|
|
methanogenes |
-archaebacteria, live in anaerobic environments, produce methane form a limited number of substrates |
