Levels of BiologyMicro- = small•Biochemistry- atoms, bonds, molecules •Cell Biology-parts & function of cell•Genetics- heredity
Macro- = Large•Evolutionary theory•Ecology- organisms relating to one another•Botany- study of plants•Zoology- study of animals
Fields of Biology• Anatomy - The study of body parts and their
locations (ana = up, tom = to cut)• Physiology - The study of how various body parts
function (physio = nature)
• Botany - The study of plants (botan = grass, pasture)
• Cytology - The study of cells (cyto = cell)• Ecology - The study of the interrelations
between organisms and their environment (eco = house)
