Document Summary
First to observe: single cell organisms (protists, bacteria, blood cells, muscle cells, sperm) Compound microscope: improved magnification and resolution, animal cells 20 micrometers, organelles 2micrometeres. Robert brown plant cells have a kernel" nucleus. Matthias schleiden all cells come from previous cells. Shwann structural similarities between plants and animals. Cell theory: all organisms consist of one or more cells, the cell is the basic unit of structure for all organisms, all cells arise only from pre existing cells. Unstained or stained: bright field/ phase contrast/ Have many processes that are highly conserved at the molecular level. Engage in many mechanical activities: transporting materials, assembly of structures, movement. Cell wall in addition to plasma membrane (except mycoplasma) Spherical cells, rod shaped cells, spiral cells. Protists very diverse groups, mostly single celled. Fungi single cells, and multi cellular, cell walls, heterotrophs. (cant make own food) Cytoplasm everything between plasma membrane and nuclear membrane.
