Document Summary

4. 1 microscopy: cell biology the study of individual cells and their interactions with each other, microscope magnification tool that enables researchers to study the structure and function of cells, micrograph an image taken with the aid of a microscope, resolution measure of the clarity of an image, magnification ratio between the size of an image produced by a microscope and its actual size, transmission electron microscope (tem) beam of electrons is transmitted through a biological sample. True nucleus where most of the dna is housed: extensive compartmentalization: have many membrane bound organelles that separate the cell into different regions, plant cells chloroplasts, central vacuole + cell wall, proteome the complete protein composition of a cell or organism, organelles and their functions, nucleus: genetic material is organized + expressed, nuclear pore: passageway for molecules into/out of nucleus, centrosome: where microtubules grow + centrioles are found, nuclear envelope: double membrane.
