Cell size is the same for whale and humming bird. Electron microscopes 1000x more powerful than light microscopes. There are trillions of cells in human body but 200 different types of cells according to structure and function. All muscle cells contain multiple nuclei (multinucleated), cytosol, ribosomes, and mitochondria which is common to many cells. Muscle cells slow-twitch (type 1) and fast twitch (type. Most cells have major 3 subdivisions such as (i) plasma membrane: which encloses the cell (ii) nucleus: which contains the cells genetic material (iii) cytoplasm: the portion of the cell"s interior not occupied by the nucleus. Plasma membrane: thin membraneous structure which encloses the cell. Oily and separates icf(interior cellular fluid) from ecf ( extra-cellular fluid)
