Document Summary
All cells have 3 things in common: membrane, cytoplasm, & dna (genetic material). Cell membrane: which separates the cell from its environment. Separates the cytoplasm of the cell from its environment. Protects the cell & controls what enters and leaves. Cell membranes are selectively permeable only allowing certain materials to enter or leave. Composed of a lipid bilayer made of phospholipid molecules. Dna: cells genetic material, found within in the nucleus of. Cells maintain their shape through cytoskeleton, which includes micro-filaments (which are made of protein) & micro-tubules which are thin hollow tubes. All living things are made of one or more cells. Cells are the basic unit of structure & function in organisms. Cells come only from the reproduction of existing cells. Cells differ in size, shape, and function. The female egg cell is the largest cell in the body & can be seen without a microscope. Plant & animal cells with a nucleus & membrane-enclosed organelles.
