theory that eucaryotes evolved when a procayote captured other bacteria by phagosytosis--> bacteria resisted being digested and its genes became incorporated in the host's DNA
*bacteria -do not have ribosomes
-no organelles -"before nucleus"
-DNA is circular and linear & only 1 chromosome
-most organisms -DNA inside double helix
-multiple organelle -multiple chromosomes
-true nucleus -"having a true nucleus"
The process by which living organisms produce larger molecules from smaller ones
cell--> tissue--> organ--> organ system--> organism
