cells Flashcards

Nucleus:
Contains genetic info which controls the activities of the cell
Cytoplasm
This is where most of the cells reactions happen
Cell membrane
Controls what goes in and out of the cell
Mitochondria
This where reputation occurs and the cell gets its energy from here
Ribosomes
Protein synthesis occurs here
Cell wall
