lysosomes                                               nucleus
           cell organelles that                                    contains the genetic material
           contain chemicals                                       (DNA) and serves as
           (enzymes) to                                            the control center
           break down food                                         of the cell
           and recycle waste
           materials





           mitochondrion                                           organelle
           a rod-like organelle                                    a structure
           that produces most of                                   within a cell
           the energy that is used                                 that carries
           by a cell                                               out a specific
                                                                   function





           nuclear envelope                                        ribosomes
           a membrane that encloses                                the organelles that
           the cell’s nucleus;                                     produce proteins
           separates the                                           needed by the cell
           chromosomes from
           the rest of the cell






           nuclear pores                                           tissue

           tiny openings that                                      a group of similar cells
           allow materials to                                      that perform the same
           pass in and out of                                      function
           the nucleus








           nucleolus                                               vacuole
           a organelle that                                        sacs that contain
           produces ribosomes                                      water and store
                                                                   nutrients and
                                                                   waste products
