THE NUCLEUS, BECAUSE FIRST OF THE NUCLEUS CONTROLS MOST OF THE HEREDITARY INFORMATION OF DNA YOU KNOW WHAT IS RIGHT? (DEOXYRIBONUCLEIC ACID) WHICH IS FOUND ON THE CHROMOSOMES. ALL THE OTHER ORGANELLES THAT DOES THERE OWN FUNCTIONS ARE CONTROLLED BY THE NUCLEUS. FOR EXAMPLE:
NUCLEUS: HEY RIBOSOMES!!
RIBOSOMES: YEA BOSS?
NUCLEUS: GO TO THE ENDOPLASMIC RECTULUM AND PRODUCE PROTEINS THERE
RIBOSOMES: YOU GOT IT BOSS!
SEE.... RIBOSOMES PRODUCE PROTEINS FOLLOWING CODED INSTRUCTIONS THAT COME FROM THE NUCLEUS. "THE CONTROL CENTER"
