ANIMAL DEVELOPMENT

ANIMAL DEVELOPMENT WHAT IS THE TERM FOR THE FUSION OF GAMETES? FERTILIZATION IS AN EGG CELL STILL JUST AN EGG CELL WHEN A SPERM HAS FERTILIZED IT? FERTILIZED EGG = EMBRYO

ANIMAL DEVELOPMENT HOW DOES THAT SINGLE CELLED EMBRYO, TURN INTO A MULTI-CELLULAR ANIMAL? YOU NEED TO GO FROM ONE CELL TO MANY CELLS, WHICH MEANS YOU NEED CELL DIVISION…

ANIMAL DEVELOPMENT CLEAVAGE A FORM OF MITOTIC CELL DIVISION RAPID MITOSIS, WHICH DOESN’T GIVE THE CELL TIME TO REGROW ADVANCED TERMS MORULATION BLASTULATION GASTRULATION

ANIMAL DEVELOPMENT DIFFERENTIATION IF CLEAVAGE USES MITOSIS, AND MITOSIS MAKES “IDENTICAL” OFFSPRING, HOW CAN MULTI-CELLULAR ORGANISMS HAVE CELLS THAT ARE SO DIFFERENT? (I.E. NERVE CELLS, STOMACH CELLS, SKIN CELLS, ETC.) DIFFERENTIATION THE PROCESS BY WHICH CELLS BECOME SPECIALIZED

ANIMAL DEVELOPMENT DIFFERENT CELLS, USE DIFFERENT PARTS OF THE DNA DIFFERENTIATION EVEN THOUGH EVERY CELL IS GENETICALLY IDENTICAL, NOT EVERY CELL USES THE SAME DNA… DIFFERENT CELLS, USE DIFFERENT PARTS OF THE DNA

ANIMAL DEVELOPMENT THE PROCESS OF GOING FROM A SINGLE FERTILIZED EGG TO A MULTI-CELLULAR ORGANISM IS REFERRED TO AS DEVELOPMENT DEVELOPMENT CAN OCCUR EXTERNALLY OR INTERNALLY

ANIMAL DEVELOPMENT LET’S FOCUS ON HUMANS!! HUMAN REPRODUCTION NEXT
