LEVELS OF ORGANIZTION IN LIVING THINGS =NITROGEN, OXYGEN, ETC… ATOM COMPOUND ELEMENT O2= MOLECULE =H2O ORGANELLE =NUCLEUS, CELL MEMBRANE = BONE CELL, MUSCLE CELLBASIC UNIT OF LIFE= FIRST THING THAT IS LIVING CELL TISSUE =NERVE TISSUE, MUSCLE TISSUE =BRAIN, BICEP ORGAN ORGANSYSTEM =NERVOUS + MUSCLUAR SYSTEM =OAK TREE, HUMAN, WORM ORGANISM BACTERIA=

TYPES OF CELLREPRODUCTION MEIOSIS MITOSIS -PRODUCES 4 CELLS-NOT IDENTICAL TO PARENTCELL -1/2 # OF CHROMOSOMES-OCCURS IN SEXCELLS/GAMETES-OCCURS IN 2 STAGES(2 DIVISIONS) PROPHASE I & PROPHASE IIMETAPHASE I & METAPHSE IIANAPHASE I & ANAPHASE IITELOPHASE I & TELOPHASE II -PRODUCES 2 CELLS-IDENTICAL -SAME # OF CHROMOSOMESAS PARENT CELL-OCCURS IN BODY CELLS-OCCURS IN 1 STAGES(1 DIVISIONS) PROPHASE I METAPHASE I ANAPHASE I TELOPHASE I
