– specialized type of nuclear division that only occurs in reproductive organs – yields 4 daughter cells that differ genetically from the mother nucleus Stages of mitosis and what happens in each; be able to identify a picture Interphase – normal metabolic activities, growing, DNA reproduction Prophase – Microtubules array asters (stars) and are seen extending from the centrosome matrix around the centrioles. Nuclear envelope dissolves and fragments remain in center (look for asters) Metaphase – chromosomes line up (look for meeting up) Anaphase – chromosomes separated (look for pulling apart) Telophase – chromosomes at different ends (look for cleavage furrow)
Know the parts of the plasma membrane and be able to draw a diagram Organelles – know function of major organelles Centriole – spindle-apparatus for moving DNA Lysosome – cell’s digestive system Peroxisome - Ribosome – protein synthesis Mitochondria – produces ATP Golgi apparatus – packaging, processing of proteins Smooth endoplasmic reticulum – (no ribosomes) synthesize lipids and proteins Rough endoplasmic reticulum – (with ribosomes) packaging of proteins Epithelial tissue
