Living Environment Date Cell Unit Organelles & Life Functions Note Sheet The Cell Theory 1 2 3 Exceptions to the theory Relate the functions of the cell organelles to the Life Functions. CELL MEMBRANE CHLOROPLAST CYTOPLASM MITOCHONDRIA NUCLEUS RIBOSOME VACUOLE Living Environment Date KEY Cell Unit Organelles & Life Functions Note Sheet The Cell Theory 1 Cells are the basic unit of structure - all critters are made up of cells 2 Cells are the basic unit of function - all cells carry out the Life Functions 3 All cells come from preexisting cells Exceptions to the theory Viruses Mitochondria Chloroplasts Relate the functions of the cell organelles to the Life Functions. CELL MEMBRANE CHLOROPLAST CYTOPLASM MITOCHONDRIA NUCLEUS RIBOSOME VACUOLE Regulation controls what enters & leaves the cell - SIZE Excretion All wastes ext through the membrane Transport All materials are ABSORBED by the membrane Nutrition Ingestion of food Growth The membrane must increase in size Synthesis Photosynthesis Reproduction They have their own DNA make more of themselves Synthesis Make proteins at their ribosomes Synthesis Lots of molecules are made here Growth An increase of material will cause growth Transport Diffusion Respiration Site of Aerobic Respiration Synthesis Make proteins at their ribosomes Reproduction They have their own DNA make more of themselves Reproduction Mitosis originates here Synthesis Making of NEW chromosomes Regulation DNA controls all cell activities Synthesis Makes proteins Growth The addition of proteins leads to growth Excretion Stores wastes Nutrition Stores food Cyclosis
