  1. CELL THEORY CELL SIZE 1. All living things are made of _____________.2. Cells are the basic unit of structure & function in an organism (= basic unit of __________)3. New cells are produced from _________________ cells Cells life existing PLANT ANIMAL BACTERIA ___________ cells > _________ cells > _____________

  2. phospholipids proteins CELL MEMBRANE (PLASMA MEMBRANE) Made mainly of ____________________ and _________________ HYDROPHOBIC “tails” of phospholipids make molecules line up as LIPID ________________ with POLAR heads facing _______ & NON-POLAR tails facing ________ out BILAYER in • MEMBRANE PROTEINS • ____________________- stick on inside or outside surface • ____________________- go part way or all the way through • _________________ - recognize “self” • _______________ PROTEINS- move molecules across membrane PERIPHERAL INTEGRAL GLYCOPROTEINS TRANSPORT FUNCTION: SELECTIVELY PERMEABLE Membranes are _________________________________ (=Semi-permeable) Allow certain molecules to pass through; but keep others out ___________ what enters & leaves cell Helps with _________________ CONTROLS HOMEOSTASIS cytoplasm __________________ = gel-like material + organelles between nucleus and cell membrane

  3. NUCLEUS NUCLEOLUS DOUBLE • Surrounded by ______________ MEMBRANE called the NUCLEAR __________________ • ___________ CENTER OF CELL • Nuclear ___________ allow molecules in & out • CONTAINS CELL’S GENETIC MATERIAL (_______) • Dark spot = NUCLEOLUS makes ___________________ (RNA) ENVELOPE CONTROL PORES DNA RIBOSOMES CHROMOSOMES DNA is scrunched up as ______________ in dividing cells. CHROMATIN DNA is spread out as ________________ in non-dividing cells.

  4. CYTOSKELETON Made of PROTEINS called ______________ & _________________ FUNCTION: _________________________ ___________________________________ MICROTUBULES MICROFILAMENTS Helps cell maintain shape; Support; Helps in movement

  5. CENTRIOLES MICROTUBULES Made of __________________________ Only seen in _______________ cells during cell division Function:__________________________________ ANIMAL Pull chromosomes apart;

  6. MITOCHONDRION (pl. MITOCHONDRIA) DOUBLE Surrounded by _____________ membrane Contains its own ___________ _______________ of cell Burns ____________ Stores energy released as ______ DNA Power plant GLUCOSE ATP CRISTAE Folded inner membrane = _________________ (increases surface area for more chemical reactions)

  7. RIBOSOMES FREE in cytoplasm ATTACHED Can be __________________ or __________ to Rough ER MADE OF ______________ & ________ FUNCTION: _____________________ PROTEINS RNA MAKE PROTEINS

  8. ENDOPLASMIC RETICULUM MEMBRANES Internal Network of ___________________ Rough ER: Attached ribosomes make _________________ which are modified and transported to Golgi for export Smooth ER: Makes membrane lipids (__________________) Regulates ________________ in muscles Breaks down _________________ in liver PROTEINS ROUGH ER SMOOTH ER (with ribosomes) (no ribosomes) STEROIDS CALCIUM TOXINS
