CELL STRUCTURES Unique to plants? Cells Alive link
CELL PROCESSES- HOMEOSTASIS Balance!
CELL PROCESSES- PERMEABILITY Homeostasis! Cells absorb and excrete materials to maintain a constant balance
CELL PROCESS- ENERGY CONVERSION THE Energy currency of the Cell IS ATP!
CELL PROCESS- ENERGY CONVERSION Photosynthesis
CELL PROCESS- MEMBRANE TRANSPORT Passive transport Diffusion Facilitated diffusion Active transport
CELL PROCESS- TRANSPORT BY OSMOSIS The movement of water thru a semipermeable membrane until EQUILIBRIUM is reached Hypotonic solution Hypertonic solution Equilibrium Less solute More solute Semipermeable membrane
CELL PROCESS- SYNTHESIS OF NEW MOLECULES
VIRUSES NOT ALIVE! Needs host to reproduce Bacteriophage HIV
VIRUS VS. CELL Virus Outer Covering Genetic Material Organelles Reproduction Eukaryotic Cell Protein capsid (some w/envelope) Cell membrane + cell wall in some DNA or RNA (ds or ss) DNA (ds) Nope Yes - membranebound Must have host Multiply on own
VIRAL REPRODUCTION Lytic Cycle Lysogenic Cycle
CELL CYCLE Cytokinesis Animation M G 2 G 1 S Video
Role is“genetic DNA blueprint” for producing RNA Double stranded A with T G with C Nucleotide is composed of Deoxyribose sugar Phosphate Group Nitrogen Base
Role is“genetic RNA blueprint” for producing proteins Single stranded A with U G with C Nucleotide is composed of Ribose sugar Phosphate Group Nitrogen Base
REPLICATION ________
Prophase Metaphase MITOSIS Anaphase Telophase
MITOSIS T= two cells T= total chromosomes Video link

STRUCTURES & FUNCTIONSCARBOHYDRATES Glucose (building block / monomer) Polymer Function = energy, structure
STRUCTURES & FUNCTIONS - PROTEINS Building block of protein Polymer Function = energy, structure, catalysts
STRUCTURES & FUNCTIONS- FATS Fatty Acids Polymer (w/glycerol) Function = structure of cell membrane, cushion & insulates, & energy storage
STRUCTURES & FUNCTIONS- NUCLEIC ACIDS Nucleotide – the building block RNA DNA & RNA are the Polymers Function = genetic code DNA
