CELL STRUCTURES AND FUNCTIONS Annotate your diagram with the structures marked with a  according to the information on these slides Use a different color for the information on each slide. Add a color key to the diagram

Chromatin  is the form of DNA in the nucleoplasm; during cell division, it is coiled into chromosomes The NUCLEUS  houses the cell DNA, genes of which produce mRNA and tRNA for the process of protein synthesis DIRECTING THE CELL The NUCLEOLUS  produces the subunits of ribosomes  (rRNA) which are used to assemble amino acid chains Nuclear pores  permit RNA and proteins to cross the double membrane of the nuclear envelope 

MANUFACTURE, TRANSPORT, SECRETE Endomembrane system of channels and sacs ENDOPLASMIC RETICULUM  rough w/ribosomes produces proteins/glycoprotiens smooth – produces lipids GOLGI COMPLEX  modifies, sorts, packages products VESSICLES  transport between structures of the system

ENERGY MITOCHONDRIA  are the site of aerobic respiration. Organics -> ATP CHLOROPLASTS are the site of photosynthesis. Sunlight -> organics

STORAGE VACUOLES  store water, food and wastes (not cell products) Contractile V = bails out fw protists LYSOSOMES  and PERIOXISOMES  store enzymes for digestion and metabolism, respectively Central V = keeps plant cells full

cytoplasm network of protein microtubules and filaments CELL FRAMEWORK cytoplasm network of protein microtubules and filaments Coordinate the movement of organelles, of chromosomes during cell division Centrosomes, Centrioles, Spindle MOVEMENT Hair-like fibers that whip or paddle to move cells, trap & move particulates in nose, etc Cilia , Flagella 
