BIOL 2050 1st Edition Lecture 9Outline of Last Lecture I. Proteins a. Typesb. StructureII. Nucleic Acidsa. Typesb. StructureOutline of Current LectureIII. Cell TheoryIV. MicroscopesV. Cellsa. Cell StructureCurrent LectureI. Cell Theory: a. Living things are made of cells b. All cells arise from preexisting cellsII. Microscopesa. Light Microscopesi. Brightfield1. Stained; you can see more of the cell2. Phase Contrast: changing how the light hits the cell3. Florescenceb. Electron MicroscopesIII. Cell Typesa. Prokaryotici. Structure1. Cell wall2. Nucleoid 3. NO membrane enclosed organelles4. Ribosomes b. Eukaryotici. Plant Cells, Animal Cells, Fungi cellsii. StructureThese notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.1. Nucleus: holds DNA, ribosomes are created inside, plasma membrane, nucleolus, transcription, nuclear pore2. Cytoplasm: matrix of the cell, contains all organelles, semi fluidmaterial.3. Plasma (Cell) Membrane: phosophilid bilayer, allows chemicalsand substances in and out of the cell.4. Ribosomes: translate mRNA into proteins, located on ER and free floating in the cytoplasm, made of RNA and proteins5. Endoplasmic Reticulum (ER): surrounds the nucleusa. Smooth ER: detoxifies, regulates calcium ions, creates lipidsb. Rough ER: creates proteins by attached ribosomes, protein folding, contains vesicles for transportation6. Golgi Body: ships and processes substances, series of folded membranes7. Vesicle: transports substances from one membrane organelle to another throughout the cell8. Cytoskeleton: provides structure in the cell, made of proteinsa. Microfiliments: thin tubes made of actinb. Intermediate fibers: only in animal cells, made of keratinc. Microtubules: hollow rods made from tubulin, used by organelles to move around.9. Cilia and Flagella: provides movement for the cell, cluster of microtubules and flagellen, cilia are shorter and more numerous.10. Lysosome: contains digestive enzymes, breaks down macromolecules and older cell parts11. Mitochondrion (Mitochondria): where cell respiration takes place, maternal DNA, uses oxygen to make ATP, double membrane12. Chloroplast: green from the chemical chlorophyll, takes sunlight and creates chemical energy, double membrane, only in plants13. Central Vacuole: Storage for plant cells, takes in water for growth14. Cell Wall: made of cellulose and gives plant cells their structure.15. Plasmodesmata: located in plant cell walls, cytoplamsic plasmas through cell walls that connect to other cell
