Study Guide: Cell Organelle’s, Passive/Active Transport, and Photosynthesis/ Cellular Respiration Test Date: Wednesday October 7, 2015 SB1A: Explain the role of cell organelles for both prokaryotic and eukaryotic cells, including the cell membrane, in maintaining homeostasis and cell reproduction. Organelle Description Function Animal, Plant or Both CELL WALL Rigid, tough, made of cellulose Protects and supports the cell Plant CELL MEMBRANE Thin, covering, protects cells Protects the cell, performs active transport and passive transport, moves materials in and out of the cell, communication Both CYTOPLASM Jelly like substance that contains organelles Pads and supports organelles inside the cell. Moves by cyclosis Both NUCLEUS Dense, ball shaped structure, contains DNA Controls all of the cell’s activities Both NUCLEAR MEMBRANE Thin covering over the nucleus Covers and protects the nucleus Both NUCLELOUS Small dark area in the nucleus Produces ribosome’s Both CHROMATIN In the nucleus, made of DNA and protein, contains genes Provides instructions for the cells activities, (growth, reproduction) Both ENDOPLASMIC RETICULUM Clear, tubular system of tunnels throughout the cell Transports materials like proteins around the cell Both RIBOSOME Small specks made of RNA. Found in cytoplasm or on the endoplasmic reticulum Makes proteins Both MITOCHONDRIA Location in the cytoplasm, bean shaped Supplies energy or ATP for the cell through cell respiration using glucose and oxygen Both VACUOLE Large open storage area, smaller in animal cells Storage tank for food, water, wastes or enzymes Both CHLOROPLAST Green structures that contain chlorophyll Captures sunlight and uses it to produce food through photosynthesis Plant GOLGI BODY Small bags with tubes connecting them Packages and secrets proteins for use in and out of the cell Both LYOSOME Small, round structures, containing enzymes Digests older cell parts, food or other objects Animal CENTRIOLE Small cylindrical Used with the spindle apparatus during mitosis Animal SB1D: Explain the impact of water on life processes (i.e., osmosis, diffusion). Describe diffusion: Moves things into/out of the cell (circle one or both!) Moves from high-to-low/low-to-high concentration(circle one) For large/small molecules (circle one or both!) Uses/does not use protein doorway (circle one) FACILITATED DIFFUSION IS LARGER AND USED PROTEIN DOORWAY Describe osmosis: Moves things into/out of the cell (circle one or both!) Moves from high-to-low/low-to-high concentration (circle one) For large/small molecules (circle one or both!) Uses/does not use protein doorway (circle one) Must be water and a semipermeable membrane Describe passive transport: Moves things into/out of the cell (circle one or both!)Moves from high-to-low/low-to-high concentration (circle one) For large/small molecules (circle one or both!) Uses/does not use protein doorway (circle one) Describe active transport: Moves things into/out of the cell (circle one or both!) Moves from high-to-low/low-to-high concentration (circle one) For large/small molecules (circle one or both!) Uses/does not use protein doorway (circle one) Protein does move larger molecules and used carrier protein Describe endocytosis: Example of active/passive (circle one) Moves things into/out of the cell (circle one or both!) For very large/small molecules (circle one or both!) Pinoocytosis – liquids Phagocytosis - solids Describe exocytosis: Example of active/passive (circle one) Moves things into/out of the cell (circle one or both!) For very large/small molecules (circle one or both!) Osmosis (Tonicity): Explain Hypotonic, Hypertonic, and Isotonic. Complete each diagram below. Use arrows to show osmosis. Label each cell and solution as hypertonic, hypotonic, and isotonic. 20 % solute 80 % solute 80 % solute 20 % solute 50 % solute 50 % solute _80__ % solvent __20_ % solvent _20__ % solvent _80__ % solvent _50__ % solvent _50__ % solvent Hypertonic – cell shrinks Hypotonic - cell swells Isotonic – cell has no change SB3A: Explain the cycling of energy through the processes of photosynthesis and respiration. What is pyruvic acid changed into? Organism: Alcoholic Fermentation Lactic Acid Fermentation ETHYL ALCOHOL YEAST & BACTERIA LACTIC ACID ANIMALS/HUMANS Stages of Photosynthesis Starting Molecule(s) Product(s) LIGHT & H2O LIGHT SPLITS H2O KEEPING THE HYRDOGENS HYDROGENS + CO2 LIGHT DEPENDENT REACTION LIGHT INDEPENDENT REACTION Stages of Respiration Starting Molecules O2 IS RELEASED & THE HYDROGENS ARE TAKEN TO THE NEXT STEP C6H12O6 Products Glycolysis glucose Pyruvate acid and ATP (2) Kreb Cycle Pyruvate acid and ATP 6 CO2 , 2 ATP, 2 FADH, 8 NADPH Electron Transport Chain Glucose 34 ATP, CO2 , H2 O Compare and discuss how cells store energy and release energy using ATP. Be specific! You may draw the cycle. ATP IS THE ENERGY STORING MOLECULE. THE ENERGY IS STORED IN THE BONDS OF THE 2ND & 3RD PHOSPHATE. WHEN THE BOND IN BROKEN BETWEEN THE 2ND & 3RD PHOSPHATE ENERGY IS RELEASED. ATP IS NOW ADP. T O GET BACK TO ATP ALL THAT HAS TO HAPPEN IS THAT A PHOSPHATE IS BONDED TO THE 2ND PHOSPHATE ON ADP Explain how the equations for photosynthesis and cellular respiration compare. THEY ARE BASICALLY THE SAME FORMULA BUT MIRROR IMAGES OF EACH OTHER. WHAT GOES INTO ONE PROCESS IS WHAT COMES OUT OF THE OTHER. WATER & CARBON DIOXIDE GO INTO PHOTOSYNTHESIS AND WATER AND CARBON DIOXIDE COME OUT OF CELLULAR RESPIRATION. What is the general chemical equation of photosynthesis and cellular respiration?
