9/7/10-Pick up your book & take out your magic square wkst from Friday to be checked. Do-Now: Create flashcards for the 16 terms listed on p. 182 of your book. Put the word on one side and the definition on the other. Any extra time should be spent STUDYING for your quiz (chemistry and macromolecules).
Do-Now: What does passive transport mean? List two examples of passive transport from the reading assignment.
8/23/11-Pick up your book & set out your homework to be checked. Any extra time should be spent STUYDING for your cell test today!!!! Do-Now: 1.List the characteristics of living things. 2.Contrast prokaryotes & eukaryotes. 3.The organelle responsible for making proteins is the ____. 4.The organelle that transports materials for a cell is the____. Warm up, egg observations, review sheet, test, vocab
8/24/11-Get your book & pick up the word puzzle. COPY & ANSWER the following questions on a BLANK SHEET of paper. 1.How do you think you did on the cell test? 2.Honestly, how long did you study? 3.Have you seen Mrs. C or Mrs. L for help? 4.What could YOU do to improve your grade? 5.What could WE do to help you? Complete the Transport Word Search quietly when you are done. You will be turning this in.
1/30/12- Pick up the Handout at the back for you and your row. Place on each persons desk. Please & Thank you. !! Get your Osmosis Lab out from Friday. If you were not here. Look in the Missed Assignment Tray for your class.
1/30/12- Define the following terms on a clean sheet of Paper. Title: Cellular Transport 1.Passive Transport-transport that does not require the use of energy 2.Diffusion 3.Osmosis 4.Facilitated Diffusion 5.Isotonic 6.Hypotonic 7.Hypertonic
Cellular Transport Essential Questions: How does fertilizer affect the growth or death of plants? How would changing the environment of a fish from fresh to salt water affect its survival rate? Why is it so important to have the proper concentration of an IV drip while you are in the hospital?
In your notes section: Define SOLUTE and SOLVENT. Highlight these definitions. They are VERY important!
Cell Transport 1.Passive transport - particles move into and out of a cell without using any energy from the cell. *Think of going down a slide…
A. Diffusion - movement from areas of high concentration to lower concentration.
B. Osmosis - diffusion of water across a membrane (1) isotonic - when concentration is equal on both sides of membrane
(2) hypotonic - when the salt or solute concentration is low outside of cell. The water will move into the cell. The cell will swell. Animals cells can burst (cytolysis). Some animals have contractile vacuoles to remove excess water. Plant cells will be rigid (turgor)
(3) hypertonic - when solute concentration is greater outside of the cell. The water will be pulled out of the cell. The animal cell will shrivel up (crenated). normal red blood cellcrenated red blood cell
A plant cell cytoplasm will shrivel up away from the cell wall (plasmolysis) normal elodea cellplasmolysis
C. Facilitated Diffusion -the transport of specific particles through a membrane by a carrier protein
ION CHANNELS Protein channels that only certain ions can pass through, such as sodium, potassium, calcium, and chloride. Does not require energy
1/31/12 Take out & Work on the Crossword from yesterday…& your Osmosis Lab Take out your 7 Vocabulary Words for cell transport. Take out your osmotic solutions wkst. There will be 7 questions posted on the next slide. Answer them in your do-now section using COMPLETE SENTENCES.
Answer the following questions using complete sentences. 1.Define passive transport. 2.List the 4 types of passive transport we discussed. 3.The movement of substances from areas of high concentrations to low concentrations is ____. List 2 examples of this. 4.The diffusion of water across a membrane is ____. 5.Using carrier proteins to transport particles through a membrane is ____ 6.If you put a cell into a hypotonic solution, what will happen? 7.If you put a cell into a hypertonic solution, what will happen?
Ticket to Leave Draw pictures to depict hypertonic, hypotonic, and isotonic.
1/31/12-Take out your Osmotic Wksheet, & your 7 vocabulary words over Cell Transport Do-Now: 1. What is passive transport? 2. Does passive transport require additional energy from the cell? 3. Passive transport moves substances from ____ concentrations to _____ concentrations. 4. Define active transport.
Define the following terms; add to your Cell Transport Vocab: 1.Active Transport 2.Endocytosis 3.Exocytosis 4.Phagocytosis 5.Pinocytosis
2. Active Transport - using energy to transport a particle through a membrane against a concentration gradient *Think of climbing up a slide…
A. Carrier proteins - they bond and drag molecules across to the other side
B. Sodium-Potassium Pump - The most important energy using process in your body. (1/3 of all the energy) For every 3 sodium ions (Na + ) pumped out, two potassium ions(K + ) are pumped in.
C. Coupled channels -pulls food molecules (glucose) into the cell with the sodium ion
Ticket to Leave Draw pictures to depict hypertonic, hypotonic, and isotonic.
2/1/12 -Take out Egg Lab, HW, Crossword Do-Now: 1.Why is it dangerous for humans to drink ocean water? 2.True or False? If a cell is in an isotonic solution, the molecules do not move. 3.The shrinking of plant cells is ___. This happens in a ___ solution. 4.The shrinking of animal cells is ___. This happens in a ____ solution.
D. Endocytosis - engulfing the particles too large to pass through the membrane
1. pinocytosis (cell drinking) - taking in drops of liquid containing large molecules
2. phagocytosis (cell eating) - taking of other cells, cell fragments or large organic particles into the cell
E. Exocytosis - dumping of wastes, or excretions or secretions across the cell membrane
2/2/12-Pick up your book & set out your review sheet answers. Do-Now: Complete the crossword puzzle on transport. (If you turned in your word find like you should have, it is on your desk.) Any extra time should be spent STUDYING for your test.
Recall the structure of the Cell Membrane… 1.The cell membrane is a double layer. 2. It is composed of phospho- lipids and proteins. 3.The structure of a phospholipid Head Tail
4.The phospholipids are arranged with the heads out and the tails in. Protein Hydrophobic Tails Hydrophilic Heads
5.Proteins are in the double layer and serve several different functions. a) Transport proteins –involved in diffusion and transport (1) channel proteins (2) carrier proteins b) Marker proteins – identify the cell c) Receptor proteins -involved in cell communication
