Cell TransportWarm Up:
1) List the three points of the cell theory from your homework last night.
2) Describe the difference between unicellular and multicellular organisms.
Homework: Complete the “practice” found on the last notebook page for today
Cell – the basic unit of all life
Semi-permeable – some objects can pass through cell membrane (mostly water)
Basic Cell Organelles: Cell Membrane – protects cell/gatekeeper Cytoplasm – fluid inside cell/ helps keep shape Nucleus – typically holds cells genetic material
Prokaryotic vs. Eukaryotic OrganismsProkaryotic – single-celled organisms, no nucleus - usually bacteria, not very complexEukaryotic – multi-cellular organisms, nucleus - usually more complex with more organelles
Movement Into and Out of Cells:Diffusion: movement from an area of high concentration to low concentration
Osmosis: diffusion of water across a semi-permeable membrane
Tuesday, January 15, 2013Wednesday, January 16, 2013
Using Energy to Transport Materials Across the Cell MembraneTwo Main Categories:
Passive Transport/Diffusion (usually small particles) – Moves substances from areas of high concentration to areas of low concentration
Example: Food coloring added to a beaker of water: before after
Active Transport (usually larger particles) – Relies on the cell using energy (ATP) to move particles across the membrane
Three Categories:1. Transport Proteins: Special proteins use energy/ATP to pump materials into cell (gatekeeper)2. Endocytosis: membrane surrounds particles to move them inside (see diagram on next slide)3. Exocytosis : release of substances from inside vesicles through joining and then releasing from the cell membrane (see diagram on next slide)
Exchanging materials between the cell and its environment
Passive Transport Active Transport
Diffusion
Osmosis
Transport Proteins use ATP
Endocytosis (reverse for Exocytosis)
Video’s and Examples
Passive and Active Transport AnimationsEndocytosis and Exocytosis Animation
Homework/PracticeDIRECTIONS- First Identify if the process is moving materials by active or passive transport. Then determine if the process is diffusion, osmosis, transport proteins, endocytosis, or exocytosis.
1. WATER MOVES OUT OF PLANT LEAF, CAUSING IT TO WILT AND DRY.
2. IF YOU PLACE A TEA BAG IN WATER AND TEA IS MADE.
3. IF FOOD THAT IS TOO LARGE TO ENTER THROUGH THE CELL MEMBRANE IS BROUGHT INTO THE CELL TO KEEP IT FROM DYING.
4. YOU SMELL THE DELICIOUS ODOR OF BAKING COOKIES BEFORE YOU ENTER THE KITCHEN.
5. FRESH WATER MOVES INTO A SINGLE CELLED ORGANISM.
6. A ONE CELLED AMEOBA SURROUNDS A PARTICLE OF FOOD.
7. EXCESS SALT THAT AN IGUANA HAS SOAKED UP IN THE OCEAN IS REMOVED THROUGH THE NOSTRILS.
8. IF A PLANT PUMPS MINERALS FROM THE SOIL TO THE ROOT OF THE PLANT.

Organelle Chart Organelle Scavenger Hunt - BYOT
Homework: Create chart of cell organelles and their functions Tell whether the part is in plant, animal, or both cells
Organelle: – parts of a cell with specific function – structure in the cytoplasm of eukaryotic cell that can act as a storage site, process energy, move materials, or manufacture substances

Cell Organelle Quiz and Cell Cycle NotesWarm Up:
Homework: Make a concept map with Cell in the middle and 4 spokes coming out titled: division, transport, animal and plant. List the vocabulary words we’ve done in class under the specific category they belong to.
Respiration and Photosynthesis: - reactions are complete opposites of each other
Respiration: C6H12O6 + 6O2 ATP + 6 H2O + 6 CO2
Photosynthesis: Sun + 6 H2O + 6 CO2 C6H12O6 + 6O2

Cell Organelle Quiz and Cell Cycle NotesWarm Up:
Homework:
Cell cycle - normal sequence of the development and division of a cell
Three main stages:1) Interphase - cell is performing normal
functions and preparing to divide
- the longest part of the cycle - cell grows about twice its original
size - goes about regular cell activities - DNA is copied to prepare for
mitosis2) Mitosis - nucleus splits and divides
- prokaryotes do not do this (no nucleus)- usually the shortest period in cycle- goal of mitosis is to transfer DNA and other cell structures from parent cell to new cell
3) Cytokinesis – occurs directly after mitosis - parent cell pinches off - two genetically identical cells form

Study for Cell Test and Finish Study Guide Food, Exercise, and Energy Projectcalorie - with a lowercase “c,” the term refers to the amount of energy needed to raise thetemperature of one gram of water one degree Celsius.Context: When it comes to staying healthy, counting calories is just one aspect. Calorie - with an uppercase “C,” the term refers to the amount of energy required to raise onekilogram of water (about 2.2 pounds) one degree Celsius; one Calorie, or kcal, is equal to 1,000calories.Context: Nutrition is measured in Calories. diet - everything that is consumed. A balanced diet is based on the principle that healthfulfoods and appropriate nutrients must be consumed each dayContext: Eating a healthful diet helps prevent high cholesterol, high blood pressure, heartdisease, and many other health problems. Food Guide Pyramid - a visual representation of the number of recommended daily servingsin each of the six food groups; designed by the U.S. Department of AgricultureContext: Use the Food Guide Pyramid as a general guideto help you choose a healthful diet. nutrients - substances, including proteins, carbohydrates, vitamins, and minerals, found infoods that are necessary for good healthContext: Teenagers need to consume a great deal of calcium, the nutrient that helps buildstrong bones and teeth.

Disease Examples
-Microbiology is the study of “very small” organisms-many not visible with the “unaided eye”
-many can cause disease and affect functions- explores bacteria, protists, some fungi, some parasites, and viruses
BacteriaCharacterisics• Simplest kind of life
known• Found everywhere• Prokaryotes (DNA not
stored in nucleus)
Reproduction• Binary fission
Bacteria3 main shapes• Spiral (also known as Spirillum) • Rod (Bacillus)• Round (Coccus)
E. Coli – Causes food poisoningStreptococcus –
causes strep throatMost spirilla affect animals
ProtistsCharacteristics• Usually single-celled• moist environment• Grouped by how they move and get food
Plant-like Protist called Volvox
Plant-like Euglena
Animal-like Protist called Paramecium
Animal-like Protist called Amoeba
ProtistsFlagellates
• Move with a whip like tail called flagella
• Euglena• Plant-like
Psudopodia• Move with false feet
called psudopods• Disease causer –
Ameoba causing Dysentery
Ciliates
•Move with tiny hairs called cilia•Cilia help capture food Paramecium feeding (animal-like)
FungiCharacteristics• 3 groups: mushrooms, molds, yeasts• Act as decomposers and absorbs nutrients
ReproductionMostly asexual Mostly with spore dispersal
FungiGood Examples• Food• Yeast is used to make bread• Penicillin kills bacteria
Disease Causing• Athlete’s Foot is a parasitic
fungal infection caused by
• causes scaling, flaking, and itch of affected areas
ParasitesCharacteristics• a harmful relationship to the host
Reproduction• depends on the parasite
ParasitesGood Examples
• Harmful by definition
Disease Causing
• Tapeworms - from uncooked meat
• Fleas• Bed bugs - suck
blood from sleeping victims
VIRUSESCharacteristics• Smaller than bacteria• NOT living organisms• Consist of genetic material within a special
protein coating called a capsid.
VIRUSESReproduction• Use host cell to copy DNA and produce new
viruses• 5 steps to virus multiplication:
1. Attachment2. Injection3. Production4. Assembly5. Release
VIRUSESHelpful Virus Examples Bad Examples
•West Nile virus • Influenza
• Used to transfer helpful genes into cells – gene therapy
