Are Viruses Alive?/Characteristics of LifeWarm Up:
1.Draw a food web OR food chain that involves at least 4 organisms.
CHOOSE ONE to draw and discuss.
Homework: Read Section 1.1 of Unit E in textbook. Define the four vocabulary words and answer questions 1-5 on page 15E.

Record your decision after reading the “Are Viruses Alive” article. Make your decision whether you think they are alive or not, then support your claim with evidence from the text!
After you’ve completed the above task, open your text book to section 1.1 of Unit E and list the characteristics something must have to be considered living below.
After reviewing this, does it change your mind about a virus? Why or why not?

Characteristics of Living Things Review•Organized
•Use energy for chemical processes –
•Respond to stimuli
•Grow, develop, adapt
•Reproduce / contain genetic material
•All living things are made of cells.
Unicellular Multicellular

Unicellular vs. Multicellular •Made of one single cell•Found mostly in or near water•Mainly bacteria•Called “Prokaryotes”•Can reproduce without the aid of another organism (Asexual)
•Split apart and copy
•Made of many (with different jobs)•more complex•Different parts of organism have different functions (roots vs. leaves) (heart vs. stomach)
•Called “Eukaryotes”•Need another individual to reproduce (Sexual)
Cell Theory
1. Every living thing is made up of at least one cell
2. Cells create structure and functions of life
3. Cells only come from other cells

Cell Cycle
Warm Up:
Sir Issac Newton once said, “If I have seen further, it is because I was standing on the shoulders of giants. Based on what you have learned, what is your interpretation of that statement. 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

Warm Up:
Identify following parts of the cell cycle: Interphase, Prophase, Metaphase, Anaphase, Telophase.
What happens during cytokinesis?????
Homework: Read section 2.3E (pg. 56 – 63E) and answer questions 1-6.
•Exchange of materials between a cell and the environment•Water is necessary for transport of most materials.•The cell membrane is semi-permeable – some things can pass across. Passive Transport (usually small particles)Relies on concentration of substances and thermal energy (think of dye spreading in a beaker of water)Two main categories:1. Diffusion: movement from an area of high concentration to low concentration2. Osmosis: diffusion of water across a semi-permeable membraneActive Transport (usually large particles)Relies on the cell providing energy supply (ATP)Three Categories:1. Transport Proteins: Special proteins use ATP to pump materials into cell2. Endocytosis: membrane surrounds particles to move them inside3. Exocytosis : release of substances from inside vesicles through joining and then releasing from the cell membrane

Passive and Active Transport AnimationsEndocytosis and Exocytosis Animation
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.
