window pane terms #5
1.Chloroplast- organelle found only in plant cells, it makes chemical energy (sugar/ glucose) using solar energy (sunlight), water and carbon dioxide.
2.Mitochondrion (singular) - responsible for breaking down sugar (glucose from plants) into a more usable form (ATP) for our cells. Found in animal cells and plant cells. Cells that do more work have more mitochondria in their cells (muscle cells and sperm cells have the most!).
3.Centrioles- organelles found only in animal cells that are only active during cell division (mitosis) where their job is to make sure that duplicated DNA strands get pulled apart evenly.
4.Ribosomes- found in plant and animal cells, they are responsible for building proteins and enzymes in a cell by using instructions they receive from the DNA via an RNA strand.
5.Nucleus- the control center for the cell, it contains the DNA instructions used to make every part of your body, your DNA NEVER,NEVER, NEVER leaves the nucleus!!
6.Cell wall- found only in plants, it provides structure and support to plant cells.
7.Cell or plasma membrane- found in plant and animal cells, it controls the movement of all substances in and out of the cell. SUPER IMPORTANT!
8.Cytoplasm- gel-like substance that all of the organelles are suspended in, it provides a medium for nutrient exchange as well as a cushion for the organelles.
9.Bioenergetic reactions- Chemical reactions in a cell that involve the creation of energy from sunlight or the break down of sugar for usable forms of energy: ex.- aerobic respiration (breathing), anaerobic respiration (fermentation), and photosynthesis.
10.Activation energy- the least amount of energy required to start any chemical reaction. (You have to start cellular respiration with 2 pieces of ATP in order to carry out the reaction and obtain 36 pieces of ATP)

transport videos
transport across a cell membrane interactive
Go here to see how cell transport works and get some visuals for your window pane terms!http://www.wiley.com/legacy/college/boyer/0470003790/animations/membrane_transport/membrane_transport.htm
check out a blood cell in various solutions
Click on the link below to see how your red blood cells respond to hyper-, hypo-, and isotonic solutions:scroll down to Biology 12 and then click on the rectangle that says "red blood cells" in it(while you are there check out all of the other types of transport as well!)http://www.coolschool.ca/content/showcase.php?type=science
After organic compounds and cell transport will begin the cell itself and we'll use an old friend to help us along:
Greatest Discoveries with Bill Nye: Biology--Friday after your test!
Window panes
Your 4th set of Window panes won't be due until Wednesday! You get an extra Day. Why?
Because for the rest of the semester your window panes will be handled like a project. If you have been doing them correctly, you know how long it takes and will agree that they deserve to have more weight than a homework grade. I've decided that I will add them all together at the end of each grading period( not including the ones you have already done) and grade them as a project, just like the book you will be writing shortly!

Fourth list
window panes for Organic compounds:1. Carbohydrate- organic compound made up of carbon, hydrogen and oxygen atoms whose primary job is to provide a quick source of energy to the organisms that consume it.2. Lipid- organic compound made up of carbon, hydrogen, and oxygen. It has two main purposes in organisms: provide storage for energy and build membranes ( thin covering around all of your cells).3. Protein- organic compound made up of carbon, hydrogen, oxygen, nitrogen and sometimes sulfur atoms. The main jobs of proteins are: to build tissue in the body, to make up hormones and to build enzymes.4. Nucleic acids- organic compounds made up of carbon, hydrogen, oxygen, nitrogen and phosphorous. The main job of these compounds is to carry our genetic code which determines everything that is made in our bodies. Examples are DNA ( deoxyribonucleic acid) and RNA ( ribonucleic acid)5.Hormone- a chemical signal (made out of proteins) that travels through our bloodstream and lets other parts of our body know how to grow or what to make. (ex. progesterone- a hormone that is active in pregnant women and helps to prepare the mom's body to hold and care for a baby).6. Enzyme- a type of protein that is responsible for helping to speed up chemical reactions in our body. In chemistry, or in reactions outside of our body, this is called a catalyst.7. monosaccharide- a simple sugar (carbohydrate), this is a sugar composed of only one molecule- glucose is a monsaccharide. (mono=one)8. polysaccharide- a type of sugar made up of a long chain of single sugars. (poly = many)9. cellulose- a type of sugar found only in plants, it helps to build outer coverings of vegetation ( the yellow shell of each little piece of corn is made of this). we can not digest cellulose.10. Starch- a complex carbohydrate made up a really long chain of glucose molecules. This is the form that plants store their sugar in.11.Insulin- a hormone made in the pancrease that helps break down sugar in the body.12.Hemoglobin- a protein that makes up your blood, it carries iron and oxygen ( you can normally carry 4 molecules of oxygen on each cell).13. Glycogen- the stored form of glucose, it is stored in our liver.14.monomer- a molecule that exists by itself - only one molecule of something = glucose15. polymer- a molecule that exists as a long chain of monomers connected by bonds= starch16. Organic compounds- compounds that have the element carbon as the central/ essential connection.17. atom- smallest unit of an element.18. nucleotide- smalles functional unit (or piece) of a nucleic acid. It consists of a sugar, a phosphate and a nitrogen base.19. double helix- the shape of a DNA molecule, it resembles a twisted ladder.20. single helix- the shape of a RNA molecule, it resembles half of a twisted ladder.

this week and next week in biology
We are now moving from ecology to biochemistry, "the cell" and transport in and out of the cell.
This site should help with the cell and then again when we get to genetics.
It's a great site- I think you'll like the interactives!
http://learn.genetics.utah.edu/content/begin/cells/
check out the size comparison, the membranes and inside a cell.

third set of window panes (10)
biology terms for third set of window panes - due on Tuesday 9-14-10
biology terms1.Logistic growth- when a population of organisms grows at a steady pace until it reaches its carrying capacity, then it levels off. (graph with an s-curve)2.Exponential growth- when a population of organisms grows very rapidly because it has unlimited resources ( graph with a j-curve)3.Stewardship- when people take responsibility for their environment and do things to minimize the negative impact humans have on the environment- like a protector for the environment.4.Sustainable practices- using energy sources that are renewable and that don’t harm the environment. (wind power, hydroelectric power and solar power are examples of sustainable practices).5.Invasive species- organisms that currently live in an area they are not naturally found, they do not have any natural predators and can grow out of control- they usually take over the habitat of another organism that is normally found in the area. (examples are: fire ants, kudzu, rabbits in Australia, the cane toad, northern snakehead)6.Bioaccumulation- a build up of toxins in the tissue of an organism, top predators are most affected.7.Acid rain= http://www.epa.gov/acidrain/education/site_students/whatisacid.html sulfur dioxide and nitrogen oxides mix together to turn rain acidic- tree tops in the mountains look as if they have been burned8.Greenhouse effect- when Ultraviolet (UV) rays get stuck inside Earth’s atmosphere because a thicker shell of atmospheric gases has accumulated in the atmosphere due to pollution.9.Climate change- when the patterns of temperature and weather change over a large area due to the “greenhouse effect”10.Deforestation- when a large wooded area is cleared, either by “clear cutting” or burning, this results in greater amounts of carbon dioxide accumulation in the atmosphere.

Extra Credit guidelines
Here's what you do:
Watch a documentary that is "life science" based. While physics, astronomy and chemistry are useful and interesting, they won't help you in my class.
Examples of good programs are things you might find on National geographic, pbs, bbc, animal planet, planet green and the science channel. Many of these programs can be watched on your computer at your leisure.
You can complete four per each 6 week grading period.
You are basically summarizing what you watched. Write a sentence or two during commercials, or every 10 minutes if it's online, to describe what's happening in the documentary. At the end let me know the overall purpose or intent of the documentary and what you got out of it. It's meant to be a reflection on what you just watched.
TRY TO CHOOSE THINGS THAT WILL HELP YOU IN MY CLASS!
Topics we'll be covering in class: the cell, genetics, heredity, ecology, organic compounds, health and disease, classification of living organism, protein synthesis, plant structure and reproduction.
MAN VS. WILD is acceptable once every 6 weeks grading period. (NOT MYTHBUSTERS, sorry)
ANYTHING ON GENETICS IS GOLDEN!!!!! I MAY EVEN UP YOUR POINTS EARNED IF YOU CHOOSE THIS TOPIC!!
ENJOY!
