The Cell in its Environment
Selective permeable: some materials can pass through membrane while others can't
Diffusion: main method of movement of particles across the cell membrane
Osmosis: diffusion of water molecules across cell membrane
* the rule for diffusion and osmosis: molecules move from an area of high concentration to an area of low concentration
Equilibrium: balance of molecules
DIFFUSION
*sugar
*salt
*h2o
*co2
*o2
*food
*waste
*drugs/alcohol
(osmosis only water)

Chemical Compounds in Cells
The compound water (H2O) is very important for cells. They use it for chemical reactions. It also gives the cell its shape ans size.
Organic Compounds | Where it comes from | Function is cell |
Carbohydrates | bread, pasta, rice, potatoes | Provide energy |
Lipids | Fats, oils, waxes | Stored energy |
Proteins | Meats, eggs, fish, nuts, beans | Building materials for hair, nails and heal cells |
Nucleic Acids | DNA and RNA | Genetic information in cell |

Cell Organelles
Cells have many parts. But plant cells and animal cells are quite different. In this list you will see the organelles and their functions.
Cell Wall: protects and gives support.
Cell Membrane: controls what substances come in and out of the cell
Nucleus: control center
Cytoplasm: thick jell like fluid that holds organelles in place
Mitochondria: powerhouse/ converts food into energy
Endoplasmic Reticulum: carries proteins and other materials from one place to another
Ribosome: factories that produce proteins
Golgi Bodies: recieve proteins from Endoplasmic Reticulum, package, and distribute them to the cell
Chloroplast: capture energy from the sun and convert into food. (contains chlorophyl)
Vacuole: water and food storage area.
Lysosome: contain chemicals that break down waste in cell
NOTE *animal cells contain everything listed except cell wall and chloroplast.
* plant cells contain everything listed
* in animal cells, there are many small vacuoles, instead in plant cells there is one large vacuole

Project Introduction
Hi! My name is Geno Eguiguren. I'm a thirteen year old girl who lives in Quito, Ecuador. I study at Colegio Menor SFQ. I live with my parents and my brother. My favorite things to do are play soccer, ride horse and spend time with my friends. My best friends are Maria Jose, Valentina, Martina, Juliana and Claudia. They are really cool friends.
My goal is to make people know about cell organelles. I am a scientist who studies plants, animals, and their structures. The National Geographic Magazine hired me to make an investigation about cells to publish it in the June edition. I will also publish my investigation in this blog. My audience will be the readers of this magazine, the scientists I will show my work to, and the blog readers.
My work will be exposed in different ways. In Microsoft Excel I will make a chart of the cell organelles and its functions. In Macromedia Freehand I will make a drawing of a cell, and through this blog, I will write entrees to make my readers know more about my topic. I will also link you to interesting Web Pages, images and games.
I hope you enjoy my work.
If you have any questions or comments, feel free to express them.
Sincerely,
Geno
