 Cell Theory

**The Cell Theory** 1. All living things are made of cells.

2. Cells are the smallest unit of life 3.Living cells come only from other living cells.

Hooke-First to use the word cell. Leeuwenhoek-Discovered animalcules & Bacteria. Schleiden-All plants are made or cells Schwann-All animals are made of cells. Virchow-Cells come from other cells.
 * The Scientists **

Cell Membrane-allows some things to pass in to or out the cell it keep out others Nucleus-controls the cell Cytoplasm-gel-like substance that fills a cell Ribosomes- Makes proteins Endoplasmic Reticulum-changes that proteins and sendas them to other organells Golgi Bodies-changes proteins and sends them out of them cell Vacuoles-store chemical in the cell Mitochondria-Breaks down sugar to relase energy aka power house Cytoskeleton-supports the cells
 * Cell Parts **

//**Moving Materials**// >   -Osmosis: Moves WATER molecules.
 * Cell Processes**
 * Passive Transport: Does not use energy

-Diffusion: Moves molecules like oxygen and carbon dioxide across the cell’s membrane.

>   -Transport Proteins: Proteins in the membrane that “pick up” molecules and transport them into the cell.
 * Active Transport: Does uses energy

-Transport Engulfing: The cell surrounds a food molecule, creates a vacuole around the molecule and brings it into itself.

//**Mitosis**// P-Prophase A.Duplicale DNA. B.Move centriols to right place. M-Metaphase-A. DNA makes chromosomes B.Chromosomes line up in middle. C. Spindle fibers attack to the centromere. A-Anaphase-Half of the chromosomes are pulled to one side of the cell; half go the other way. 1/2 Chromosomes go one way,1/2go the other. T-Telophase-Cell membrane closes and Splits the cell into two pieces. Membrane Closes. I-Interphase-Resting State.

//**Creating Energy: Cellular Respiration**// Needs:Sugar and Oxygen Creates:Carbon,Water,Energy**
 * Takes place in:Mitochondria
