 Cell Theory

**The Cell Theory** 1.All living things are made of cells. 2.Cells are the basic units of structure and functioning in living things. 3.Living cells come only from other living cells.

Hooke- observed pieces of cork. He coin the word cell Leeuwenhoek- he discovered small organisms he call animalcules, he discovered bacteria Schleiden-discovered that all plants were made of cells Schwann- animals are made of cells Virchow- cell come only from living things
 * The Scientists **

Cell Membrane-Decides what can enter in leave a cell Nucleus-Controls the cell Cytoplasm-gel like substance that fills a cell Ribosomes-make proteins Endoplasmic Reticulum- Changes the proteins and sends them to other organelles Golgi Bodies-Changes the protein and send them out the cell Vacuoles-Storage rooms inside cells Mitochondria-break down sugars to release power house Cytoskeleton- supports the cell
 * Cell Parts **

//**Moving Materials**//  -Osmosis:Moves h2o molecules from high to low conc. to low conc. -Diffusion: Moves molecules from high to low conc. Moves Everyhing but water.
 * Cell Processes**
 * Passive Transport:

>   -Transport Proteins:in cell membrane from low to high -Transport Engulfing: Cells swallows particules.
 * Active Transport:

//**Mitosis**// P-prophase M-metaphase A-anaphase T-telophase I-interphase

//**Creating Energy: Cellular Respiration**// Needs: Creates:**
