|---|---|
 Robert Hooke | First to observe and name cells underneath the microscope. Observed a cork and saw plant cells. |
| Anton van Leeuwenhoek | First to observe single celled organisms. |
| Matthias Schleiden | All plants are made of cells. |
| Theodor Schwann | All animals are made of cells. |
| Rudolf Virchow | Cells only formed from existing cells. |
| Cell Theory 3 ideas | All living things composed of cells, cells basic unit of structure and function in living things, all cells are produced from other cells |
| Cell membrane (3) | Outer boundary, protects, controls what enters and leaves |
| Cell wall (4) | Only in plant cells, protection and support, made of cellulose, allows water and dissolved substances to pass through |
| Nucleus (3) | Controls most activity, controls all genetic info in form of DNA, controls nuclear membrane which protects it |
| Chromatin (1) | Contain genetic material which hold instructions to direct cell |
| Nucleolus (1) | Where ribosomes are made |
| Cytoplasm (1) | Clear fluid |
| Endoplasmic Reticulum (3) | Series of folded membrane that form sacs or tubes, carry proteins and other materials to cell parts, rough has ribosomes |
| Ribosomes (3) | Makes proteins which are transported to golgi bodies, in cytoplasm or rough ER, all cells must produce protein |
| Golgi bodies (2) | Storing and packing of proteins and other chemicals, mailroom |
| Mitochondria (4) | Produce energy, powerhouse, many in muscles, sausage shape |
| Chloroplasts (3) | Only in plants, perform photosynthesis, contain chlorophyll pigment |
| Vacuoles (3) | Store food water or waste, plant cells have large ones that store water, some plants dont have them |
| Lysosomes (2) | created in golgi bodies and help with digestion |
| Bacterial cells (4) | very small, cell wall and membrane, no nucleus, have ribosomes |
| Diffusion | Tendency of molecules to move from a higher concentration to a lower concentration until equilibrium is reached. |
| Osmosis | Diffusion of water |
| Active Transport | Uses energy to move things in and out with transport proteins |
| hypertonic solution | higher concentration of solute, cell shrivels |
| hypotonic solution | lower concentration of solute, cell expands |
| isotonic solution | Equal amounts of solute |
