| Robert Hooke | invented the light microsope |
| Anton Van Leeuwenhoek | invented single lense microscope |
| cell | basic unit of life |
| Cell theory | 1. All living things are composed of cells 2. cells are basic units of structure and function 3 new cells are produced from existing cells |
| Matthias Scleiden belived | All plants were made of cells |
| Theodore Schwann belived | All animals were made up of cells |
| Rudolf Virchow | New cells could be produced only by the division of existing cells |
| light microscopy | light to detect small objects |
| electron microscopy | uses a beem of electrons to detect objects |
| TEM | Transmition electron Microscope |
| SEM | Scanning electron Microscope |
| scanning prob microscope | scanns object to have a 3D immage |
| similarites b/t prokaryotic and eukaryoitic | they both have a neclius and genetic information |
| Prokaryotes | genetic matirial that is not contained in the neuclius |
| eukaryotes | a necelus in which genetic matiral is sparated form the rest of the cell |
| cell=factory? | when you first look it looks complicated but look closely and patterns emmerge |
| Cell membrane | regulates what enters and leaves the cell/protection and support |
| Cell walls | provide protection/support for the cell |
| Golgi Apparatus | to package and sort to be secreeted or to be stored |
| The neculius | contains the DNA and instructions on making proteins and other important molicules |
| nuceolus | produces ribosonzes |
| cytoplasm | to maintain the shape, the consistency of the cell and to provide suspension to the organelles. |
| Mitochondria | organelles that convert the chemical energy stored in food into compunds that are more convienient for the cell to use |
| Chloroplast only found in what type of cells? | plant |
| organelles | specialized subunits within a cell |
| endosybiosys theory | The endosymbiotic theory concerns the origins of mitochondria and chloroplasts, which are organelles of eukaryotic cells. |
| Ribosomes | proteins assembled on it |
| endoplasimic reticulm | site where lipid compontents of the cell memberane are assembled along with proteins and other materials that are exported from the cell |
| lysosomes | digestion or the breaking down of lipids |
| vacuoles | store material such as water, salts, protiens and carbs |
| Chloroplasts | allow photo sythasis |
| cytoskeleton | helps maintain cell's shape |
| aminal cells | red blood cells |
| plant cells | sunlight |
| diffusion | process of molicules going from high concentration to to low consentration |
| equillibrium | consentration of solute is the same throughout the system |
| permiable | can be penitrated |
| imperiable | can't be penitrated |
| Osmosis | the difusion of watter through a selectivley periable membrane |
| isotonic | refering to muscles |
| Hypetonic | above strength |
| hypotonic | below strength |
| facilitated difusion | Having channels to allow some elements to enter |
| active transport | needing energy |
| unicellular organisms | one cell |
| multicellular organisms | many cells |
| cell specialization | The cell performing a specific function for a larger organ or tissue. |
| specialied plant cells | stoma guard cells |
| 4 types of tissues | muscles epitheal nervous conective |
| organ systems | A group of organs that work together to carry out a particular task. |
| 11 organ systems | 1. nervous 2 skelital 3 muscular 4. integumentary 5 digestive 6 respatory 7 circulatory 8 endoctrine 9 excretory 10. reproductive 11. immune |
