| Question | Answer |
|---|---|
| element | the basic materials of earth that can not be broken down into simpler substances |
| atom | the smallest amount of any element |
| acid | If the pH is less than 7 the substance is |
| base | If the pH is greater than 7 the substance is |
| Hooke | discovered cells and named them |
| Dyardin | Frenchman, said that cells were living things/ alive |
| Schleiden | he studied plants and observed that all plants are made up of cells. |
| Schwann | made similar observations on animals being made of cells |
| Virchow | all cells arise from cells" |
| 5 specializations of to a cell? | cells, tissues, organs cells, organisms |
| Specialization | Division of labor/ dividing up the work (Advantages: You get better at what you do, diving work, trading off, getting better at what they are doing every time. ) |
| Interdependence | when you are seperated from all of those you depend on you die. |
| cell | the basic unit of living organisms(p.171) |
| cell theory | made up of three main ideas, all organisms are composed of one or more cells, the cell is the basic unit of structure and organization or organisms, all cells come fro preexisting cells. (p.172) |
| compound light microscope | they use a series of lenses to magnify objects in steps(p.171) |
| electron microscope | uses a beam of electrons instead of light to magnify structures up to 500,000 times their actual size.(p.172) |
| eukaryote | most multicellular organisms are made up of these. nucleus is there(p.173) |
| nucleus | responsible for cell division before nucleus(p.174) |
| organelle | all cells contain these small, specialized structures(p.173) |
| prokaryote | Unicellular organisms do not have membrane bound organelles which make them prokaryotes (p.173) |
| cell wall | fairly rigid structure located outside of the plasma membrane that provides additional support and protection(p.179) |
| chlorophyll | traps light energy and gives leaves and stems their green color(p.184) |
| chloroplast | cell organelles that capture light energy and convert it to chemical energy(p.184) |
| chromatin | strands of genetic material, DNA.(p.180) |
| cilia | short numerous projections that look like hairs(p.187) |
| cytoplasm | clear, gelatinous fluid inside a cell.(p.181) |
| cytoskeleton | port structure within the cytoplasm(p.185) |
| endoplasmic reticulum | the site of cellular chemical reactions(p.181) |
| flagella | longer projections that moves with a whip |
| Golgi apparatus | a flattened stack of tubular membranes that modifies the proteins(p.182) |
| lysosome | organelles that contain digestive enzymes(p.183) |
| microfilament | smaller solid, protein fibers.(p.185) |
| microtubule | are thin, hollow cylinders made of protein.(p.185) |
| mitochondria | membrane |
| nucleolus | prominent organelle (p.181) |
| plastid | plant organelles.(p.184) |
| ribosome | the sites where the cell produces proteins according to the directions of the DNA. (p.181) |
| vacuole | membrane |
