| Robert Hooke | discovered cells |
| Van Leeuwenhoek | discovered bacteria cells in pond and in his mouth |
| Schlieden | discovered that all plants are made of cells |
| Schwann | discovered that all animals are made of cells |
| Virchow | discovered that new cells are made from existing cells |
| Cell Theory | 1.all living things are made of cells 2.cells are the basic unit of structure and function in living things 3.new cells are produced from existing cells |
| Ocular lens | eyepiece we look through |
| objective lens | magnify the specimen |
| fine adjustment | makes small changes to focus on medium or high power |
| coarse adjustment | makes large changes to focus on low power |
| nosepiece | holds objective lens and can be rotated to change power |
| stage | platform where slides are placed |
| base | provide support for microscope |
| prokaryotes | no nucleous; DNA is free floating small and simple compared to eukaryotes ex: bateria |
| eukaryotes | DNA is found in the nucleous; large and complex ex: animal |
| organelles | |
| Nucleus | |
| Nucleolus | |
| cytoplasm | between cell membrane and outside of the nucleous gel like substance |
| ribosomes | found in prokaryotes and eukaryotes free floating makes protein |
| rough endoplasmic reticulum | |
| smooth endoplasmic reticulum | |
| golgi apparatus | |
| lysosomes | clean up crew for the cell (think: lysol) can break down a virus |
| vacuole | |
| mitochondria | powerhouse(mighty!) |
| cholorplasts | |
| centrioles | |
| cytosketeton | |
| cell membrane | |
| cell wall | |
| describe how protein is made | |
| explain the difference between plant and animal cells | |
| Somatic Cells | Body Cells |
| Gamete Cells | Sex Cells |
| Haploid | Half the number of Diploid Cells |
| Diploid | Double the number of Hapolid Cells |
| Meiosis 1 | The division of sex cells |
| Meiosis 2 | A second division of sex cells |
| Prophase 1 | DNA has already duplicated and chromosomes get shorter and thicker |
| Metaphase 1 | The Centrioles are at opposite poles of the cell |
| Anaphase 1 | When two chromosomes of each tetrad get split and pulled towards different sides of the cell |
| Telophase 1 | When Haploid cells start to form |
| Prophase 2 | |
| Metaphase 2 | |
| Anaphase 2 | |
| Telophase 2 | |
| Meiosis 2 Cytokinesis | |
