|---|---|
| Hooke | 1665 - discovered cells while looking at cork under a microscope. He was the first to use the term “CELLS”, which means “little rooms” in Latin. |
| Leeuwenhoek | 1675 - discovered unicellular organisms in pond water and named them “animalcules”. |
| Schleiden | 1838 - stated that all plants are made of cells. |
| Schwann | 1839 - stated that all animals are made of cells. |
| Virchow | 1855 - said that all cells develop from other cells. |

| structure and function in living things. | Cells are the basic unit of _____ |
| preexisting cells. | All cells develop from _____ |
| microscope | the invention of the _____ has allowed us to see cells. |
| Organelles | are tiny organs inside of cells that carry out different functions |
| Chloroplasts | are found in plant cells and capture sunlight for photosynthesis; they also give plants their green color because of the chlorophyll inside this organelle |
| cell wall | supports and protects plant cells, like a brick wall |
| cell membrane | is like a door or gate, surrounds ALL cells and controls what enters and leaves the cell |
| mitochondria | are powerhouses of the cell and use oxygen to break down food and release energy |
| ER | is like a city highway or subway; it is the cell’s delivery system |

| cell cycle | is the life cycle of a cell |
| daughter cells | New cells formed at the end of mitosis are called |
| Interphase | the cell grows as organelles and DNA are copied |
| prophase | the nucleus begins to disappear and chromosomes start moving toward the center of the cell |
| metaphase | chromosomes and their copies line up in the middle of the cell |
| anaphase | the chromosomes and their copies are pulled apart to opposite sides of the cell |
| telophase | two new nuclei are formed around the chromosomes |
| cytokinesis | In plant cells, a cell plate forms to divide the cytoplasm. |
