Cells Theory, Types, Organelles, and Structure as related to Function
Theory • The Wacky Cell Theory • So, the Cell Theory states: • All organisms are made of cells • All existing cells are produced by other living cells • The cell is the most basic unit of life
Contributors Schleiden • Hook Schwann Leewenhoek Hooke- the 1st to identify and name cells Leewenhoek- made better lenses so was able to see cells in greater detail Schleiden-found that plants are made of cells Schwann- concluded that all living things are made of cells Virchow- proposed that all cells come from other cells Virchow
Cells • Prokaryotic Cells
Cells • Prokaryotic cells do NOT have a nucleus or other membrane-bound organelles. The DNA is suspended in the cytoplasm. All prokaryotes are microscopic single cell organisms.
Cells • Eukaryotic Cells
Cells • Eukaryotic Cells have a nucleus and other membrane-bound organelles. The nucleus is the largest organelle and encloses the genetic information. Eukaryotes may be multicellular or single celled organisms.
Graphic Organizer • You make it…..NOW. • Move over to the lab tables • find a spot and • make a graphic organizer according to your notes • Use the “butcher” paper provided • Put your name, date, class period at the top.
Organelles cytoskeleton nucleusvesicle Endoplasmic reticulumribosomecentriole Golgi apparatus mitochondrion Lysosomecell wallchloroplast vacuole
Cytoskeleton • You and your partners will add this information on all the organelles in class and the best of the PP slides will be posted here.
For Example Golgi Apparatus (Body) • Consist of closely layered stacks of membrane enclosed spaces • Packages proteins • Sorts and stores some of them for later • Transports others to other organelles in the cell
Cells in Comparison • How SMALL is a cell anyway?
