FC: Cell Theory | By:Taylor Patterson and Majestie Robinson
1: 1. All organisms are composed of one or more cells. 2. The cell is a basic unit of life. 3. New cells arise only from cells that already exist.
2: Constributions of four scientist | Matthias Schlieden – In 1838, he thought that the cell and nucleus development were closely related. He decided that each plant cell leads to a double life.
3: Robert Hooke – In 1662, he observed tiny compartments in the cork of a mature tree and gave them the Latin name cellulae (meaning small rooms). This was the origin of the biological term cell.
4: Rudolf Virchow – In 1849, his studies of cell growth and reproduction of two cells. He concluded that every cell comes from an already existing cell. | Theodor Schwann – In 1839, he studied the structure and growth of animal tissues, he thought that animals and plants consist of cells and products.
5: heodor Schwann – In 1839, studying the structure and growth of animal tissues, he thought that animals,and plants. they consist of cells and products.
6: prokaryotic vs eukaryotic cells Prokaryotic- cell wall, square shaped smaller that eukaryotes. Eukaryotic - nucleus, nucleous, nuclear membrane and internal membranes.
8: plant vs animal cells | large central vacuole , amyloplast, raphido crystal, vacuole membrane, druse crystal.
9: pinocytotic vessicle, centrioles
10: Ten cell structures | 1: NUCLEUS- it is the "brain" of the cell. it stores genetic info and acts as the control part for the cell and organelles. 2: MITOCHONDRIA- the powerhouse of the cell. without any power, the cell wouldn't live. 3: CHLOROPLASTS- As in animals, chloroplasts (along with mitochondria) supply power to the plant cell 4: CELL WALL- the cell wall protects the organelles in the cytoplasm from other objects. 5: CELL MEMBRANE- since the cell membrane plays a major role in osmosis and such, I would say it's pretty important.
11: 6: ENDOPLASMIC RETICULUM- the transport of proteins to the nucleus is very important. 7: RIBOSOMES- the proteins need to be made somewhere, and this is where. 8: GOLGI APPARATUS- this is the packaging and distribution center of the cell. When something needs to be "taken out", like waste, this is the organelle that helps. 9: LYSOSOME- these pair with the Golgi apparatus to get rid of waste. They are the suicidal organelles that take out the trash. 10: VACUOLE- even though it's last, the vacuole holds important material like water, power, etc.
12: The cell membrane controls what goes in and out of the cell. It takes in and releases materials Both plants and animal cell have a cell membrane. A cell membrane is located beneath the cell wall in plants... and on the outer surface of a cell on a animal cell. | Cell Membrane
13: the process that maintains balance or equilibrium of an organism's internal environment. | Homeostasis
