FC: Andrew Huang and Sabrina Noriega | Cell Theory Project
1: Three Principles of Cell Theory | -All organisms consist of one or more cells. -All organisms are composed of cells. -Cells come from other existing cells.
2: Schleiden created the Cell Theory stating that all organisms are formed and composed of cells. | Robert Hooke discovered cells when cutting cork under a microscope. Without him we would not have known about cells.
3: Theodor Schwann was a German cell biologist who discovered the digestive enzyme pepsin. He examined animal tissue and extended Schleidan's cell theory, that all living things are made of cells, to animals, including plants. | Rudolph Virchow created the theory that cells are made from other cells.
4: Prokaryotic cells differ from Eukaryotic cells in many ways. They don't have a nucleus and usually have a cell wall. Because they have no nucleus their genetic information is stored in a plasmid. They reproduce in binary fission and are usually decomposers. | Three shapes are: rod shaped, spiral, and spherical, | Examples would be bacterias like Salmonella and E. Coli.
5: Eukaryotic Cells are found in both plants and animals. They contain a nucleus and many other organelles and a membrane. The nucleus houses the DNA which gives Eukaryotic it's name. This cell is 10 times the size of an Prokaryotic cell.
6: Plant Cells | The cell membrane of this cell is surrounded by a cell wall, helping the cell maintain its shape. This cell contains chloroplasts that make food through photosynthesis. Like the animal cell, it has a nucleus and mitochondria.
7: The Animal cell contains a nucleus, like the Plant cell, which houses DNA, cell membrane and Golgi Apparatus. Because the cell wall is absent, it allows to adapt different shapes. | Animal Cells
8: The Ten Cell Structures | Nucleus- Brain of the cell. Contains genetic information and acts as a control center for the cell | The mitochondrion gives energy to the cell using ATP as a chemical energy. | Chloroplasts are similar to the animal cell's mitochondrion. It gives energy by allowing photosynthesis in plant cells. | The cell wall protects organelles and provides structure for the plant cell. | The rough ER transports proteins made from the ribosomes attached to it. The smooth ER transports lipids and does not have ribosomes on it.
9: The Cytoplasm is mainly made up of water and proteins. This is where most cell activity occurs and where the cell structures are located. | Ribosomes synthesize proteins and are either attached to the Rough ER or are in the cytoplasm. | The golgi apparatus takes the proteins made from the Rough ER and packages and distributes them. | The Lysosome breaks down waste in the cell. | The vacuole stores water and energy for the plant cell.
10: The cell membrane is a membrane that separates the inside of the cell and the outside, like a protective barrier, so that both of the environments can be different.
11: Homeostasis is the state of having internal balance and having a stable condition. It is the cell's function to try to maintain this state.
