FC: CELLS: The Basic Unit of Life | BY: Neel & Rishi
1: Cell Theory | The Three Principles | 1: Cells Are The Basic Unit Of Life 2: All Living Things Are Made Of Cells 3: All Cells Are Produced By Existing Cells
2: Contributions Of Four Scientists | Theodor Schwann And Matthias Jakob Schleiden: Schwann and Schleiden suggested that all cells are the basic unit of life. Rudolf Virchow: Concluded that all cells came from pre-existing cells Robert Hooke: Discovered the cell.
3: Prokaryotic vs. Eukariotic Cells | Prokaryotic:Usually bacteria, originated 3.5 billion years ago. Eukaryotic:Found in plants and animals, originated 1.5 billion years ago. | Prokaryote Eukaryote
4: Plant vs. Animal Cells | Plant Cells: Found in plants, has a fixed shape, has a cell wall and chloroplasts. Animal Cells: Found in animals, has no fixed shape, has no cell wall and does not make it's own food. | Animal Cell Plant Cell
5: Ten Cell Structures | Nucleus: A sphere at the center of the cell. Contains RNA and DNA. Nuclear Membrane: Surrounds the Nucleus, helps move things to and from the Nucleus. Chloroplast: This is where photosynthesis occurs. Cytoskeleton: Provides for the movement and structure of the cell. Golgi Apparatus: Packaging/ distribution center of the cell. Lysosome: Digestive system of the cell.
6: Ribosome: Makes the cell's protein. Vacuole: Sacs that are used for storage, digestion, and waste removal. Cell wall: Most commonly found in plants, surrounds plasma membrane. Plasma membrane: Outer cell membrane that controls what goes in or out of the cell. | Cell Membrane | The cell membrane is usually a flexible lipid bilayer that is part of the cell wall.
7: Homeostasis | Homeostasis is the process in which all living things try to maintain a stable internal environment.
