What are the 6 functions of cells? | 1. Basic unit of life
2. Protection and Support
3. Movement
4. Communication
5. Cell metabolism and energy release
6. Inheritance |
What are Organelles? | "Little organs" within the cells that carry out the basic functions.
Located between the cell membrane and nucleus in the cytoplasm. |
What is the cell membrane/plasma membrane? | The outermost component of the cell.
Functions as a barrier between the extracellular substance (outside) and the intracellular substance (inside) |
What is extracellular substance? | Substances outside of the cell |
What is intracellular substance? | Substances inside of the cell |
What is a Fluid Mosaic Model? | Model used to show the structure and function of the cell membrane |
What is the nucleus? | Cell organelle that contains the hereditary information in the form of DNA
The site where RNA is copied from DNA |
What is the nucleolus? | Place where ribosomes are made.
Center of the Nucleus |
What is the Rough Endoplasmic Reticulum (Rough ER)? | The membraneous network inside the cytoplasm that has ribosomes attached to the surface. |
What is the Smooth Endoplasmic Reticulum (Smooth ER)? | The membraneous network inside the cytoplasm that does not have ribosomes attached. |
What is the Golgi Apparatus? | Stacks of flattened sacks, formed by membranes, that collect, modify, package, and distribute proteins and lipids. |
What are Lysosomes? | Membrane-bound vesicle containing intracellular digestive enzymes |
What is Mitochondrion? | Small, spherical, rod-shaped or thin filamentous structure in the cytoplasm that is a major site of ATP production. |
What are Microtubules? | Hollow structures formed from protein subunits that perform a variety of roles, such as helping to provide support to the cytoplasm, assists in the process of cell division. |
What are Cilia? | They project from the surface of cells, are capable of moving, and vary in number from none to thousands per cell. They move mucus away from the lungs. |
What is the Flagella? | There is usually only one per cell. It functions to propel cells. |
What is the Microvilli? | Specialized extensions of the cell membrane that are supported by microfillaments. |
What are Ribosomes? | Organelles where proteins are produced and synthesized |
What is the Cytoskeleton? | Consists of proteins that support the cell, hold organelles in place, and enable the cell to change shape. |
