Definition
| Smallest filaments, dynamic and changing web that supports the surface of the cell. Important for movement and transport. |
|
|
Term
|
Definition
| Medium sized permanent filaments composed of strands of fibrous proteins wound together. Maintain shape and anchor organelles in place. (e.g. keratin found in hair, nails, and skin). |
|
|

| Help move structures across the surface, are shorter than flagella and appear in large numbers. |
|
|
Term
|
Definition
| Found at the base of cilia or flagella. 9 microtubule triplets. |

| Extension of the plasma membrane that help with absorption by increasing the surface area of a cell. |
|
|
Term
|
Definition
| Organelle that produces energy (ATP) for the cell. |

|
Term
|
Definition
| Site where protein is made. Made up of proteins and ribosomal RNA (rRNA). Can be free or attached. |
|
|
Term
|
Definition
| Single ribosomes that are floating in the cell. Site where protein is made. |
|
|
Term
|
Definition
| Group of ribosomes that are linked together by mRNA and is a site of protein synthesis. |
|
|
Term
| Rough Endoplasmic Reticulum |
|
Definition
| Covered with ribosomes and site where protein is made. Transport vesicles of protein are pinched off from the rough ER and moved to different places in the cell. |
|
|
Term
| Smooth Endoplasmic Reticulum |
|
Definition
| Makes lipid and steroid molecules. Aids in fat metabolism and drug detoxification. |
|
|
Term
|
Definition
| Contain proteins produced in the rough ER and travel to the Golgi apparatus. |
|
|
Term
|
Definition
| Site that receives transport vesicles from the rough ER. Changes, sorts and packages proteins into different types of vesicles before they are sent out to different parts of the cell. |
|
|
Term
|
Definition
| Made in Golgi apparatus. Have proteins that are ready to move outside of cell. |
|
|
Term
|
Definition
| Rid the body of free radicals and other toxins. |
|
|
Term
|
Definition
| Membrane bound vesicles that come from the Golgi apparatus and contain enzymes that rid the body of worn-out organelles, stressed or dead cells. |
|
|
Term
|
Definition
| Small barrell-shaped structures composed of 9 evenly spaced sets of triplets of microtubules. |
|
|
Term
|
Definition
| Organelle near the nucleus of a cell that contains two centrioles oriented at right angles from one another and from which the spindle fibers develop in cell division. |
|
|
Term
|
Definition
| Control center of the cell. Surrounded by the nuclear envelope and contains the nucleoli and chromatin. Houses DNA and makes ribosomes. |
|
|
Term
| Nuclear Envelope/Membrane |
