Cell Structure
Prokaryotic and Eukaryotic cells
| Question | Answer |
|---|---|
| cell | basic unit of life |
| Cell Theory | - cells are basic unit of life - all living organisms made of cells - all cell come from pre-existing cells |
| Tissues | interconnected cells |
| Organs | several tissues combined |
| Organ System | organs working together |
| Organsisms | multiple organ systems that function together |
| Magnification | enlarging an object |
| Resolution Power | ability of a microscope to distinguish two adjacent structures as seperate - higher the resolution, the better the clarity and detail of the image |
| Plasma Membrane | seperates the cell's interior from the environment |
| Cytoplasm | made of cytosol in which other components of the cell are suspended |
| Cytosol | liquid that fills the cells -breaks down watse products and moves materials around the cell |
| DNA | the genetic material of the cell |
| Ribosomes | synthesize proteins -where you make protein |
| Cytoplasm | fluid as well as suspended materials |
| Chromatin | DNA and protein are organized into fibrous material |
| Chromosomes | chromatin fibers coil up to be seen as seperate structures |
| Transcription | |
| Translation | |
| Nuclear Envelope | |
| Nucleolus | inside the nucleus where ribosomes are assembled from RNA & proteins |
| Mitochondrion | - powerhouse of the cell |
| Peroxisomes | small rounded organelles enclosed by a membrane -detoxification |
| Endomembrane system | internal membranes and organelles that work together to modify, package, and transport lipids and proteins |
| Endoplasmic Reticulum | interconnected membranous sacs and tubes |
| Golgi Apparatus | series of flattened membranes |
| Cytoskeleton | structure of protein with different functions -Microfilaments - intermediate filaments - Microtubules |
| Where is Cilia and Flagella found? | found in protists, animal cells, and sperm of some plants |
| Cilia & Flagella | made of microtubules arranged in a "wheel" |
| Lysomes | breaks down large biomolecules and even worn-out oranelles |
| Extracellular Matrix | collagens & other fibrous proteins support and connect cells |
| Centrosome | made up of centrioles and produces protein spindle fibers |
| Centrioles | structures that may assist with seperating chromosomes during division |
| Cell Wall | Maintains cell shape |
| Stroma | aqueous fluid |
| Thylakoids | a set of interconnected and stacked fluid-filled membrane sacs |
| Intercellular Junction | provide direct channels of communication between cells |
| Tight Junction | neighboring cells are pressed tightly together |
| Desmosomes | fastens cells together into strong sheets |
| Gap Junction | provide cytoplasmic channels between adjacent cells |
