| Term | Definition |
|---|---|
| Eubacteria 1 | Bacteria constitute a large domain of prokaryotic microorganisms. Typically a few micrometres in length, bacteria have a number of shapes, ranging from spheres to rods and spirals. |
| Cell 2 | The smallest functional and structural unit of all living organisms;usually consists of a nucleus,cytoplasm,and a membrane |
| Cell theory 3 | a scientific theory which describes the properties of cells |
| Resoulution 4 | the ability to distinguish between two points on an image |
| Cell membrane 5 | A phospholipid later that covers a cell's surface and acts as a barrier between the inside of a cell and the cell's environment |
| Nucleus 6 | In a eukaryotic cell,membrane-bound organelle that cotains the cell's DNA and that has a role in processes such as growth,metabolism,and reproduction |
| Prokaryotic 7 | an organism whose cell lacks a true nucleus |
| Organelle 8 | One of the small bodies in a cell's cytoplasm that are specialized to preform a specific function |
| Compound light microscope 9 | An instrument that magnifies small objects so that they can be seen easily by using two or more lenses |
| Magnification 10 | the act or process of enlarging the physical appearance or image of something |
| Convex lens 11 | this type of lens is thicker in the center than at the edge |
| Electron microscope 12 | A microscope that focuses a beam of electrons to magnify objects |
| Archaebacteria 13 | common name for a group of one-celled organisms many of which don't need oxygen or sunlight to live |
| Eukaryotic 14 | these cells have a distinct membrane bound nucleus |
| Organelle 15 | one of the small bodies in cell's cytoplasm that are specialized to preform a specific function |
| Cell membrane 16 | A phospholipid later that covers a cell's surface and acts as a barrier between the inside of a cell and the cell's environment |
| Chromatin 17 | is the combination or complex of DNA and proteins that make up the contents of the nucleus of a cell |
| Ribsome 18 | a sphere-shaped structure within the cytoplasm of a cell that is made of RNA and protein and is the site of protein synthesis |
| Chloroplast 19 | the combination of plastid (an organelle in an plant cell) and chloros (which means green) |
| Lysosome 20 | a membrane bound cell organelle found in animal cells |
| Hydrophobic 21 | refers to the physical property of a molecule that repels water |
| Endoplasmic Reticulum 22 | a network of tubular membranes in the cytoplasm of the cell |
| Golgi complex (apparatus,body) 23 | a net like structure in the cytoplasm of animal cells |
| Nuclear membrane 24 | the double layered membrane surrounding the nucleus of eukaryotic cell |
| Chromosomes 25 | a structure within a cell that has the genetic material as a threadlike linear strand of DNA bonded to various proteins in the nucleus of eukaryotic cells |
| Mitochondria 26 | known as the powerhouse -these organelles catlike a digestive system which takes in nutrients,breaks them down,and creates energy rich molecules for the cell |
| Cell wall 27 | an thin membrane around the cytoplasm of a cell;controls subtances going in and out of a cell |
| Nucleus 28 | In a eukaryotic cell,membrane-bound organelle that cotains the cell's DNA and that has a role in processes such as growth,metabolism,and reproduction |
| Cytoplasm 29 | the fluid that fills a cell |
| Golgi body 30 | an organelle that takes up and processes secretary and synthetic products from the endoplasmic reticulum |
| Vacuole 31 | a membrane -bound cavity within a cell,often containing watery liquid or secretion |
| Vesicle 32 | a small bubble within a cell |
| Cytoskeleton 33 | helps the cell maintain it's shape,aids in cellular movement |
| Nucleolus 34 | control center of the cell and contains chromosomes |
| Chlorophyll 35 | a green pigment,in all green plants and in cyanobacteria,responsible for the absorption of light to provide energy for photosynthesis |
| Tissues 36 | any of the distinct types of material which animals or plants are made,consisting of specialized cells and their products |
| Organs 37 | a part of an organism that is typically self-contained and has a specific vital function |
| Organ systems 38 | a group of organs that work together to perform one or more functions |
| Organism 39 | an individual animal,plant,or single celled life form |
| Unicellular 40 | consisting of a single cell |
| Multicellular 41 | having or consisting of many cells |
| Structure 42 | an arrangement or organization of parts to form an organ,system ,or living thing |
| Function 43 | the reason some object or process occurred in a system that evolved through a process of selection or natural selection |
| hydrophilic 44 | a molecule or functional group that forms strong hydrogen bonds with water |
