| Question | Answer |
|---|---|
| Cell | Basic unit of life |
| Cell theory | Fundamental concept of biology |
| Nucleus | Large membrane-enclosed structure that contains the cell's genetic material in the form of DNA |
| Eukaryotes | Cells that contain nuclei |
| Prokaryotes | Cell that do not contain nuclei |
| Organelles | little organs |
| Cytoplasm | Portion of the cell outside the nucleus |
| Nuclear envelope | Composed of two membranes |
| Chromatin | Granular material you can see in the nucleus |
| Chromosomes | When a cell is divided |
| Nucleolus | Where the assembly of ribosomes begins |
| Ribosomes | Small particles of RNA and protein found through out the cytoplasm |
| Endoplasmic reticulum | Site where lipid components of the cell membrane are assembled, along with proteins and other materials that are exported from the cell |
| Golgi apparatus | Modifies proteins and other materials from the endoplasmic reticulum for storage in the cell. |
| Lysosomes | Small organelles filled with enzymes |
| Vacuoles | Store materials such as water,salts,proteins,and carbohydrates. |
| Mitochondria | Organelles that convert the chemical energy stored in food into compounds that are more convenient for the cell to use. |
| Chloroplasts | Organelles that capture the energy from sunlight and convert it into chemical energy |
| Cytoskeleton | Network of protein filaments that helps the cell to maintain its shape. |
| Centrioles | Located near the nucleus to help organize cell division |
| Cell membrane | Cell wall |
| Cell wall | Strong supporting layer around the membrane |
| Lipid bilayer | Composition of nearly all cell membrane |
| Concentration | Mass of solute in a given volume of solution or mass/volume |
| Diffusion | As a particle moves |
| Equilibrium | COncentration of the solute is the same throughout a system |
| Osmosis | Diffusion of water through a selectively permeable membrane |
| Isotonic | Same strength |
| Hypertonic | Above strength |
| Hypotonic | Below strength |
| Facilitated diffusion | Molecules that cannot diffuse across the cell membrane's lipid bilayer on there own |
| Active transport | Cells sometimes must move materials in the opposite direction against a concentration difference |
| Endocytosis | Process of taking material into the cell by means of infoldings, or pockets, of the cell membrane |
| Phagocytosis | Cell eating |
| Pinocytosis | Fill with liquid and pinch off to form vacuoles within the cell |
| Exocytosis | Membrane of the vacuole surrounding the material fuses with the cell membrane, forcing the contents out of the cell |
| Cell specialization | Cells throughout an organism can develop in different ways to perform different tasks |
| Tissue | Group of similar cells that perform a particular function |
| Organ | Many groups of tissue work together as an organ |
| Organ system | completes a series of specialized tasks. |
