| the celis outer boundary | ||
| region of the cell inside the plasma membrane that includes the fluid | ||
| part of cytoplasm that includes molecules and small particles | ||
| membrane structure that contains a celis DNA | ||
| organisms made up of one or more cels that have a nucleus | ||
| well defined intracellular bodies that perform certain functions in a cell | ||
| a group of similar cells and their products | ||
| groups of tissues that perform certain jobs | ||
| a group of organs that accomplish related tasks | ||
| a double layer of phospholipids lining up | ||
| when a cell is about to divide, the chromatin condenses | ||
| double membrane surrounding the nucleus | ||
| denser area in the nuclei | ||
| organelles made of protein and RNA that are direct protein synthesis in the cytoplasm | ||
| tiny organelles that transfer energy from organic molecules to ATP | ||
| system of membranous tubes and sacs called cisternae | ||
| system of flattened membranous sacs | ||
| vesicles that bud from the golgi apparatus and contain digestie enzymes | ||
| net work of thin tubes and filaments that crisscross the cytosol | ||
| hollow tubes made of tubulin (protein) | ||
| long threads of bead like protein actin and are linked end to end and wrapped around each other | ||
| hair like structures that extend from the surface of the cell | ||
| two short cylinders of microtubules at right angles to each other and are situated in the cytoplasm | ||
| crossing the cell membrane without any input of energy by the cell | ||
| movement of molecules from an area of higher concentration of molecules across a distance | ||
| concentration of molecules will be the same throughout the space the molecules occupy | ||
| process by which water molecules diffuse across an area of higher concentration to an area of lower concentration | ||
| solution whose solute concentration is lower than the solute concentration inside a cell | ||
| solution whose solute is higher than the solute molecules is higher outside than inside | ||
| concentration of solutes outside & inside are equal | ||
| organelles that remove water | ||
| pressure that water molecules exert against the cell water | ||
| cells shrink away, and tugor pressure is lost | ||
| the bursting of cells | ||
| passive transport | ||
| movement of these kinds of molecules across the membrane is dissisted by | ||
| transport that involves proteins | ||
| movement from higher concentration to lower | ||
| process by which cells ingest external fluid | ||
| example of active transport in animal cells involves a carrier protein | ||
| when membrane-bound organelle breaks off from the cell | ||
| transport of solutes or fluids | ||
| movement of large particles or whole cells | ||
| lysosomes to figure with the vesicle that contain the ingested bacteria and viruses | ||
| process where a substance is released from the cell through a vesicle |
