Cells and Membrane Transport Passarelli
Terms : Hide Images [1]
| membrane bound organelle that contains the DNA (instructions for making protein) and controls the activities of the cell | ||
| site of protein synthesis | ||
| site of photosynthesis; sugar/glucose is made here | ||
| site of cellular respiration; energy/ ATP production | ||
| storage | ||
| protects cell; found in plant cells and bacterial cells; made of cellulose | ||
| aka plasma membrane; regulates what goes into and out of cell; made of phospholipids | ||
| no nucleus | ||
| has a nucleus | ||
| unspecialized cells capable of undergoing differentiation | ||
| process in which cell takes on specific function | ||
| aka channel protein; allows large substances to move through membrane; used in facilitated diffusion | ||
| found on surface of cell; used in signaling between cells | ||
| maintaining constant internal environment despite changes in external environment | ||
| passive transport of water; water moves to where solute is more concentrated | ||
| movement of solutes along concentration gradient (from higher to lower concentration) | ||
| movement of substances against the concentration; requires energy from cell | ||
| requires no energy from cell; movement of substances along its concentration gradient | ||
| movement across membrane through a transport protein |
