| Question | Answer |
|---|---|
| cell | the basic structural and functional unit of all living organisms |
| cell theory | one of the fundamental ideas of modern biology |
| plasma membrane | special boundary that controls what enters and leaves the cell |
| organelles | specialized structures that carry out specific cell functions |
| eukaryotic cells | contain a nucleus and other organelles that are bound by membranes |
| nucleus | central organelle that contains the cell's genetic material in the form of DNA. |
| prokaryotic cells | cells without a nucleus or other membrane-bound organelles |
| selective permeability | membrane allows some substance to pass through, but keeps others out |
| phospholipid bilayer | two layers of phospholipids are arranged tail to tail |
| transport proteins | their job is to move substances or waste materials through the plasma membrane |
| fluid mosaic model | basis of the plasma membrane |
| cytoplasm | environment inside the plasma membrane; semifluid material. jelly like |
| cytoskeleton | supporting network of long thin protein fibers that form a framework for the cell and provide an anchor for the organelles inside the cells |
| ribosomes | the organelles that help manufacture proteins |
| nucleolus | ribosome production. inside the nucleus |
| endoplasmic reticulum | membrane system. the surface for chemical activity. path way for transporting materials through out the cell. |
| golgi apparatus | flattened stack of membranes that modifies, sorts, and packages proteins into sacs called vesicles.releases the product of the cell |
| vacuole | sac used to store food, enzymes, and other materials |
| lysosomes | vesicles that contain substances that digest excess or worn out organelles and food particles. digestion center. |
| centrioles | organelles made out of microtubules that function during cell division in animal cells only |
| mitochondria | converts food particles into usable energy, powerhouse of cell. |
| chloroplast | organelles that capture light energy and convert it to chemical energy.plant food is made here. |
| cell wall | thick, rigid mesh of fibers that surrounds the outside of the plasma membrane |
| cilia | short numerous projections that look like hairs. used for movement |
| flagella | longer and less numerous than cilia. used for movement |
| diffusion | the next movement of particles from an area where there are many particles of the substance |
| dynamic equilibrium | continuous movement but no overall change |
| facilitated diffusion | uses transport proteins to move other ions and small molecules across the plasma membrane |
| osmosis | diffusion of water across a selectively permeable membrane |
| isotonic solution | a solution having the same osmotic pressure as blood. Iso means equal. |
| hypotonic solution (hypo=under) | any solution with a lower salt concentration than normal body cells so that water flows into the cells by osmosis |
| hypertonic solution (hyper=above) | any solution with a higher salt concentration than normal body cells so that the water is drawn out of the cells by osmosis; |
| active transport | plasma membrane against concentration |
| endocytosis | the process by which a cells surrounds a substance in the outside environment |
