| Question | Answer |
|---|---|
| ATP | energy-carrying molecule that cells use to power their metabolic processes |
| cell wall | rigid layer that surrounds the plasma membrane of a plant cell and helps support and protect the cell |
| central vacuole | large saclike organelle in plant cells that stores substances such as water and helps keep plant tissues rigid |
| chloroplast | organelle in the cells of plants and algae where photosynthesis takes place |
| cytoskeleton | structure of filaments and tubules in the cytoplasm that provides a cell with an internal framework |
| endosymbiotic theory | theory that eukaryotic organelles such as mitochondria evolved from ancient, free-living prokaryotes that invaded primitive eukaryotic cells |
| golgi apparatus | organelle in eukaryotic cells that processes proteins and prepares them for use both inside |
| mitochodria | organelle in eukaryotic cells that makes energy available to the cell in the form |
| phospholiquid bilayer | double layer of phospholipid molecules that makes up a plasma membrane |
| vacuole | large saclike organelle that stores and transports materials inside a cell |
| vesicle | large saclike organelle that stores and transports materials inside a cell |
| active transport | movement of substances across a plasma membrane that requires energy |
| diffusion | type of passive transport that does not require the help of transport proteins |
| endocytosis | type of vesicle transport that moves substances into a cell |
| exocytosis | type of vesicle transport that moves substances out of a cell |
| facilitated diffusion | diffusion with the help of transport proteins |
| osmosis | diffusion of water molecules across a membrane |
| passive transport | movement of substances across a plasma membrane that does not require energy |
| sodium-potassium pump | sodium-potassium pump type of active transport in which sodium ions are pumped out of the cell and potassium ions are pumped into the cell with the help of a carrier protein and energy from ATP |
| transport protein | protein in a plasma membrane that helps other substances cross the membrane |
| vesicle transport | type of active transport in which substances are carried across the cell membrane by vesicles |
