Vocab Module 6
Module 6 Vocab Exploring Creation with Biology
| Question | Answer |
|---|---|
| Absorption | Transport of dissolved substances into cells |
| Digestion | Breakdown of absorbed substances |
| Respiration | Breakdown of food molecules with a release of energy |
| Excretion | Removal of soluble waste materials |
| Egestion | Removal of nonsoluble waste materials |
| Secretion | Release of biosynthesized substances |
| Homeostasis | Maintaining the status quo |
| Reproduction | Producing more cells |
| Cytology | Study of cells |
| Cell wall | Rigid structure on the outside of certain cells, usually plant and bacteria cells |
| Middle lamella | Thin film between the cell walls of adjacent plant cells |
| Plasma membrane | Semipermeable membrane between the cell contents and either the cell wall or the cell's surroundings |
| Cytoplasm | Jellylike fluid inside the cell in which the organelles are suspended |
| Ions | Substances in which at least one atom has an imbalance of protons and electrons |
| Cytoplasmic streaming | Motion of cytoplasm in a cell that results in a coordinated movement of the cell's contents |
| Mitochondria | Organelles in which nutrients are converted to energy |
| Lysosome | Organelle in animal cells responsible for hydrolysis reactions that break down proteins, polysaccharides, disaccharides, and some lipids |
| Ribosomes | Non-membrane bound organelles responsible for protein synthesis |
| Endoplasmic reticulum | Organelle composed of an extensive network of folded membranes that performs several tasks within a cell |
| Rough ER | ER that is dotted with ribosomes |
| Smooth ER | ER that has no ribosomes |
| Golgi bodies | Organelles in which proteins and lipids are stored and then modified to suit the needs of the cell |
| Leucoplasts | Organelles that store starches or oils |
| Chromoplasts | Organelles that contain pigments used in photosynthesis |
| Central vacuole | Large vacuole that rests at the center of most plant cells and is filled with a solution that contains a high concentration of solutes |
| Waste vacuoles | Vacuoles that contain the waste products of digestion |
| Phagocytosis | Process by which a cell engulfs foreign substances or other cells |
| Phagocytic vacuole | Vacuole that holds the matter which a cell engulfs |
| Secretion vesicle | Vesicle that holds secretion products so that they can be transported to the plasma membrane and released |
| Pinocytic vesicle | Vesicle formed at the plasma membrane to allow the absorption of large molecules |
| Microtubules | Spiral strands of protein molecules that form a tubelike structure |
| Nuclear membrane | Highly-porous membrane that separates the nucleus from the cytoplasm |
| Chromatin | Clusters of DNA, RNA, and proteins in the nucleus of a cell |
| Cytoskeleton | Network of fibers that holds the cell together, helps the cell to keep its shape, and aids in movement |
| Microfilaments | Fine, threadlike proteins found in the cell's cytoskeleton |
| Intermediate filaments | Theadlike proteins in the cell's cytoskeleton that are roughly twice as thick as microfilaments |
| Phospholipid | Lipid in which one of the fatty acid molecules has been replaced by a molecule that contains a phosphate group |
| Passive transport | Movement of molecules through the plasma membrane according to the dictates of osmosis or diffusion |
| Active transport | Movement of molecules through the plasma membrane (typically opposite the dictates of osmosis or diffusion) aided by a process that requires energy |
| Isotonic solution | Solution in which the concentration of solutes is essentially equal to that of the cell that resides in the solution |
| Hypertonic solution | Solution in which the concentration of solutes is greater than that of the cell that resides in the solution |
| Plasmolysis | Collapse of a walled cell's cytoplasm due to a lack of water |
| Cytolysis | Rupturing of a cell due to excess internal pressure |
| Hypotonic solution | Solution in which the concentration of solutes is less than that of the cell which resides in the solution |
| Activation energy | Energy necessary to get a chemical reaction going |
