JJ's cell trans./cyc
Chapter 8 Glencoe
| Question | Answer |
|---|---|
| Active transport | requires energy. Movement of molecules against a concentration gradient |
| endocytosis | materials are surrounded by the cell membrane forming a vacuole |
| exocytosis | materials are expelled through the cell membrane |
| facilitated diffusion | passive transport through the cell membrane using transport proteins |
| hypertonic solution | concentration of dissolved substances is higher outside the cell than in. There is more water inside the cell, so water moves out of the cell. |
| hypotonic solution | concentration of dissolved substances is lower outside the cell than in. There is less water inside the cell, so water moves into the cell. |
| isotonic solution | concentration of dissolved substances is the same both inside and outside the cell. |
| osmosis | diffusion of water across a selectively permeable membrane |
| passive transport | cell uses no energy to transport materials across the cell membrane |
| diffusion | movement of molecules from an area of higher concentration to an area of lower concentration. |
| Concentration gradient | the difference in concentration of a substance across time. |
| anaphase | 3rd phase of mitosis. The centromeres split and the chromatid pairs of each chromosome are pulled apart by spindle fibers. |
| cell cycle | continuous cycle of growth and division (interphase and mitosis) |
| centriole | in animal cells. pair of small cylinders like structures that duplicate during interphase and mote to opposite ends of the cell during prophase. |
| centromere | joins 2 sister chromatids of a chromosome |
| chromatin | long strands of DNA in the nucleus. Condenses to form chromosomes |
| chromosome | cell structure that carries the genetic material that is copied and passed from generation to generation of cells. |
| cytokinesis | cell process that follows mitosis. division of cell cytoplasm. |
| interphase | Cell growth phase. Cell increases in size, carries on metabolism, and duplicates chromosomes prior to division. |
| metaphase | 2nd phase of mitosis. very short. Double chromosomes move to the center of the spindle fibers and chromatids are attached by centromeres to a separate spindle fiber |
| mitosis | nuclear cell division. 2 daughter cells are formed, each holding a complete set of chromosomes identical to the parent chromosome |
| organs | group of 2 or more tissues organized to perform complex activities within an organism |
| organ systems | multiple organs that perform a specific function |
| prophase | first and longest phase of mitosis. Chromatin forms into visible chromosomes. |
| sister chromatids | identical halves of a duplicated parent chromosome. Formed during prophase and held together by a centromere. |
| spindle | cell structures that are made of microtubules. Form between the centrioles during prophase; shorten during anaphase pulling apart the sister chromatids. |
| telophase | final phase of mitosis. chromatids reach opposite poles, much of prophase is reversed, chromosomes unwind, spindles break down and the nucleolus reappears along with the nuclear membrane. |
| tissue | groups of cells that work together to perform a specific function |
