Cell Growth/develope
Cell Growth and developement, mitosis, cytokinesis, interphase ms. geiger bio
| Question | Answer |
|---|---|
| driven by kinetic energy of the molecules | diffusion, osmosis |
| driven by hydrostatic (fluid) pressure | filtration |
| provides for cellular uptake of solids or large particles from cell exterior | endocytosis, phagoytosis |
| nucleus deviding | mitosis |
| cytoplasm dividing | cytokinesis |
| chromosomes contain what? | genetic information and protein |
| transports amino acids, sugars and Na+ thru plasma membrane | solute pumping |
| DNA that isn't condensed,(unwound chromosomes) | Chromatin |
| moves thru a semipermeable membrane | diffusion, osmosis |
| A means of secreting cell products | exocytosis |
| proceeds against a conc. gradient; requires a carrier | nsolute pumping |
| follows a conc. gradient | simple diffusion, osmosis |
| The spindle forms through the migration of the centrioles | prophase |
| Period of divisioin | mitosis |
| actual division | cytokinesis |
| chromosomal material replicates | none |
| Period between cell division | Interphase |
| A cleavage furrow forms during this phase | telophase |
| chromosomes attach to the spindle fibers | prophase |
| the nuclear membrane is absent during the entire phase | anaphase + metaphase |
| The nucleus makes | mRNA |
| chromosomes first appear to be duplex structures | prophase |
| the nucleoli and nuclear membrane disappear | prophase |
| period during which a cell carries out its usual metabolic activites | none |
| What is the longest stage of mitosis? | prophase |
| What happens in Prophase | Centrioles move to opposite poles, chromosomes attach to spindle fibers, nucleur envelope disapears, nucleolus disappears |
| what 2 things disapear in prophase? | the nucleolus and the nucleur envelope |
| What is the shortest stage of mitosis? | metaphase |
| What happens in metaphase? | chromosomes line up along the middle of the cell, spindle fibers connected to centrioles |
| What do the spindles form | asters |
| require ATP (cellular energy) | endocytosis, phagocytosis, + excocytosis + filtration |
| What happens during anaphase? | sister chromatids rip apart |
| when chromosomes cease their poleward mov't, this phase begins | telophase |
| what happens during telophase? | chromosomes uncoil, nucleur envelope reforms, nucleolus reform, spindles break apart |
| What 2 things reform during telophase? | nucleolus and the nucleur envelope |
| what is the division of the cytoplasm called | cytokinesis |
| Duringcytokinesis animal cells ___ | pinch |
| chromosomes align on the equator of the spindle | metaphase |
| spindles break apart during what stage of mitosis | telophase |
| sister chromatids rip apart during what stage of mitosis? | anapphase |
| The nuclear membrane and nucleoli reappear | telophase |
| centromeres break, and chromosomes begin migration toward opposite poles of the cell | anaphase |
| chromatin coils and condenses to form deeply staining bodies | prophase |
