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 |
