This flashcard details the stages of mitosis (Prophase, Metaphase, Anaphase, Telophase) and cytokinesis in both animal and plant cells. It includes descriptions of key events and accompanying images for visual understanding.
Tento soubor obsahuje informace o procesech mitózy, včetně profáze, metafáze, anafáze a telofáze, a také o cytokinezi u živočišných a rostlinných buněk. Součástí jsou popisy klíčových událostí a obrázky pro vizualizaci.
| Front | Mitosis process 2.1.6(b)and(d) |
|---|---|
| Back | Prophase - nucleolus and nuclear envelope disappear and nuclear membrane breaks down - centrioles on opposite poles - spindle fibres attach to centromeres and moves chromosomes to equator Metaphase - chromosomes moved by spindle fibres to form metaphase plate at equator Anaphase - centromeres divide so chromatids separated and pulled to opp poles by shortening spindle fibres Telophase - chromatids (now chromosomes) reach poles where they assemble, and nuclear envelope reforms - chromosomes start to uncoil and nucleolus formed Cytokinesis (animal cells) - cleavage furrow forms around equator, membrane pulled inwards by cytoskeleton (until close enough to fuse around equator, forming 2 daughter cells) (in plant cells) - have cell walls so can’t form cleavage furrow, vesicles (from golgi) assemble at equator, where they fuse with eachother and membrane to divide cell into 2 - cell wall forms along new section of membrane |
