Prophase
Chromosomes condense, Nucleoli disappear, Mitotic spindle begins to Form, and Centrosomes move away from each other
What are key events of early Prophase?
These are held in the middle by mitotic spindles
What are chromosomes?
The two halves of chromosomes in a cell
What is a sister chromatid?
Something that breaks down
What are mitotic spindles?
Division of the cytoplasm
What is Cytokinesis?
Chromosomes condense further, Nuclear envelope breaks down, Mitotic spindle grows and microtubules enter nuclear area with some attaching kinetochores
What are key events of late prophase?
Centrosomes are at opposite poles, Chromosomes line up at the Metaphase plate
What are the key events of Metaphase?
Paired sister chromatids separate and move to opposite ends of the cell due to the microtubules shortening, cell elongates
What are the key events of Anaphase?
Two daughter nuclei
What is formed?
A cleavage furrow appears due to a contractile ring of actin filaments
What is cytokinesis in animals?
may be represented as a dotted line, dashed line, or not there at all
How is the Nuclear envelope breaking down represented in diagrams?
Microtubules
What is attached to kinetochore?
Sister chromatids split and microtubules are pushing against the nucleus membrane
Why does the cell elongate?
Nuclear envelope delevopes, Nucleoli reappear, chromosomes become less condensed
What are the key events of Telophase?
Vesicles travel to the middle of the cell and form a cell plate
What is cytokinesis in plants?
