Mitosis

Question 1

Prophase

Answer 1

-The nuclear envelope fragments separate so the chromosomes can separate, the
-centrosomes move to opposite poles of the cell and spindle fibers begin to form
-chromatin condenses to form chromosomes

Question 2

Metaphase

Answer 2

• the chromosomes line up in single file in middle of cell
  -the spindle fibers attach to the chromosomes at the kinetochore (centromere region)

Question 3

Anaphase

Answer 3

-the cell starts stretching and the spindle fibers (microtubules) start shortening
-the sister chromatids are pulled apart
(for a brief period there are double the amount of chromosomes in each cell)

Question 4

Telophase

Answer 4

two nuclear envelopes reform, in which the chromosomes uncoil into chromatin
-the cell membrane begins to pinch
-spindles disintigrate

Question 5

Cytokinesis

Answer 5

the cytoplasm itself splits, forming two daughter cells

Question 6

4 stages of mitosis

Answer 6

PMAT, Prophase, metaphase, Anaphase, Telophase

Question 7

difference in cytokinesis with animals and plants

Answer 7

in animal cells, the membrane pinches in the center until seperated to form its daughter cells.
in plant its different bc of plant wall so it forms a cell plate (in between the 2 nuclei) which actually divides the cell in 2
