cell division- mitosis

Question 1

mitosis order

Answer 1

prophase, metaphase, anaphase, telophase

Question 2

prophase

Answer 2

-chromosomes get short, fat and visible
-each chromosome appears as sister chromatids
-nuclear membrane begins disappear
-fibres appear in the cytoplasm
-centrioles migrate to poles

Question 3

metaphase

Answer 3

-the sister chromatids attach to the spindle fibers with their centromeres
-they lie along equator

Question 4

anaphase

Answer 4

-the centriole contracts pulling spindle fibers
-sister chromatids separate
-chromosomes migrate towards the poles

Question 5

telophase

Answer 5

-chromosomes reach poles and form a compact group
-new nuclear membrane reforms
-spindle breaks down
-cytoplasm divides
=animal cells form a construction, cleavage furrow
=plant cells form cell plate, middle lamella?
