Chapter 6.2 - Mitosis

Question 1

Prophase

Answer 1

Chromatin fibres coil and condense to form chromosomes
Nucleolus disappears
Nuclear envelope disintegrates
Microtubules form spindles linking poles of
Centrioles move to poles for spindle formation

Question 2

Metaphase

Answer 2

Spindle fibres move chromosomes into metaphase plate

Question 3

Anaphase

Answer 3

Centromeres divide.
Spindle fibres shorten
Chromatids pulled to opposite poles

Question 4

Telophase

Answer 4

Chromatids are now chromosomes
Nuclear envelope forms
Chromosomes uncoil - nucleolus
Cytokinesis

Question 5

Cytokinesis

Answer 5

Cleavage furrow

Cytoskeleton pulls membrane in until it fuses

Question 6

Plant cell cytokinesis

Answer 6

Vesicles from Golgi apparatus line up on metaphase plate, fuse together and with the membrane
Cell wall forms along new sections
