Cell Cycle

Question 1

Explain prophase

Answer 1

-the longest phase
-chromatin condenses
-nucleolus disappears
-DNA coils tightly into sister chromatids
- opposite ends of spindle fibres connect to the centromeres

Question 2

Explain Metaphase

Answer 2

-chromosomes line up in the middle of the cell

Question 3

Explain anaphase

Answer 3

• The spindle fibres separate the sister chromatids
  -The chromosomes move to opposite ends of the cell

Question 4

Explain telophase

Answer 4

-nuclear membrane forms around each set of chromosomes
-chromosomes spread out into chromatin
-nucleolus becomes visible again

Question 5

Explain Cytokinesis (animal cell)

Answer 5

• Inside of the cell pinches the cytoplasm until two identical daughter cells form

Question 5

Explain Cytokenisis (plant cell)

Answer 5

-cell plate forms to separate the cells into daughter cells
-new cell walls form
