Topic 2- Recognising stages in mitosis

Question 1

How can you recognise prophase

Answer 1

-Chromosomes are visible
-The nuclear envelope is breaking down

Question 2

How can you recognise metaphase?

Answer 2

-Chromosomes are lined up along the middle of the cell

Question 3

How can you recognise anaphase?

Answer 3

Chromosomes are moving away from the middle of the cell, towards opposite poles

Question 4

How can you recognise telophase?

Answer 4

-Chromosomes have arrived at opposite poles of the cell
-Chromosomes begin to decondense
-The nuclear envelope is reforming

Question 5

How can you recognise cytokinesis in both animal and plant cells?

Answer 5

-Plant cells: a cell plate forms at the site of the metaphase plate and expands towards the cell wall of the parent cell, separating the daughter cells
-Animal cells: a cleavage furrow forms and separates the daughter cells
