9.6 - Meiosis under a microscope

Question 1

Summary of events under a microscope

Answer 1

Question 2

How to distinguish cytokinesis

Answer 2

cytoplasm is dividing and 4 haploid cells are forming

Question 3

How to distinguish telophase II?

Answer 3

nuclei are forming around the 4 groups of condensed chromosomes

Question 4

Anaphase II - how to distinguish it

Answer 4

centromeres divide and chromatids are being pulled to opposite poles

Question 5

How to distinguish metaphase II

Answer 5

single whole chromosomes are lined up along the equator of the spindle in single file

Question 6

How to distinguish prophase II?

Answer 6

single whole chromosomes are visible

Question 7

how to distinguish cytokinesis

Answer 7

cytoplasm is dividing and the cell membrane is pinching inwards to form 2 cells

Question 8

how to distinguish telophase I

Answer 8

there are 2 groups of condensed chromosomes around which nuclei membranes are forming

Question 9

how to distinguish anaphase I

Answer 9

• whole chromosomes are being pulled to opposite poles with centromeres intact

Question 10

How to distinguish metaphase I

Answer 10

homologous pairs are lined up side by side along the equator of the spindle

Question 11

How to distinguish Prophase I

Answer 11

the homologous pairs of chromosomes are visible

Question 12

How can Meiosis I and Meiosis II be identified under a microscope?

Answer 12

1. homologous chromsomes line up side by side in meiosis I only
2. if the pair of chromosomes are existent then meiosis is occurring!
   * meiosis I has 2 new cells
   * meiosis II has 4 new cells
