Question

The stages of mitosis were originally defined by cellular features observable through a light microscope. the six micrographs below show animal cells (lung cells from a newt) during the five stages of mitosis, plus cytokinesis. (note that interphase is not represented in these micrographs.) in these images, the chromosomes have been stained blue, microtubules green, and microfilaments red.

Step-by-step explanation:

What occurs in each stage/What you should be looking for:

1) prophase: spindles begin to form + centrosomes begin to move apart

2) prometaphase: spindle fibres penetrate nuclear region + centrosomes = on opposite sides of nucleus

3) metaphase: chromosomes align along the metaphase plate

4) anaphase: sister chromatids separate + cell elongates b/w poles

5) telophase: chromosomes begin de-condensing + nuclear envelops begin to form

6) cytokinesis: two separate daughter cells form
