Question
Why are you more likely to see a polar view in animal cells than in plant cells?
Hi Regina: Thanks for your question.
I'm assuming that you're looking at onion root tip and fish blastula for your mitosis exercises (at least, that's what we use). The onion (plant) is growing in a single dimension - down, so you see all the phases oriented in one plane. The fish blastula is a ball of cells, so the mitoses are in three dimensions. You will see the cells from the top, bottom, sides and in between.
Because the plants are oriented in an up-down direction, you see them from the sides. The fish are oriented in all directions, so you see polar as well as equatorial views.
Hope this helps!
