Twico

These are our diagrams showing Mitosis and Meiosis.


The Animal
Mitosis is when cells devide and it is split into these steps: Interphase, Prophase, Metaphase, Anaphase, and Telophase.
Meiosis is when sex cells divide so the right amount of single chromosomes are left after Meiosis.
This photo explains the process of meiosis.


This photo explains the series of mitosis.

Mitosis makes new cells that are just the same as the parent cells and meiosis makes new egg and sperm cells,(half).

Mitosis/ Meiosis


This is a diagram of Meiosis in an Iotis.
This is the diagram of Mitosis happening in an Iotis.
These diagrams were made by Braden and Shannon on SMART notebook.

This is a Mitosis Diagram.
This is from the chromosomes of Expo the Lizard. (made-up)




This is a Meiosis Diagram.
It is also from Expo the Lizard. (made-up)

today in science we took notes for 50 minutes

today we learned about flipping the images up to down and left to right

Telophase
the cells are splitting and the nuclear membranes are back.

Prophase


http://www.edupic.net/cells.htm
You can see that it is in prophase because the chromosomes are shortening and thickening.

This is TELOPHASE and I know that because the chromosomes just spilt.
This is a picture of second half of middle prophase. We can tell this is a picture of prophase because it shows centrosomes moving to their opposite sides.

I know this picture is metaphase because you can see the chromosomes splitting apart.
anaphase, you can see that its in anaphase because you can see the cells splitting

Telophase Cell

Below is a picture of a cell in the middle of the last stage... telophase. I know this is a picture of telophase because the cell is in the middle of cytokinisis.

i know this is it because it lines up chromosomes

Anaphase is when the chromosome pairs split and there is a roughly even distribution of the non-genetic cellular material.

This picture shows the metaphase step because in the metaphase step it shows the chromosones all lined up. I got this from creativecommons.com

Prophase

I know this picture is right becuase it shows how the membrane is dissolving.

metaphase
lined up chromosomes
I know this picture is telophase because is shows the cells splitting up.
