Today in class we had a sub and she started telling us to get with our groups and start our mitosis labs.Our homework was the pre-lab which was on pages 40, 41, and 42 in our unit packets. The real lab can be found on pages 44-47 which was also in our unit packets.
For the labs, we had to look at onion root tip cells from a microscope and answer the questions according to each phase which were on pages 45-47. These were the descriptions of each phase of the cells:
Interphase: The cell contains easily seen nucleus and nucleolus-chromosomes appear as fine dots within the nucleus.
Prophase: The cell's nucleus is enlarged-nucleolus is no longer visible-chromosomes appear as short strands within the nucleus.
Metaphase: The chromosomes are long and thin strands-they line up along the cell's center and it looks like a "spider on a mirror."
Anaphase: Two sets of separate chromosomes can be seen-they look as if they are being pulled apart from one another.
Telophase: The chromosomes appear at the opposite ends of the cell-the middle of the cell has a line across the center that divides it almost into two new cells.
Daughter Cells: They appear as cells in interphase but smaller and side by side-it's actually the start of a new interphase.
We did the lab for the rest of class. Our homework was to finish the lab if we didn't and to color the picture on page 52A in our unit packet.
P.S: Matt is very flexible.
