HELLO my fellow classmates. I would just like to say that eighth period biology is da bomb.
Besides that today in class, 13/10, we went over the cycle of a cell. I.P.M.A.T. is the order of the cycle.

The I stands for Interphase. Interphase is where the cell grows and replicates its DNA and centrioles.

The P stands for Prophase. Prophase is where chromatin condenses in to chromosomes, centrioles separate, spindle forms, and the nuclear envelope disappears.

The M stands for Metaphase. Metaphase is where chromosomes line up in the center of the cell, and they attach themselves to the spindle fibers. Also when two chromatin replicate and attach them to each other, it is called sister chromatin.

The A stands for Anaphase. Anaphase is where sister chromatins separate into individual chromosomes and are moved apart.

Last, but not least T for Telophase. Telophase is where chromosomes gather at either end of the cell and two nuclear envelopes will form.

There is also Cytokinesis and that is when the separated cells form new chromosomes, a new cell.
A question in class today, asked by Anthony, was why can't we just have a couple massive cells. Mr. Paek responded by saying, "silly Anthony it is better to have millions of small cells because there is more room for things to go in and out as for big cells there would be barley any movement in and out of the cell."

The class today was only thirty five minutes so we only went over the cycle of a cell and a couple small other things.
Tomorrow in class Mr. Paek will not be here. The homework for tonight is unit packet pages 44-47, and find more info on your cancer that you are researching.
