Last week we reviewed the process of respiration and we discovered tat it occurs in the mitochondria, uses oxygen and simple sugars (glucose) to produce energy (in the form" of ATP) and produces water and carbon dioxide gas. I asked questions of the group like, "Why do we breath? and "Why do we eat?", in order to see if you could make the connection from breathing and eating to what happens in the mitochondria. We also discovered that without the "powerhouses of the cells", cells would have no way of getting the energy they need to live.
Next, we turned out attention to Mitosis:
Please remember to finish your flip-books and review the stages on the provided notes. Remember IPMAT..(interphase,prophase,metaphase, anaphase, telophase).
Also, think you all for signing my birthday card on Monday. I appreciated the warm wishes.

I read something kinda cool. Scientists theorize that eukaryotes (complex cells like the ones we studied) were formed when a large prokaryote (a simple cell, no nucleus, the genetic material just floats in the cytoplasm) was invaded by two smaller ones (the mitochondria/chloroplasts!) Thatis one interesting symbiotic relationship! Cameron
dear mr.forde,
i resived the flip book homework but i tried to do it but i do not understand it. I dont understand how to do it but can you help me.
Can you help me please
Thank you
Yuliana
Hey Yuliana,
Let's talk tomorrow during class. I"ll be sure to help you with the assignment.
Mr. F :-)
Hey Cam,
You are on the money. (as usual)
It is really fascinating to consider how organisms coexisted before they were incorporated within them as organelles!
Mr. F :-)
i heard that long ago there was this guy who said how creation started. he thought that like tiny cells formed together and then started to function, then when it functioned it would be a heart. there would also be other cells forming together and then that would be the rest of your body.

Hey Steph!
There are many theories out there concerning creation. Although scientists can't be sure, there is a "primordial soup" theory that would match the kind of idea you were expressing. This theory says that at some point all of the conditions for creating life existed in a soup like form billions of years ago.
Se if you can find out more about this.
Mr. Forde :-)
the primordial soup theroy states that about 3.8 billion to 3.55 billion years ago that life began in a warm ocean/pond.
The pond or ocean consists of a combination of chemicals from the atmosphere and some form of energy to make acids, the building blocks of proteins, which would evolve into all the species.

Nicely done...now...there was a scientist that actually tried to simulate this primordial soup in a test tube. He wanted to see if he could make the chemicals necessary for life.
He was a russian scientist named Aleksandr Oparin. maybe you could find out more about his experiments!?
Mr. Forde :-)
Would you like for me to write about a specific experiment like the soup or others he did? Its kind of hard to find something about him too.
Steph S
Hey Steph,
I'm not trying to make you work too hard on this, but maybe a site like this... click here...could help you understand his theory.
Have a nice break from school!
Mr. F :-)
Happy New Years Mr.Forde :]
Hope You had a good Christmas & New Years ! See you in school [ rawwr ]
-Shalimar ♥ -
Happy 2008 Shalimar!
I am looking forward to seeing you all bright and early tomorrow!
Our class has much to accomplish together in '08!
Best wishes to your family in the new year!
Mr. Forde :-)
Whats going to be on the test and what do we have to memorize??
stumbled upon here looking for a good diagram of meiosis, very cool education blog! Great to see enthusiastic teachers and students!
