This week was all about cells. We read about the discovery of DNA and about resperation vs photosynthosis. We watched a great video about a Ribosome and RNA. It showed how all the organelles work together. All of the organelles seem to need the ribosome or help the ribosome. It also showed how much is cramed in a tiny little cell.
Another video we watched was Yakko's Universe Song. The song tells how everything is made of something smaller. We did this on humans. Atoms makes molucules, and molucules make organelles, organelles make cells, to tissue, tissues make organs, and organs make systems, and all of the systems make a human being. The video helped me understand how small things get. Where if you can't see a cell with a naked eye, then how small is the stuff smaller than a cell.
We have been given the project of thinking of something in life like a city of country that is like a cell. I choose a town because everything inside works together to do things. Also, there are a lot of things that can be compared to cell organelles. A city hall is like the nucleus. Taxes are like the mRNA. Money is like the protiens. A tax office is like a rough E.R and ribosomes are houses and stores. A train station could be like the golgi apperatus. A power plant is like the mitocondria doing resperation. All of these things work together like the organelles of a cell.
