Prokaryotes and Eukaryotes
School meeting share, february 11, 2016
4th and 5th graders
Hi, I found out that all living things fall into two classifications of cell types: Prokaryotic cells and Eukaryotic cells.
Hi, I found out that pseudopodia mean “false feet.”
Hi, I was surprised that a bacterial cell could have a tail! It’s called the flagellum.
Hi, I found out that a Eukaryote is an organism with a complex cell.
Hi, I was surprised by how bacteria transmit their DNA into a host.
When we started our simulation on The Age of Discovery, we learned about some of the different diseases that the early explorers could have suffered from. One of the diseases was called dysentery. We learned about the different microorganisms that cause dysentery. Dysentary is a disease caused by contaminated food and water. One organism that causes dysentary is a rod-shaped bacteria called, Shigella and another is a blob shaped organism with pseudopodia, called Entamoeba. Learning about the bacteria and amoeba that cause dysentery made us want to learn about the structure of Prokaryotic and Eukaryotic cells.
We played a game to help us learn about the anatomy of a cell. We made our own illustrations and we made our own clay models. We decided to write a textbook paragraph to compare the differences between the two cell types. We learned that Prokaryotic cells (found in bacteria and archaea) do not have membrane bound nuclei and do not have membrane-bound organelles. Prokaryotes tend to be single-celled organisms with their genetic material in a single circular coiled loop. “Pro” means before and “karyote” means nucleus. Eukaryotic organisms are generally larger and have specialized organelles. Eukaryotes include animals, plants, fungi, protists and are generally multicellular organisms. “Eu” means true and “karyote” means nucleus, they have a membrane-bound nucleus that contains DNA in linear chromosomes.
