Comparing Bacterial Structures

该简短的靶向模拟是根据全长的“细菌细胞结构”模拟所改编的。

Global warming is causing the ice to melt in Antarctica, leading to the discovery of bacteria that have survived this extreme environment. In this simulation, you will learn about bacterial cell structures and how these are important for bacterial survival. Discover which structural features have allowed the antarctica bacteria to survive in the extreme conditions.

比较外部细胞结构

您将通过将外细菌细胞结构与真核细胞的外部细胞结构进行比较来开始任务。通过比较细胞形状和细胞壁/膜等特征，探索两个细胞结构之间的相似性和差异。考虑细胞壁/膜的目的及其如何帮助细胞的存活。

Assemble the inner cell structures

Assemble the cytoplasmic content of the bacterial and the eukaryotic cell. Look at the names of each organelle or cellular component and decide which cell you should place them in. Get feedback about your decisions, and try again if you placed a component incorrectly. Compare the different components in the two cells, such as the nucleus and nucleoid. Can you place all the components in the cells correctly?

比较细菌细胞结构

Finally, you will compare your bacterial cell structures to other bacteria and learn which cellular structures are important for the bacteria to survive in extreme environments. Study the structures of E. coli, coccus bacterium, and vibrio bacteria. Learn the function of each component. Can you help the Arctic researchers decide which features aid the survival of the bacteria?
