About This Simulation
Explore the similarities and differences between bacterial and eukaryotic cell structures. Discover what structural features allow bacteria to survive in extreme environmental conditions.
Learning Objectives
- Describe general bacterial cell structures and their related function
- Compare bacterial organelles to those of eukaryotic cells
- Describe cellular features unique to bacterial cells and relate them to cell survival

Learn More About This Simulation
This short, targeted simulation is adapted from the full-length “Bacterial Cell Structure” simulation.
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.
Compare the outer cell structures
You will start your mission by comparing the outer bacterial cell structure to that of the eukaryotic cell. Explore the similarities and differences between the two cell structures by comparing features such as the cell shapes and the cell walls/membranes. Consider the purpose of the cell wall/membrane and how it helps the survival of the cells.
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?
Compare the bacterial cell structures
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?

For Science Programs Providing a Learning Advantage
North Dakota State College of Science
“They did the simulation at home, then completed the in-person lab within 30 minutes, no questions asked, and passed the quiz with flying colors.”
Lecturer in Human Physiology
University of Westminster
"I saw some of the students who clearly didn’t necessarily like sitting there reading a book discover they could turn on Labster and keep up with the rest of the class because it spoke to them.
Modesto City Schools
"Having something that's engaging for the students gives teachers that opportunity to breathe and get excited again. Because they're seeing the kids light up, they're seeing the kids engage with content."
Wenatchee Valley College
"The question always is, ‘Can we demonstrate that the students are meeting course outcomes?’ Check! We can do that.”
San José State University
"We surveyed over 400 students. More than 90% thought Labster was easy to navigate, and that it was fun, but more importantly, most of them felt confident that they could execute the labs in person. And that confidence is a big deal."

A Labster virtual lab is an interactive, multimedia assignment that students access right from their computers. Many Labster virtual labs prepare students for success in college by introducing foundational knowledge using multimedia visualizations that make it easier to understand complex concepts. Other Labster virtual labs prepare learners for careers in STEM labs by giving them realistic practice on lab techniques and procedures.
Labster’s virtual lab simulations are created by scientists and designed to maximize engagement and interactivity. Unlike watching a video or reading a textbook, Labster virtual labs are interactive. To make progress, students must think critically and solve a real-world problem. We believe that learning by doing makes STEM stick.
Yes, Labster is compatible with all major LMS (Learning Management Systems) including Blackboard, Canvas, D2L, Moodle, and many others. Students can access Labster like any other assignment. If your institution does not choose an LMS integration, students will log into Labster’s Course Manager once they have an account created. Your institution will decide which is the best access method.
Labster is available for purchase by instructors, faculty, and administrators at education institutions. Purchasing our starter package, Labster Explorer, can be done using a credit card if you are located in the USA, Canada, or Mexico. If you are outside of North America or are choosing a higher plan, please speak with a Labster sales representative. Compare plans.
Labster supports a wide range of STEM courses at the high school, college, and university level across fields in biology, chemistry, physics, and health sciences. You can identify topics for your courses by searching our Content Catalog.
