Cells are the fundamental unit of all living things. Cells are composed of a variety of organelles that underlie the structure and function of the cell. In this experience we will complete a brief overview of cell theory and look at the basics of how we study cells.StandardsBIO.A.1.2.2 Describe and interpret relationships between structure and function at various levels of biological organization (i.e., organelles, cells, tissues, organs, organ systems, and multicellular organisms).

Host Harry Kreisler welcomes biophysicist Chikashi Toyoshima for a discussion of his remarkable achievement in capturing the first images of cellular activity as the calcium ion pump makes possible the contraction and relaxation of muscle tissue on a signal from the brain. Topics covered include: how structure determines process in cellular activity, the technical innovations required for this breakthrough in the biosciences, and why visualization is so important in understanding cellular processes. He also reflects on creativity in science and how the images he captured affected his understanding of humankind's place in the universe. (52 minutes)

Eukaryotic cells are the foundation of our human body. They help us produce energy, grow, move, and carry out all our life functions. Looking at these cells, the learner will be challenged to explain how they help us grow and function. Eukaryotic cells are unique in the cellular world because they have membrane bound organelles. For this lesson experience, the learner will explore eukaryotic cell structure and function. Additionally they will travel through models of the cells, drawing comparisons with life functions at the micro and macro level.StandardsBIO.A.1.2.1 Compare cellular structures and their functions in prokaryotic and eukaryotic cells

In this project, you will explore a real-world problem, and then work through a series of steps to analyze that problem, research ways the problem could be solved, then propose a possible solution to that problem. Often, there are no specific right or wrong solutions, but sometimes one particular solution may be better than others. The key is making sure you fully understand the problem, have researched some possible solutions, and have proposed the solution that you can support with information / evidence.Begin by reading the problem statement in Step 1. Take the time to review all the information provided in the statement, including exploring the websites, videos and / or articles that are linked. Then work on steps 2 through 8 to complete this problem-based learning experience.

Cells are the fundamental unit of all living things; however, there are many different types of cells. Students often look at the world with a concrete, inflexible view, knowing only what they see with their eyes. Life is diverse and different, and you will be challenged as you investigate life that is different from you. For this experience, we focus on one of the two major divisions of cells called Prokaryotic Cells. These cells are considered primitive compared to the cells that make up humans. Learners will explore various types of prokaryotic cells and reflect on how they relate to their cell functions.StandardsBIO.A.1.2.1 Compare cellular structures and their functions in prokaryotic and eukaryotic cells
