An interactive module where students take a closer look at cells and relate their structure to function. They also discover how cell organelles work in systems to maintain important biological processes and how cells communicate.

Make learning about cells fun and easy with a collection of short video clips about cellular biology. Find out about the structure and function of the main organelles inside an animal cell.

Take this interactive, multiple-choice quiz over cells and cell structure, then review your score and any missed questions at the end.

In this third unit of a Biology course, students learn about cells and cell structure. They compare prokaryotic and eukaryotic cells and learn about the specialized structures in a cell and what their functions are. They will also learn...

Explanation of when the cell was discovered and how ideas have evolved into modern cell theory. Discover the cell structures and their functions.

Overview of mitosis and the cell structures that are critical to the process.

This comprehensive study guide covers the main terms and concepts needed for a unit on cell division and the cell life cycle.

Learners learn the characteristics that comprise a filter, and then use their computational thinking skills to design their own filters. The goal is to ultimately learn how these filters are related to many biological processes.

This interactive website about microscopes and microbes provides students with an introduction to cellular biology.

Two multiple-choice quizzes about cells. The first is on cell theory, basic information about cells, and cell types. The second is on cell structures and functions.
