Microorganisms on the Move. There are more than 50,000 different types of microorganisms known to scientists -– and they discover more every year. Biophysicist Zvonimir Dogic and his research group at Brandeis University are interested in the rules that govern the ways that materials assemble themselves. The researchers have been studying the spontaneous waving of flagella and cilia, which enables microorganisms to move.
In this activity, students will learn how to prepare deep well slides for observing two types of microorganisms called Paramecium (a group of protozoa, or single-celled organisms, which move with cilia, so they are called “ciliates”) and Euglena (microorganisms which move with flagella, so they are known as “flagellates”). Students will observe these microorganisms through a microscope, and compare and contrast the physical characteristics of each type of microorganism. Vocabulary Cilia: a group of hair-like structures that assist organisms with locomotion. What’s Happening? Johnson Explorations - Cell Size.
