Unicellular organisms living in water
Deconstruct a question
Consider the questions, “How do unicellular organisms living in water control the entry/exit of water from their cells? Are they able to live in any
environment? How could this be tested?”
Explore the various factors that would be involved in how unicellular organisms control the entry/exit of water, and research if the control of these factors
would enable these types of organisms to live in any environment. Make informed decisions about which unicellular organisms might be able to be used to
determine experimentally how one factor might affect the ability of this organism to live in a particular environment. Explore the risk factors and ethical
considerations of doing an experiment with live organisms. Develop a method to test your factor. This experiment will not be performed.
