Objective: Through observing protist from pond water students will see how single cell organisms are organized and how they carry out specific functions?
Materials: different samples of pond water, droppers, slides, light microscopes,
In this lab you will be asked to prepare a slide of pond water and locate protist. To help you find protest easier you can use the low power at first to find them, and then make observations under high power. These organisms may swim fast and make it difficult for them to find. To make it easier you can place some food in your slide to attract them or use thread to corral them. Once you find a protist you will have to use the provided key to identify them.
Make a slide of pond water.
Locate two protist.
Make a drawing of each protist and write down your observations.
Identify the three protist you found using the key provide to you in class.
Repeat the above steps for the three samples of pond water. Be sure to find different protist to observe.
Do these single celled organisms have individual tissues? Or organs?
How do you think these single celled organisms carry out life’s functions (example, circulation, digestion, reproduction, etc.) explain?
Are these single celled organisms organized? Explain your answer
