Protists are like the junk drawer of eukaryotes.
Protists are like the junk drawer of eukaryotes. If it s not a plant, animal, fungus, or bacteria it just goes in the kingdom Protista.
Protist: An organism with a single eukaryotic cell or colonies of cells, lacking tissues, and eats, makes, or decomposes for food. Copyright 2010 Ryan P. Murphy
Remember, Protists lack tissues. Which specimen below is a protist, and which is an animal? Copyright 2010 Ryan P. Murphy
Answer! Protists do not have eyes because an eye is made of tissue. Copyright 2010 Ryan P. Murphy
Note: Some protists such as the Euglena have a sensitive organelle called an eye spot to detect light. It s not a true eye.
Which specimen below is a protist, and which is an animal? Copyright 2010 Ryan P. Murphy
Answer A. Protista do not have tissues so they cannot have a heart. Copyright 2010 Ryan P. Murphy
Is this a protist? Why or why not? Copyright 2010 Ryan P. Murphy
Answer! No, because the specimen has tissues such as eyes, and some sort of digestive tract.
