Presentation transcript:

The Kingdom of Protista This section explains what protists are.

What is a Protist? What Is a Protist? It is any organism that is not a plant, an animal, a fungus, or a prokaryote.

What Is a Protist? Circle the letter of each sentence that is true about protists. All cells have a nucleus. All cells have membrane-bound organelles.

What Is a Protist? Why are some organisms that consist of thousands of cells considered to be protists? They are considered protists because they are so similar to others that are truly unicellular.

Evolution of Protists The first eukaryotic organisms on Earth were____. Protists

Evolution of Protists What is biologist Lynn Margulis’s hypothesis about where the first protists came from?

The first eukaryotic cells may have evolved from a symbiosis of several cells. Mitochondria and chloroplasts found in eukaryotic cells may be descended from aerobic and photosynthetic prokaryotes that began to live inside larger cells.

Classification of Protists Complete the table about protist classification. GROUPS OF PROTISTS Group Method of Obtaining Food Animal like protists Consume other organisms Plant like protists Produce their own food by photosynthesis Fungus like protists Obtain food by external digestion, either as decomposers or parasites

Classification of Protists What don’t categories of protists based on the way they obtain food reflect about these organisms? They don’t reflect their evolutionary history.
