Protists Bacteria Archea
Archaeans include inhabitants of some of the most extreme environments on the planet.

Archaea also thrive in mud and they are one reason it is usually smelly.
Types of Archaea
Archea are prokaryotes, meaning.
Archea are prokaryotes, meaning.no nucleus!
Types of Archaea Methanogens: Ones that produce methane gas as a waste product of their digestion.
Types of Archaea Methanogens: Ones that produce methane gas as a waste product of their digestion. Halophiles: Ones that live in salty environments.

Types of Archaea Methanogens: Ones that produce methane gas as a waste product of their digestion. Halophiles: Ones that live in salty environments. Thermophiles: They live at extremely hot temperatures. Psychrophiles: Those that live at unusually cold temperatures.
Archea are rather pretty in large numbers
Bacteria are composed of microorganisms that are much more common than Archaea and live almost anywhere.

The oxygen atmosphere that we depend on was generated by numerous cyanobacteria during the Archaean and Proterozoic Eras.
The oxygen atmosphere that we depend on was generated by numerous cyanobacteria during the Archaean and Proterozoic Eras. Before that time, the atmosphere had a very different chemistry, unsuitable for life as we know it today.
Cyanobacteria gave rise to the origin of plants.
Cyanobacteria gave rise to the origin of plants. The chloroplast that helps plants make food from the sun is a cyanobacterium living within the plant's cells.

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.
