Overview:

Cellular Live-Oxygen Revolution-Nucleated Cells-MulitcellularityCambrian Explosion

How did Eukaryotic cells come about: endosymbiosis 0 o -> Co -> O

The ____endosymbiont_____________ Theory: a result of this process? Eukaryotic cells

1. Label the 5 parts of the timeline presented by Dr. Biederman. - What organisms existed 3.5 billion years ago? What is their importance? What would these organisms likely look like under a microscope?

Which organelles were

Prokaryotes vs. Eukaryotes: What are the 3 Domains of life: (Circle the Prokaryotic Domain(s).) 1.Eukaryote

2.Bacteria

3. Archaea

Contrast: (Think about- DNA, Reproduction, organelles, size, motility, histone proteins, and examples of organisms from class)

Prokaryote Cells

Eukaryote Cells

Review: Compare and Contrast: Which domain does this apply to? How do you know? bacteria Gram (+) Gram (-)

How can you help stop the spread of antibiotic resistance genes?

Can a bacterial species be both good and bad for human health? How else do we benefit from bacteria? Yes, if a strand is pathogenic that doesn’t mean all of its species are harmful. Microbiome.

Protists: What are common features of all/most protists? (Think about which domain they are in? Lifestyle?) Eukaryotes

Reproduction: Prokaryote

Eukaryote

Processes Involved Resulting Cells

Benefits

What type of cell division is used for Eukaryotic tissue growth? Which process is this similar to and why? How can Prokaryotes get genetic diversity?

Fungi: Are fungi more closely related to animals or plants? How do they obtain food? What is the significance of this?

Cell Wall Composition:

Describe the function of each structure and label on the image. Hyphae-

Structure:

Look at your notes. Determine what is MOST relevant and distinguishable about each phyla. (12 things each) Chytridiomycota -aquatic -kills sea life

Glomeromycota -90% of plants

Zygomycota

Basidiomycota

Ascomycota

What are some symbiotic relationships from the groups above? How does each side benefit?...
