Overview:
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?
- How did
Eukaryotic cells
likely come about?
Please depict the
process below?
The _________________ Theory:
Which organelles were a result of this process?
Prokaryotes vs. Eukaryotes:
What are the 3 Domains of life: (Circle the Prokaryotic Domain(s).)
1.
2.

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