Kingdoms, Domains and Cells & Endosymbiotic Theory

What are the three domains of life?

Bacteria, Archaea, and Eukarya.

Name the six kingdoms.

Eubacteria, Archaea, Protista, Fungi, Plantae, Animalia.

Which kingdoms belong to the domain Eukarya?

Protista, Fungi, Plantae, and Animalia.

History of?

Reflects a deeper understanding of evolutionary relationships based on molecular evidence.

Prokaryote

"Before Nucleus"

Small and Simple

Lack organelles

Single-celled

Single circular chromosome

Eukaryotic

"True Nucleus"

Evolved from Prokaryotes

Larger and more complex

Contain nucleus

Contain organelles

Single-celled or multicellular

Multiple linear chromosomes

What's the main difference between prokaryotic and eukaryotic cells?

Eukaryotic cells have a nucleus and organelles; prokaryotic cells do not.

What does the endosymbiotic theory explain?

That some eukaryotic organelles, such as mitochondria and chloroplasts, were once free-living prokaryotes that were engulfed by other cells, and formed a mutually beneficial symbiotic relationship

What evidence supports the endosymbiotic theory?

They have their own DNA, double membranes, and reproduce like bacteria.
