Endosymbiosis

Endosymbiotic Theory is the idea that ______ cells could have evolved from_____cells

• prokaryotic, eukaryotic

• eukaryotic, animal

• prokaryotic, plant

• eukaryotic, prokaryotic

Prokaryotic cells do not have

• cell wall

• nucleus

• cytoplasm

• ribosomes

Both prokaryote and eukaryotes have a cell membrane

• True

• False

• Only eukaryotes have a membrane

• Only prokaryotes have a membrane

Symbiosis means

• Feeding off of something

• Using something for its ATP

• Living in harmony

• Producing sugars

Evidence for endosymbiosis includes

• Mitochondria and chloroplast have their own Lysosomes

• Mitochondria and chloroplast have their own vesicles

• Mitochondria and chloroplast have their own RNA

• Mitochondria and chloroplast have their own DNA

Mitochondria and Chloroplast are similar to prokaryotic cells like bacteria in what way?

• They have the same lifespan

• They divide the same way

• They are the same color

• They have the same shape

Mitochondria and Chloroplast are similar to prokaryotic cells like bacteria in what way?

• Their DNAs are copies of each other

• Their DNAs both have uracil

• Their DNAs are circular

• Their DNAs both have short lifespans

What is an endosymbiont?

• The process of creating energy inside of a cell

• An organism that lives inside another organism

• An ancient water bacteria that killed a strain of Irish potatoes

• The event in which nutrients are oxidized and turned into CO2

Why do mitochondria and chloroplasts have DNA in them?

• They were once prokaryotic cells.

• They produce their own DNA through photosynthesis.

• They receive the DNA from the nucleus.

• They process the DNA of the cell.

How does the image above best support symbiogenesis?

• Both the bacterium and mitochondrion produce a form of energy

• The mitochondrion has intrinsic DNA

• The bacterium contains a phospholipid bilayer

• The bacterium contains a nucleus
