What is Endosymbiotic Theory ? How does it explain Eukaryotic Cells?
What evidence do scientists have to support this theory ?
Based on the video of the amoeba sisters.

1.States that organelles such as chloroplasts and mitochondria were once free-living prokaryotes which eventually lived symbiotically within larger cells, forming modern day eukaryotes.

2.Eukaryote, any cell or organism that possesses a clearly defined nucleus. The eukaryotic cell has a nuclear membrane that surrounds the nucleus, in which the well-defined chromosomes (bodies containing the hereditary material) are located.

A) Carbon dioxide



The main purpose of cellular respiration is to produce ATP. However, one of the byproducts is carbon dioxide. We use the process of cellular respiration when we take in oxygen (so oxygen isn't the answer) and breathe out CO2. Cellular respiration takes place in the mitochondria, but that's not what's released.
