Hey Mrs. Anderson! I have a question, where did Eukaryotic Cells come from
That's a great quetsion!
The Endosymbiotic theory is a scientific theory that explains how a large host evolved into Eukaryotic cells.
This theory says that billions of years ago, there were prokaryotes.Much like there are today.They had been around for a long time. some of these large prokaryote cells engulfed some of these small bacteria, but instead of those small bacteria getting digested, some of them remained intact within the large prokaryote and actually began to live in symbiosis.
The two cells became dependent on one another for survival. Over millions of years of evolution, the smaller injested bacterial cells developed into specialized organelles like mitochondria and chloroplasts that adds to a more complex type of cell, a eukaryotic cell.
The 2 cells being dependent on another and developing here.
Wow thank you for explaining!
Remember that this is still happening today! And since this is a scientific theory this isn't just some guess, it has been backed up with facts.
