How did endosymbiosis change life on earth?

Answer 1

The theory of endosymbiosis speculates that a large prokaryotic cell allowed smaller prokaryotic cells to inhabit inside, creating more efficient eukaryotic cells.

Eukaryotic cells possess membrane bound organelles, some of which are double membrane bound, e.g. mitochondria and plastids. Such organelles also contain prokaryotic type ribosomes and circular DNA.

Endosymbiosis is an attractive theory because it explains how life on earth could have progressed by natural selection.

Endosymbiosis changed life on Earth by leading to the development of eukaryotic cells. This symbiotic relationship between different types of prokaryotic cells, particularly between a host cell and engulfed bacteria, led to the formation of organelles such as mitochondria and chloroplasts. These organelles are essential for processes like respiration and photosynthesis, which significantly contributed to the diversity and complexity of life forms on Earth.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
