Essentially, it theorizes that complex cells evolved from simpler cells through symbiosis with other simple organisms. Supposedly structures like mitochondria were originally separate organisms that developed symbiotic relationships with simple protobacteria and eventually evolved into organelles.

EzraThe theory of endosymbiosis helps explain the origin of eukaryotic cells from prokaryotic cells. It suggests that mitochondria and chloroplasts within eukaryotic cells were once free-living prokaryotes that were engulfed by a host cell and formed a symbiotic relationship. This theory is widely accepted as the explanation for the presence of these organelles in eukaryotic cells.

What are the three parts of attribution theory?
The three parts of attribution theory are locus of control (internal or external), stability (stable or unstable), and controllability (controllable or uncontrollable). These factors help explain how individuals interpret and explain the causes of their own behavior and the behavior of others.
How does the meaning of the root words endo- and -symbiosis help you understand the meaning of endosymbiosis?
The root "endo-" means within or inside, while "symbiosis" refers to a relationship between two different organisms. Endosymbiosis specifically describes a symbiotic relationship in which one organism lives inside the other. In the context of endosymbiosis theory, it explains how certain organelles like mitochondria and chloroplasts originated from engulfed prokaryotic cells living symbiotically within a host cell.
How does the theory of evolution help to explain the similarities in all life forms?
The theory of evolution explains the similarities in all life forms by proposing that all living organisms share a common ancestry. Through the process of natural selection, organisms that share beneficial traits are more likely to survive and reproduce, leading to the preservation of these traits in future generations. Over time, this gradual accumulation of genetic changes results in the diversity of life seen today.
What are the key concepts and principles of biology that are essential for understanding the natural world?
Key concepts and principles of biology essential for understanding the natural world include evolution, cell theory, genetics, ecology, and the structure and function of living organisms. These concepts help explain how living things interact with their environment, adapt to changes, and maintain balance in ecosystems.
What are the unifying themes in biology?
cell theory molecular basis of inheritance relationship between structure and function diversity of life arises by evolutionary change evolutionary conservation cells are information processing systems living systems exist in a non-equilibrium state
