WebEukaryotic cells, made possible by endosymbiosis, were powerful and efficient. That power and efficiency gave them the potential to evolve new characteristics: multicellularity, cell specialization, and large size. They were the key to the spectacular diversity of animals, plants, and fungi that populate our world today. WebThis process of converting a free-living organism into an organelle is called endosymbiosis (endo- meaning inner) and is also the way eukaryotes evolved mitochondria. All plants, such as the water fern you are looking at, descended from this primary endosymbiosis event that led to the first chloroplasts. Figure 3.7. 1: Primary endosymbiosis. show divorce cast

Explanation of endosymbiosis

WebEndosymbiosis is symbiosis in which one of the symbiotic organisms lives inside the other. Hence the use of the prefix "endo". Does that help? WebThe host cell profited from the chemical energy the mitochondrion produced, and the mitochondrion benefited from the protected, nutrient-rich environment surrounding it. This kind of “internal” symbiosis — one organism taking up permanent residence inside another and eventually evolving into a single lineage — is called endosymbiosis.
