Was the mitochondrion or chloroplast first? - cell biology
Nov 11, 2014 · Mitochondria evolved before chloroplasts. We know this because Mitochondria form a monophyletic group: e.g. all life with mitochondria traces back to a single common ancestor ( source ).
What came first mitochondria or chloroplasts? – Sage-Advices
Dec 10, 2020 · Mitochondria, often referred to as the “powerhouses of the cell”, were first discovered in 1857 by physiologist Albert von Kolliker, and later coined “bioblasts” (life germs) by Richard Altman in 1886.
Cell theory | Definition, History, Importance, Scientists, First ...
Dec 7, 2024 · organelles of eukaryotic cells Eukaryotic cells contain membrane-bound organelles, including a clearly defined nucleus, mitochondria, chloroplasts (unique to plant cells), a Golgi apparatus, an endoplasmic reticulum, lysosomes, and peroxisomes. (more)
Ch 25 learning curve and homework assignment Flashcards
- Both mitochondria and chloroplasts evolved simultaneously and resulted in different descendant evolutionary lineages. - Chloroplasts evolved first because there was little to no oxygen available in Earth's early atmosphere for mitochondria to use as a final electron acceptor.
The Origin and Diversification of Mitochondria - ScienceDirect
Nov 6, 2017 · Mitochondria evolved from an endosymbiotic alphaproteobacterium (purple) within an archaeal-derived host cell that was most closely related to Asgard archaea (green). The earliest ancestor of mitochondria (that is not also an ancestor of an extant alphaproteobacterium) is the pre-mitochondrial alphaproteobacterium.
Endosymbiosis: AP® Biology Crash Course | Albert.io
Mar 1, 2022 · Endosymbiosis is an evolutionary theory which posits that eukaryotic cells arose from prokaryotic cells. The theory further articulates that the mitochondria found in today’s eukaryotes evolved from aerobic bacteria and that the chloroplasts found in today’s plant cells arose from cyanobacteria.

The Genomes of Mitochondria and Chloroplasts Are Diverse; Mitochondria and Chloroplasts Probably Both Evolved from Endosymbiotic Bacteria; Mitochondrial Genomes Have Several Surprising Features; Animal Mitochondria Contain the Simplest Genetic Systems Known; Some Organelle Genes Contain Introns
The origin of mitochondria and chloroplasts - Nature
Mitochondria and chloroplasts likely evolved from engulfed prokaryotes that once lived as independent organisms. At some point, a eukaryotic cell engulfed an aerobic prokaryote, which then...
Mitochondria and Chloroplasts – Fundamentals of Cell Biology
Explain the evidence for the endosymbiont theory, which states that mitochondria and chloroplasts were once free-living bacteria. Compare and contrast the genomes of mitochondria and chloroplasts. Explain how proteins that are encoded by the nuclear DNA enter the mitochondria or chloroplasts.
Energy Conversion: Mitochondria and Chloroplasts
The common evolutionary origin of the energy-converting machinery in mitochondria, chloroplasts, and prokaryotes is reflected in the fundamental mechanism that they share for harnessing energy.
