WebbInterestingly enough, plant and animal cells are also easy to tell apart. Readers will learn the organelles—cell parts—that are particular to animal or plant cells. They will be exposed to the wide variety of plant and animal cells, as well as the characteristics that makes specialized cells so perfectly suited to their functions. WebbAn overview of the differences between these organisms and theories of eukaryogenesis are reviewed. Various methods of investigating the transformation from prokaryotes to …

WebbEukaryote Evolution Protists Slime Molds Fossil records indicate that eukaryotes evolved from prokaryotes somewhere between 1.5 to 2 billion years ago. Two proposed pathways describe the invasion of prokaryote cells by two smaller prokaryote cells. WebbHere, we summarize the history of these endosymbiotic concepts to their modern-day derivative, the “serial endosymbiosis theory”, which collectively expound on the origin of eukaryotic cell organelles (plastids, mitochondria) and subsequent endosymbiotic events. Additionally, we review recent hypotheses about the origin of the nucleus.

WebbIn eukaryotes, histone modifications link gene expression to the physiological state of the cell via carbon-, energy-, and nitrogen-sensing through regulators such as AMPK, GCN2, and TOR. The eukaryotic lineage arose from bacterial and archaeal cells that underwent a symbiotic merger.

WebbThe endosymbiotic theory states that eukaryotes are a product of one prokaryotic cell engulfing another, one living within another, and evolving together over time until the separate cells were no longer recognizable as such.
