- The concept of endosymbiosis as applied to chloroplast and mitochondria found in eukaryotes: a) is based on evidence that Chloroplasts and Mitochondria were originally prokaryotes, b) changes present day animals into plants, c) explains how chemical evolution caused the appearance of life, d) allowed chloroplasts to carry out aerobic metabolism, e) all are true.Serial endosymbiosis is the most supported theory on how the first eukaryotic cells evolved from prokaryotic cells. The figure depicts the evolution of eukaryotic cells which include links to prokaryotic cells from early in the history of life. Identify the cellular structures involved in the connection of eukaryotic and prokaryotic cells. Describe the characteristics of the cellular structures that supports the evolutionary connection. State a claim on how eukaryotic cells evolved. Using evolutionary evidence justify your claim. The cells modeled above are a result are descendants of an original cell.According to the hypothesis of serial endosymbiosis, (a) life originated from nonliving matter (b) the pace of evolution quickened at the start of the Cambrian period (c) chloroplasts, mitochondria, and possibly other organelles originated from intimate relationships among prokaryotic cells (d) banded iron formations reflect the buildup of sufficient oxygen in the atmosphere to oxidize iron at Earths surface (e) the first photosynthetic organisms appeared 3.1 bya to 3.5 bya
- 1) Evolution describes the change of the genetic makeup of __________ A)a population. B)an individual. C)a species. D)a cell 2) Which of the following would not be classified as a eukaryote? A)bacteria B)protista C)animals D) fungi E)plants 3) Which of the following is not a domain of life? A)Animalia B)Bacteria C)Archaea D)Eukarya5)Which of the following observations constitutes evidence that mitochondria evolved before chloroplasts? Mitochondria are aerobic. Chloroplasts are photosynthetic. Aerobic bacteria evolved before photosynthetic bacteria (cyanobacteria). Some protists have separately evolved their own plastids (chloroplast-like structures) through endosymbiosis of cyanobacteria, or even through endosymbiosis of photosynthetic protists. All Eukaryotes have mitochondria; only a subset of Eukaryotes have chloroplasts.One piece of supporting evidence for the endosymbiotic theory for the origin of eukaryotic cells is thata. eukaryotic cells have internal membranes.b. mitochondria and chloroplasts have their own DNA.c. Golgi bodies and endoplasmic reticulum were present in ancestral cells.d. the nuclear membrane could only have come from another cell.
