Question
Chapter 8, Problem 11TYU
Summary Introduction
To explain:
Whether the DNA sequence of ribosomal RNA gene of chloroplast will be same as the one in the plant nucleus or as that of a photosynthetic bacterium and what does it say about the evolution of photosynthesis.
Concept introduction:
The endosymbiotic theory says that the eukaryotes evolved from prokaryotes. The eukaryotic plant organelle, chloroplast was originally a photosynthetic prokaryote that was engulfed by another organism.

- 1. Why was the great oxygenation event important for mitochondrial development? a) In your own words, define symbiotic. 2. Chloroplasts and mitochondria both contain a circular DNA chromosome, and ribosomes. Why does this evidence support the theory of endosymbiosis as the mechanism for the origin of eukaryotic cells? a) Today, could mitochondria live independently of their eukaryotic cell host? Give two pieces of evidence to support your answer.arrow_forwardThe extra energy required for the evolution of the highly complex eukaryotic cell was possible because: a) mesosomes released enzymes into the nucleus b) two types of prokaryotic bacteria became endo symbiotic invaders of the complex cells c) the DNA of the eukaryote cell functions within the nucleoid area d) chloroplasts were able to use O2 to conduct photosynthesis e) the space between the two layers of the nuclear membrane contained mitochondriaarrow_forward5)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.arrow_forward
- 1a.Discovery of genes controlling Gibberellic Acid (GA) synthesis and perception became very important during the Green Revolution, and remain important today. Why? Select one: a. Mutants with reduced GA levels are dwarfs. Many dwarf plants were important for the Green Revolution because the shorter plants can invest more energy into economically important parts like seeds (instead of stem length). b. Mutants with reduced GA levels are more resistant to herbivore damage (like caterpillars), increasing plant yields. c. Mutants with reduced GA levels allowed farmers to control fruit ripening more accurately. d. Mutants with reduced GA levels have increased photosynthesis 1b. What features are important for overall plant form? Select one: a. Iterative development and capillary action b. Iterative development and apical dominance c. Apical dominance and stomatal conductance d. Phyllotaxis and capillary actionarrow_forwardWhich of the evolutionary sequences below does NOT represent how chloroplasts were derived?
