Concept explainers
Eukaryotic cells consist of several organelles, including Golgi complex, mitochondria, endoplasmic reticulum, flagella and cilia, chloroplast, microfilaments and microtubules, and lysosomes. The key reaction happening in the mitochondrion is

- Describe the Theory of Endosymbiosis. a) Briefly define the Endosymbiotic Theory. 2 pts,b) Explain why the Theory of Endosymbiosis is considered a “theory” and not a “hypothesis.” 3 pts,c) Provide a description of eukaryotic and prokaryotic cells, including at least 4 similarities and 4 structural differences. 4 pts,d) Describe the sequence of events with anaerobic ancestral proto-eukaryotes and aerobic prokaryotes that led to the formation of mitochondria and chloroplasts inside eukaryotic cells. (Be sure to define aerobic and anaerobic respiration.) 6 pts,e) Explain how each, the anaerobic ancestral proto-eukaryotes and aerobic prokaryotes, benefited from the relationship. 4 pts,f) Describe 7 pieces of evidence for this scientific theory. Some of this evidence will consist of a list of similarities between mitochondria characteristics and bacteria characteristics. Along with this list of similarities, explain HOW the characteristics are similar. 10 pts,g) The Endosymbiotic Theory…arrow_forwardWhat is the motive behindGenome Project 10 K?arrow_forwardQ4: What is the antibiotic that is used in this experiment presented in the Antibiotic-Resistant Bacteria Connect Activity? Penicillin Streptomycin E. coli Agar Q11: According to the Connect activity, analogous structures do not offer evidence of evolution. However, the presence of analogous structure in two organisms does actually provide us with information about their ancestory. What is this information? the organisms share a common ancestor prior to the evolution of the structure the organisms share a common ancestor after the evolution of the structure the organisms can share no common ancestor.arrow_forward
- What evidence supports the endosymbiotic theory?arrow_forwardBriefly discuss the following topics, including appropriate examples for each:3.1. Genomic fingerprinting for the phylogenetic analysis of bacteria 3.2. Photosynthetic pigments and environmental habitats of green sulphur bacteria3.3.
