a.

Summary Introduction

To determine: The bacterial group from which a chloroplast is likely to evolve.

Introduction: The two basic types of cells are eukaryotic and prokaryotic cells. Bacteria and archaea are considered as prokaryotes in terms of lacking membrane-bound organelles, internal membranous structures, and the cytoskeleton.

b.

Summary Introduction

To define: The term “metagenomics”.

Introduction: Prokaryotes have evolved approximately 3.5 billion years ago and extensively adapted to various structural and metabolic adaptations. Phylogeny is a diagrammatic hypothesis about the history of evolutionary relationship in a group of organisms.

Summary Introduction

To determine: The way by which metagenomics contributes to the prokaryotic phylogeny.

Introduction: The study of genetic materials recovered directly from the environmental samples is called metagenomics.

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…
Please, help: Question: Evolution of Prokaryote into the Eukaryote cell type. A. What are the significant the significant changes that are represented in the evolution of the prokaryote cell type into the eukaryote cell. B. Why are these changes (major differences) important in the process of evolution of more complex organisms?
