Question
Chapter 4, Problem 3S
Summary Introduction
To determine:
Whether the flagella are an example of a homologous or analogous trait considering the structure and function of the flagella found on eukaryotic and prokaryotic cells.
Introduction:
In terms of evolution, the homologous traits are derived traits are similar in structure as they are evolved from and the analogous traits are similar in function. Analogous trait is an example of the convergent evolution and homologous traits are inherited from the common ancestor.

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.
The endosymbiotic theory pertains to which organelle within eukaryotes because of
the presence of 70S ribosomes, circular DNA, and the replication of this organelle
independent from mitosis?
O 1) nucleus
O 2) lysosomes.
O 3) golgi
4) endoplasmic reticulum
5:
O 5) mitochondria
Genetically speaking, prokaryotes are different from eukaryotes because:
a. prokaryotes usually have one main circular chromosome, whereas eukaryotes have multiple linear chromosomes
prokaryotes do not usually have histone proteins to package their DNA
prokaryotes do not have a nucleus to house their DNA as eukaryotes do
prokaryotes have less total DNA than do eukaryotes
All of the above

- Evolutionary microbiologists developed a theory about a common ancestor for all eukaryotic cells. Below is a model of the theorized changes during the origin of eukaryotic cells. Prokaryotes are not capable of phagocytosis, or engulfing outside particles by creating a pocket in the cell membrane. Which of the following changes in early prokaryotes could be predicted to result in the emergence of eukaryotic organisms? A - the development of genetic transfer mechanisms in prokaryotes B - the evolution of predatory or parasitic relationships in prokaryotes C - the emergence of collections of cells functioning together in prokaryotes D = the expansion of internal structures to support larger individual cells in prokaryotesarrow_forwardAccording to the theory of endosymbiosis, organelles, like mitochondria and chloroplasts, were once free-living cells that were absorbed into another cell. The relationship benefited both cells to stay together. What evidence do scientists observe today that supports the theory of endosymbiosis? Select all that apply. a There are ribosomes found inside mitochondria and chloroplasts just like there are inside cells. b Looking inside mitochondria and chloroplasts, one will find that they each contain their own DNA. c Mitochondria and chloroplasts are found inside all cell types. d Mitochondria and chloroplasts each have a membrane around them just like a cell would.arrow_forwardWhat types of biological abilities can be combined to create more capable, more complex cells? How does the presecence of different types of ribosomes inside a eukaryotic cell strengthen the endosymbiotic theory? How does chloroplasts and mitochondria found within a cell have two membranes? How does the emergence of endosymbotic theory change the way humans view microorganisms? Will people be comfortable imaginning that the life functions of pants and animals, including their own, are actually dependent on the coexistence of many different microscopic pieces?arrow_forward

- Make a T-chart using the following paragraph: All living organisms will fit into two different categories; prokaryotes and eukaryotes. Eukaryotes, the more complex cells, are made up of one or many cells. These eukaryotic cells have a nucleus and membrane-bound organelles. Prokaryotes, the simpler cells, do not have a nucleus or membrane-bound organelles. Almost all the prokaryote organisms are single-celled. It is important to know that the only way we can see these organisms is by using a microscope.arrow_forwardBased on the presence of mitochondria and chloroplast within eukaryotic cells, what organelle do you think originated within eukaryotic cells first: mitochondria or chloroplast? Why?arrow_forwardA scientist has discovered a new species and is tasked with identifying which of the kingdoms of life the organism might fit. Multicellular with nuclei Presence of a cell wall containing chitin Heterotrophic Non-motile Question options: Fungi Protista Plantae Animalia Protists are a group of organisms that are eukaryotic. However, they are a diverse group, with some of the members of the group having a more recent common ancestor with plants while others have a more recent common ancestor with animals. Algae are protists that are more closely related to plants than any other group. Which characteristics would algae share with plants but NOT with animals?
