Chapter 25, Problem 10TYK
According to the endosymbiont theory,
- a. the first primitive cells may have originated when a lipid bilayer spontaneously formed around abiotically produced
polymers. - b. plants were able to colonize land with
fungi as symbionts within their roots. - c. the mitochondria and plastids of eukaryotic cells were originally prokaryotic endosymbi-onts that became permanent parts of the host cell.
- d. the infoldings and specializations of the plasma membrane led to the evolution of the endomembrane system.

A group of environmentalists is studying the effects of recent commercial zoning to wildlife acreage on the biodiversity of a rural county. The group noted a steady decline in the population of animals, while bacteria and other protists remained constant. Which statement best discusses the reasons for the steady decline of animals as opposed to the protists?
A. Bacterial growth is usually not affected by environmental changes because of asexual reproduction.
B. The animals could not adapt to the new environment.
C. Bacteria lived in areas that were not affected by the zoning
D. The animals became susceptible to human and environmental harm.
According to the endosymbiotic theory, why was it adaptive for the larger (host) cell to keep the engulfed cell alive, rather than digesting it as food?
A.
The host cell would have been poisoned if it had digested the engulfed cell.
B.
The host cell was able to survive anaerobic conditions with the engulfed cell alive.
C.
The engulfed cell provided the host cell with CO2
D.
The engulfed cell provided the host cell with ATP.
E.
The engulfed cell allowed the host cell to metabolize glucose.
Which of the following statements is the MOST compelling argument that fungi are more closely related to animals than plants?
A.
Plants have chloroplasts whereas fungi and animals cells do not.
B.
Plants fix carbon dioxide from the air; fungi and animals use pre-existing organic molecules.
C.
The DNA sequences of ribosomal RNA of fungi share more homology with ribosomal RNA from animals than plants.
D.
Both animal and fungal cells are eukaryotic.
