You need to choose TEN plants from the list given:
1) Green algae
2) Bryophyte (liverwort, moss, or hornwort)
4) Pterophyte (fern, whisk fern, or horsetail)
6) Angiosperm Monocot
7) Angiosperm Dicot
The remaining three can be anything else you find interesting. Have fun with it!
Take photos with your iPad camera (you may need multiple pictures to document the entire plant, leaves (if any), flowers (if any), other interesting structures).
Put together a report (Word or pdf acceptable, but probably easier for all of you if it is a Pages document), on your ten plants. Include for each specimen,
B) Scientific name
C) Where you found it
D) How it is classified
E) Derived features it has (e.g., for the angiosperms, you could say “flower” and “fruit”)
F) Anything else interesting you have learned
G) The source(s) of any information you included that did NOT come from your own brain
P.S. You should be able to find most of these around somewhere (at home, campus, lab. If you have trouble finding one of the list (my guess would be the lycophyte will be the most challenging), it is okay to swap it out with something else you found so you can still have all ten.
Cell Organelles and their Functions
This unit we are learning about cells and the organelles contained within. In this Discussion, we’ll focus on the functions of the various organelles and cell structures:
Cell membrane | Mitochondria | Plant cell wall | Plant chloroplast | Nucleus | Lysosomes | Nuclear envelope | Rough endoplasmic reticulum | Golgi apparatus | Smooth endoplasmic reticulum |Cytoskeleton | Cilia and flagella
- Select four of the organelles or structures above and briefly describe where each is located in the cell, their appearance and the role each carries out.
- Look around your home or place of work and find an item or process that is analogous to each of the four organelles you described. Be sure to explain how that item or process is analogous to the cell structure or organelle; be specific. Here is an example of an analogy:
A record player is like the rough endoplasmic reticulum in that it takes information encoded in the grooves of the record and translates them into a song from start to finish. The grooves in the record are like xxxxx and the song produced is like xxxxxx.
You will need to justify your analogy and provide the information indicated by xxxxxx. You may not use this example and do not use a tape recorder or CD either.
In the Module 4 Case assignment you will have the opportunity to explore the new era of personalized medicine that uses genetic mapping to determine medical treatment. Watch the NOVA video: Cracking Your Genetic Code to learn more about the genetic technology available to us and what it means for medicine, ethics, and the future of human society.
After watching this video, proceed to the following resource and address the topics below in a 2-3 page paper http://www.nature.com/scitable/topicpage/genetic-mutation-1127
- Explain what a genetic mutation is and the difference between inherited mutations versus point mutations.
- Describe how the technology explained in “Cracking Your Genetic Code” can be used to detect mutations and predict your health.
- Form an opinion on whether or not you support utilizing genetic mapping to develop personalized medical treatment. Find evidence to support your opinion and cite your sources. What dangers do you see dangers in knowing our personal genome?
This paper should be approximately 2-3 pages long and reflect the information contained in the resources provided above. When summarizing the information you read from the Nature website, NOVA video, or any resources you use to support your opinions, be sure to synthesize the information into your own words, and cite the references. Please use complete sentences and write your paper in essay format using subheadings to organize the required topics.

PRINCIPLES OF TAXONOMY
As you have learned in Modules 1 and 2, prokaryotes share many common features that differentiate them from eukaryotes, such as:
Lack of nuclear membrane, unicellularity, division by binary-fission and generally small size.
As introduced on the Home page of Module 3, various species differ and can be classified into taxonomic groups based on several characteristics. One characteristic commonly used to differentiate an organism as belonging to one species or another is the potential for the individuals to reproduce sexually and produce viable offspring. However, this characteristic cannot be applied to prokaryotes, and so their identification and classification is often determined based on:
- Phylogeny: All bacteria stem from a common ancestor and diversified since, consequently possess different levels of evolutionary relatedness
- Metabolism: Different bacteria may have different metabolic abilities
- Environment: Different bacteria thrive in different environments, such as high/low temperature and salt
- Morphology: There are many structural differences between bacteria, such as cell shape, Gram stain (number of lipid bilayers) or bilayer composition
- Pathogenicity: Some bacteria are pathogenic to plants or animals
All microbial metabolisms can be arranged according to three principles:
1. How the organism obtains carbon for synthesizing cell mass:
- autotrophic – carbon is obtained from carbon dioxide (CO2)
- heterotrophic – carbon is obtained from organic compounds
- mixotrophic – carbon is obtained from both organic compounds and by fixing carbon dioxide
2. How the organism obtains reducing equivalents used either in energy conservation or in biosynthetic reactions:
- lithotrophic– reducing equivalents are obtained from inorganic compounds
- organotrophic – reducing equivalents are obtained from organic compounds
3. How the organism obtains energy for living and growing:
- chemotrophic – energy is obtained from external chemical compounds
- phototrophic – energy is obtained from light
In practice, these terms are almost freely combined. Typical examples are as follows:
- chemolithoautotrophs obtain energy from the oxidation of inorganic compounds and carbon from the fixation of carbon dioxide. ie: Nitrifying bacteria
- photolithoautotrophs obtain energy from light and carbon from the fixation of carbon dioxide, using reducing equivalents from inorganic compounds.
For example: Cyanobacteria are photosynthetic autotrophs. Cyanobacteria split water, H2O, molecules and use the electrons to reduce carbon in photosynthesis. Water is the electron donor. However, Chlorobiaceae and Chromatiaceae are also photosynthetic autotrophs, but they use hydrogen sulfide H2S as the electron donor, or reducing equivalent donor.
- chemolithoheterotrophs obtain energy from the oxidation of inorganic compounds, but cannot fix carbon dioxide (CO2).
- chemoorganoheterotrophs obtain energy, carbon, and reducing equivalents for biosynthetic reactions by breaking apart organic compounds (made by photoautotrophs). Examples: most bacteria, e. g.Escherichia coli, Bacillus spp., Actinobacteria
- photoorganoheterotrophs obtain energy from light, carbon and reducing equivalents for biosynthetic reactions from organic compounds. Some species are strictly heterotrophic, many others can also fix carbon dioxide and are mixotrophic. Examples: Rhodobacter, Rhodopseudomonas,Rhodospirillum, Rhodomicrobium, Rhodocyclus, Heliobacterium, Chloroflexus(alternatively to photolithoautotrophy with hydrogen)
For this SLP assignment, you will continue to analyze the paper by Urakawa et al. (2012) by considering the characteristics that allow us to classify the prokaryotic organisms in this study as belonging to different Domains. You will use the website:http://www.ucmp.berkeley.edu/exhibit/phylogeny.html
UC Berkeley’s virtual exhibit hall and resource on taxonomy and phylogeny, to complete this assignment.
Review your definitions of Archaea and ammonia-oxidizing bacteria from Module 1. Begin athttp://www.ucmp.berkeley.edu/exhibit/phylogeny.html, webpage titled “Welcome to the Phylogeny Wing. Select the link “Phylogeny of Life” within the first of the “four ways to get started.” You will an overview of the relationship between DNA and the Three Domains of Life. Use this page to begin the research necessary to address these topics in a 3-4 page paper:
- What general characteristics determine whether a prokaryote belongs to the Archaea or Bacteria domain?
- Define DNA and RNA. What role do DNA and RNA play in this determination?
- What role does the metabolism play in classifying Nitrosococcus oceani and Nitrosopumilus maritimusas Archaea or Bacteria?
- Do either of these organisms normally thrive in an environment where crude oil is abundant? What other microbes live in this type of environment?
SLP Assignment Expectations
The Session Long Project consists of an integrative project emphasizing the personalized application of each module’s concepts. For Modules 1–5, students are required to engage in an original integrative project reflecting their comprehensive knowledge of and ability to apply the course materials. Each component of the SLP will be graded on a modular basis.
Your essay is considered a scholarly work. You will be provided with many scholarly references to begin each assignment. For any additional research you are required to do to complete your assignment, please use scholarly references such as a peer reviewed journal article or a government sponsored or university sponsored website. As you read through your sources, take notes from your sources and then write your paper in your own words, describing what you have learned from your research. Direct quotes should be limited and must be designated by quotation marks. Paraphrased ideas must give credit to the original author, for example (Murray, 2014). Direct copying from “homework help” websites will not receive credit.
When you write your essay, please organize your paper to include an introduction (overview of the assignment), body with subtitles (reflecting the requirements of the assignment), and a summary (develop connections between the required topics).
