Exemplars of Phyla of Protozoa

Phylum Sporozoans
Phylum Sporozoans are nonmotile, unicellular protists that host other animals. They are the fifth phylum from the Protist Kingdom. They are parasite that lives on other animals. They invade red blood cells, multiply inside of them, raptures the cells and escape moving on to the next cell. Their apical complexes found in its cellular organization allows it to invade host cells. Symptoms are fever and chills due to the rupture of the red blood cells. One example is Malaria which is one of the most contagious disease in the tropic regions of the world. It is transmitted form the bite of the female Anopheles mosquito. Plasmodium vivax is the best know sporozoan.


Phylum Ciliophora
Phylum Ciliophora have many hairlike cilia that helps propel them through the water.. They have trichoysts structures. They live in marine environments and can also be found in pond water. They consume bacteria. They have two nuclei: micronuclues and macronuclues. One of its characteristics is that it likes to roll its body when moving forward because of the oral groove found on each of its side. The minuscular like structure that they have allow them to move.



Phylum Sarcodina
Phylum Sarcodina is a single celled protist that can take a shape because of its membrane's flexibility. Amoeba is the best know Phylum Sacodina. Amoeba are slow. It stretches out is cytoplasm to function and is considered active.






Phylum Rhizopoda
Phylum Rhizopada are heterotrophic. They feed on bacteria, algae, and other protists. They are a large group of protists that moves with pseudopods. Most Rhizoodians use pseudopods to capture thier prey. Some Rhizopians are important parasites such as Entamoeba Histoltica which causes amoebic dysentary. Entamoeba is a common symbiont in the human mouth. There it feeds on bacteria and human macropahges.

Phylum Zoomastigophora
 They are single-celled, eukarote and heterotrophic. They may form smbolic relationships with other organisms. Phylum Zoomastigophora eat their prey using phagocytosis. Most live alone but some species form colonies of cells. They are named for the flagella that they use to help them move. Some are parasitic. They are found in the gut of termites, and are used to digest the cellulose in wood.

Bacterial Transformation

Bacteral transformation is a process in which bacteria cells invade the naked DNA molecules. If the foregin DNA replication is recognzed by the host cell DNA polymerases then the bacteria will replicate both the foreign DNA and its own DNA. Transformation is when the bacteria abosbed the DNA of the enviroment into it self. Transduction is when a piece of DNA is transported into a cell by a virus. Competent bacteria can uptake certain DNA molecules. They are made with calcium chlordie in the early log phase of growth. This is because the bacteria membrane is non- prermeable to calcium ions but they are permeable to chlordie ions. When chlorie ions enter the cell, water molecules accompay the changed particle. Th ewater intake causes the cells to swell and the uptake of DNA begins. Heat shock genes are genes that helps the bacteria in survivng extreme temperatues.

Time Love and Memory Dicussion

I thought chapter 7 was pretty interesting because in chapter 7, Benzer talks about how he found a new way to look at mutant flies. Lewis recommended a poison called EMS to make the flies sleep so he can look at the traits because traits are similar to everybody. This is how eugenics came into play. The Germans learned about this new study of eugenics and this made the Nazi scientists to try to changed the traits that were more favorable for people. I thought this was very interesting and fascinating as it explained why the NAZI wanted to experimented on people. Even thought its completely ethically wrong, I can see why the Nazis did this because, according to history the Nazis were obsessed with their German race and they believed that the German was superior to everyone else.

Major Plant Division

Gymnosperms
Gymnosperms are seed bearing plants. They were developed in the carboniferous period around 350 millions years ago. Most are extinct but some there have been fossils of them.Their main body is the diploid sporophyte and is differentiated into root, stem, an leaves. Their name means "naked seed". Conifers are the largest gymnosperms. Gymnosperms are non flowering seed plants with seeds that are covered in an ovule.

Angiosperm
 Divison Anthopyta or Angiosperm are vascular with seeds that are similar to gymnosperms but they are flowering plants. The flower are meant to protect the seeds from weather, animals, and humans. The seeds have two layers: inner layer that surrounds the seed and is used for storing food and protecting the seed from danger and a outer layer that protects the seeds from its environment and animals. They also produces seeds and their seeds are enclosed within fruits. Compared to Gymnosperms, Angiosperms have flowers and endosperm within their seeds. Angiosperms have roots, stems, leaves, and flowers. They are classfied into 8 groups: ; amborella, nymphaeales, austrobaileyales, chloranthales, magnoliidae, monocotyledonae, ceratophyllum and eudicotyledonae. Angiosperm have double fertilization.

Bryophytes
Embryophytes or Bryophytes. They are non vascular terrestrial green land plants that lacks the tissue for specialized woody water conducting vessels.Bryophytes are not a natural group as they do not produce flower or seeds.They lack tissue compare to other plants such as ligin or branched sporophytes. Their growth size are limited by their delicate non vascular structure. They first lived 420 million years ago. They make up the Bryophyta group which consists of mosses, liverworts, and hornworts. They can be dioicous or monoicous. Three lineages of Bryophytes are marchantiophyta, bryophyta and anthocerotophyta.

Pteridophytes
Pteridophytes are vascular plants because they possess xylem and phylum. Their xylem lacks companion cells. They are the first vascular land plants. The plant's main body is the sporophyte, which is differentiated into true roots, stems and leaves. The spores born in sporangia reprodcues the sporophytes. Sporangia are usually borne on fertile leaves called sporophylls. Pteridophytes are mostly homosporous, but some are heterosporous with microspores and megaspores. They are also classified as vascular cryptogams. They are separated into two groups: Lycopodiophyta and ferns. They can be dioicous or monoicous.

Thoughts For a Countdown

In this article, Lewis talks about how cellular life on earth is similar. Lewis talks about the Apollo program and how astronauts returning from space would be forced to into isolation and wear surgical masks. It might be implied that the astronaut might have brought a strange virus. Lewis states that our whole society uses biology and science in order for us to understand how things work. Lewis points out that most things on this planet work together in order to succeed.

Societies as Organisms

In this articles, Lewis praises the authors of books on insect behaviors because of how they go in depth to differentiate the uniqueness of insects . In one of the more fascinating comparison in the article, Lewis compares ants to humans and shows how much o an embarrassment that we in so many ways are like ants. Ants farm and they raise livestock, which sounds very familiar to what we do. Ants form armies and fight in battles and uses chemical sprays as a weapon to confuse their enemies which sounds like us humans we form countries and wages war on each but instead of sprays we use guns to kill each other. Lewis also point out a funny but yet sad compassion. Ants capture slaves, something that humans have started since the ancient times and it still has not changed.

Lives of A Cell

In this article, Lewis Thomas argues and compares how the world is similar to a cell. I agree with his compassion. Lewis compares how in this big ball of a world that we live in (earth), things like trees supplies oxygen, bacterias to break things down, and water to generate life in order for earth to "live", all help to make the earth function. Just like a cell, which has many organelles like the smooth and rough ER, the lysosome, and many more important part that works together in order for the cell to function and live. Thomas informs his readers and gives them a tour of the cell using metaphor, analogy, and similes to relate it to the earth so the reader can have something interesting for them to connect with.
