Flagellum

Painted around the year 1470, by an Alsatian artist, this image is unlike no others. Coming from the Northern Renaissance era, the image brings together an idea that has never before been portrayed, which is that of the pre and post crucifixion Christ. The pre crucifixion Christ or also known as the Pensive Christ, seeks to depict the moments of grief, sorrow, desertion, and betray in reference to humankind, whereas the depiction of a post crucifixion Christ reflects on the idea of Christ as…

Movement of cells are important since some cells depends on movement to carry out its major function. For example, sperm cells need to move from one place to another place to carry out reproduction. Movement of cells are supported by cytoskeleton system of the cells. The cyctoskeleton system are composed of microtubules, microfilaments and intermediate filaments. However, for unicellular organisms such as Paramecium, the movement of cells are regulated through cilia or flagella. Cilia can be…

non-mammalian, plants, and humans. P. aeruginosa belongs to the bacterial family Pseudomonadaceae, and is a gram-negative rod that approximately measures 0.5 to 0.8 µm by 1.5 to 3.0 µm. It can normally be found in water and soil. Its single polar flagellum makes it motile, and it is known to be one of the fastest swimming bacteria found in hay infusion and pond water (Crittenden, Trussell, Hand, and Howe 2012). Due the extensive size of the genome, 6.3 million base pairs, P. aeruginosa is…

mitotic spindles that protrude away from the centrisome of cells and are primarily tasked with the creation of microtubules. The microtubules give way to mitotic spindles, which play a vital role in both mitosis and cytokinesis as they give cilia and flagellum the ability to generate motion and they ensure both newly formed cells contain paired centrioles during the later stages of cell division. Kinetochores are protein structures that produce chromosomal movement through the attachment of…

Aedes aegypti is holometabolous, this type of development stages includes the egg, lava, pupa, and the adult stage. The distinct traits to key out this mosquito are, small palps with white scales. The female mosquito can lay as many as a hundred eggs at one batch, after the eggs are laid down, the eggs develop within two days, and once wet the larvae emerge from the egg shortly after (Christopher, 1960). The larvae then mature over the course of the week or longer, depending on temperature,…

The function of Eukaryotic and Prokaryotic cell components by FATIMA MOHIDIN Eukaryotic Cell Eukaryotic cells are cells that contain a nucleus and have membrane bound organelles they are multicellular cells and undertake reproduction by the process cell division known as meiosis and mitosis. There are 2 types of eukaryotic cell: plant and animal cells. They contain organelles such ribosomes, smooth and rough endoplasmic reticulum, mitochondria, nucleolus, centrioles, cell membrane,…

Attila the Hun was a fierce warrior and tough emperor. Although many people know him from shouting, ”Punala!” while trying to have his army rip Ben Stiller in four, he is better known for the beginning the downfall of The Western Roman Empire. Many also never knew that he started his rule working jointly with his brother. When I first started learning about Attila I had three questions: How did Attila come to power? What did Attila do to gain full power? And How did Attila cause the beginning of…

Erwin Schrödinger was a physicist pioneer who gave a series of lectures in 1944. They were published under the title What is Life? (Harold, 2001). Though philosophical in nature, many have wondered if life can be reduced to biology or even further down to chemistry. This sent many scientists looking for the answer and spawned the guiding question, could human life be artificially created at the cellular level? This would consist of arranging the correct amounts of various elements into the…

five parts of the mouse trap away it is then no longer a mouse trap. After showing the example of the mouse trap Behe showed another example, one that was biological and shows that it itself is a design or a creation. This example was the bacterial flagellum or cilium. He went on to show that cilia are not only hair-like parts of a cell used to move fluids in cellular structures but that cilia itself is made up of multiple parts and if you were to take any of those parts away the cilia would not…

a larger size, their digestive systems have evolved with it to become more complex and fit the needs of the organism’s enlarging bodies. A well formed canal system is present in their body, in which a water current is produced by the organism’s flagellum, a thread-like structure that is present in Poriferans. This water current bears food particles to be passed into their bodies through numerous small openings known as Ostia. The food materials are taken from the water current by collar cells,…
