Unicellular Organelles

Analyze the anatomical structure of ten different organelles in the cell and their respective functions.

You may use the lab manual, pre-lab lectures, and credible internet resources, however you may not use your cell bio lab classmates as a resource. You will most likely see this material again on the Final and I highly encourage you to work individually and seek help from myself or your TA. Plagiarism will result in an automatic zero.

Cilia are tiny hairs, which protect parts of the respiratory tract by capturing particles, which has entered the body by using a sweeping movement to keep the particles such as dust and debris out of the lungs. The cilia are found attached to the apical surface of the cell. For example, dust that has been breathed in through the nose would be captured to stop it going even further. There are roughly 200 to 300 tiny hairs on the cell.

Before you buy cilia and flagella it is important to understand their functions and structures. Both cilia and flagella are whip-like columns of microtubules, covered in a membrane. They serve to move liquids across or over the surface of a cell, and can also be used to transport the cell from point A. To point B. There are 3 different types of flagellum, and 2 different types of cilia.

P1 – Describe the microstructure of a typical animal cell and the functions of the main cell components. A typical animal cell is seen as a tiny, three dimensional sac which is in fact made up of many components, each as important as the other. The microstructure of an animal cell was in fact uncovered mainly through the use of both cell fractionation and electron microscopy. Each main component has its own, individual function which helps a cell to function and maintains the cell membrane. The components that I will be describing include the cell membrane, nucleus, cytoplasm, mitochondria, lysosomes, Golgi bodies, centrioles, endoplasmic reticulum (both smooth and rough) and ribosomes.

If I could develop my own organelle to put inside a eukaryotic animal cell, the organelle would fight cancer. This organelle would be surrounded by lipid bilayer to keep its own strong chemicals inside. The chemicals would kill the cancer, eventually being processed out by the body as

Nucleus: The nucleus is the largest organelle in most cells. It controls eating, movement and the reproduction of the cell. The nucleus holds all the DNA information of the cell. Surrounding the nucleus is a double membrane called the nuclear envelope. The nuclear envelope holds the nucleus together and makes sure it keeps everything inside the nucleus.

There are ways in which unicellular organisms and single living cells are both alike and different. A unicellular organism is a single cell that can function entirely on its own. A single living cell cannot live on its own and must be part of an organism. In this essay, we will be comparing and contrasting unicellular organisms and single living cell.

In order for cells and organisms to “live” they need to perform certain tasks such as produce energy through respiration, send messages, maintenance and reproduction. To enable the cell to do so, it contains within small structures called organelles, each organelle is different and carries out a specific function.

This micrograph demonstrates that these organelles is a Nucleus because by looking at this, I can see the dual membrane structures. I can see that nucleus having a sphere-shaped organelle found in eukaryotic cells. Furthermore, I can see that it contains genetic material where it is darkening. In addition, I am also able to see the endoplasmic reticulum. This overall proves me that it is nucleus.

Animal cells are very complex and organized eukaryotic organisms. Each and every one of their organelles contain a specific form and function. Ever wondered how an animal cell works? Well, there are countless things in this world that functions the same way. For example, a hospital!

The study of motile cilia has been very significant with a range of models and experiments that scientists have conducted specifically for knowledge of the cells ambiguous occupation in the human body. In comparison to the other study’s conducted one stands out most of all. It is the the algae, Chlamydomonas reinhartii, a biflagellate single cell organism whose cilia express a set of proteins that provide a necessary function in the motile human cilia. The main causal difference in types of cilia most likely derived from expression of sensory receptors on the motile cilia to attain material from the environment. “It has been posited that enhanced specialization of cilia lead to the development of complex sensory organs such as the retina” (Biosci

The structure of cilia in an animal cell is that they have hair-like structure which extends outwards from the surface. Cilia’s structures are very important in an animal cells because they develop every day and are important in the cells cycle. They are between 1 to ten micrometres long with less than a micrometre wide. Cilia has 2 different types that can work either together or they work separately; they are called motile which suggest moving and non-motile which suggest antenna that receives sensory information for the

Vertebrate primary cilia are best known for their sensory roles. In the visual system, the

Although both Archaeal and bacterial cells possess flagella for motility, the composition of each organism’s flagellum is very different. In bacterial cell, the flagellum is composed of a basal body, external protein filaments both are joined together by a third component called the hook.(Bacteria Flagella David Gene Morgan , Shahid Khan). In Archaeal, the protein filament is polymerised, glycosylated and very much thinner. The Archaeal flagellum is believed to be similar to the bacteria IV pilus in structure.(www.uniprot.org/keywords/974).
