Paramecium

There were five cells observed while conducting the experiment. The five cells consisted of cardiac muscle, elodea (a plant), paramecium (a protist), rhizopus stolonifer (bread mold, a fungus), and Bacterial cells (bacilli). Each cell was observed under high power lens (except for rhizopus stolonifer) with a total magnification of 400μm and a dFOV of 400μm. The estimated object size, scale bar, and drawing magnification of each cell was found except for cardiac muscle. Each cell appeared much…

system. Starting with monera, we can distinguish monerans as organisms without set internal features, as they are prokaryotic cells (no membrane bound organelles). In my analysis, I deemed Paramecium as a moneran, however, it was later proved that Protococcus was the solo moneran out of the group. Rather, Paramecium was a protist, along with Spirogyra. Protists are single celled, and can display both animal and plant-like characteristics. Fungi are also plant-like, but they are multicellular and…

Emma Potochny Sam Pappas 1. Background Information This should include background on the scientific question you wish to address, why it is important, information on the study species, and why it was chosen to answer this question. This information should lead the reader to the logical basis of your hypothesis. Animal models are still commonly used in product testing, especially for bath products. These substances are usually injected into or rubbed on the laboratory animals in eye or skin…

present, the Euglena is able to produce carbohydrates from carbon dioxide in water and absorb nutrients through this process, a relatively simple digestive process compared to more advanced organisms. In addition Euglena, Paramecium is also a Protozoan. Digestion of a Paramecium begins when food enters its open mouth from an oral groove, and soon after, the gullet,…

An osmotic problem Paramecium faces is that excess water enters the cell because it is hypotonic to its environment. As a result, they need to use contractile vacuoles to get rid of excess water in the cell, enabling it to osmoregulate. Compare the ideal osmotic environment…

Characteristics can classify organisms into 5 key groups called the 5 kingdoms: - Protoctista: These are mainly unicellular organisms that also have a nucleus. Some examples of protoctista are paramecium, amoeba and unicellular algae. -Prokaryotes: These are also unicellular organisms like protoctista but unlike them, they do not have a nucleus. An example of a Prokaryote is bacteria. Some prokaryotes are able to make their own food which makes them more self-sufficient. These types of…

it turgid, which allows the plant to stay upright. This is because it has a cell wall, which prevents it from lysing. A cell without a cell membrane must instead find adaptations to this, especially when submerged in a hypotonic environment. The Paramecium has a contractile vacuole which takes in the water as it enters the cell. When the vacuole becomes full, it expels the water out of the cell, which regulates the amount of water inside the cell.…

Under 100x magnification – a view of purple rod shaped bacteria/bacilli; some appear as either single rods or paired rods (diplobacillus). Yoghurt prepared – under 40x magnification Yoghurt prepared – under 100x magnification * Fresh yoghurt. Under 40x magnification – a view of loads of bacteria moving about with undefined shapes. Under 100x magnification – an indistinct view of loads of varied bacteria moving about, such as diplococci, streptococci, staphylococci,…

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 found in a large quantity on the plasma membrane of the organisms. They move around by paddling back and forth like a boat. They surrounded the plasma membrane…

Biology is the study of living or deceased organisms (Biology Department, 2015). There are two overarching classes to these organisms: prokaryotes and eukaryotes (Reece et al., 2014). Prokaryotes (meaning before nucleus) are put in two domains: Bacteria and Archea (Biology Department, 2015). Eukaryotes on the other hand, (which have nuclei), are in the Eukarya domain and encompass all other organisms such as plants, animals, fungi and protists (Biology Department, 2015). The most effective way…
