The Eukaryotic Organism Of Protista

4. Modern taxonomists (scientists who classify organisms) no longer use the classification of the kingdom of Protists. List the three other kingdoms of Eukarya.

Eukaryotes include all living animal organisms other than the eubacteria and archaea. The eukaryote has a nucleus membrane that surrounds the nucleus in which the way they defined the

In this lab, we examined protist survival in different communities. An biological community is a community where two or more species coexist in

Since they do not contain a nucleus they would be in the prokaryotic domain. They would need to be from the kingdoms Bacteria Specifically Eubacteria. They use photosynthesis to produce their own food. This animal is most likely Prochlorococcus. This is the most abundant photosynthetic cell in the ocean. Another one is cyanobacteria or blue green algae, but they are prokaryotic unlike algae. They could be grouped by their shapes like cyanobacteria are spherical, rod, and spiral. They can also be grouped as photosynthetic since they have

Prokaryotic cells do not have a nucleus. The chromosomes which are found in prokaryotes are usually spread in the cytoplasm. In eukaryotic cells the chromosomes remain together inside the nucleus and there is a clear nuclear membrane that is surrounding the nucleus.

Bacteria are prokaryotic, and if you were to observe the two cells under a light microscope, you could distinguish their differences. The biggest distinguishment you can make while carefully observing the two cells, is the lack of a nucleus in a prokaryotic cell as compared to a eukaryotic. Prokaryotes also lack any membrane-bound organelles.

A separate group classified Unknown A as an animal cell, as well as, described it as oval shaped, clear, and had more than one round structure, which they claim was a nucleus. I disagree with this observation. Animal cell come in different shapes and sizes and are not necessarily clear. Another claim is that Unknown A was an ameba cell because of its abnormal shape and its organelles. Although, my group concluded that Unknown A was a protest, the claim that it is an ameba is likely too. The reason being is because protist cells and ameba cells are very similar

They are known as a diverse group of unicellular eukaryotic organisms. They are also defined as a single celled organism with animal like behaviour. Protozoa are microscopic cells that range from a size from 10 to 52 micrometers. Some protozoa are larger than most. For example the xenophyophores are around 20 centimetres in diameter. Free living forms are restricted to moist environments, such as soil, mosses and aquatic habitats. Many protozoa are symbionts.

Bacteria and Archaea are prokaryotic, which are mostly single-celled incomplex microorganisms. Both Bacteria and Archaea have a variety of prokaryotes classified in multiple kingdoms (Reece, et al., Campbell Biology, 2014). There are a number of scientists who believe that Archaea cells may be the precursor to Eukaryotic cells and that they have more in common with Eukaryotes than Prokaryotes (Madigan, Martinko, & Dunlap, 2009).

2. Kingdom Protists- these organisms solely do not depend on themselves to create food but on other living things.

The trophozoite of N fowleri consists of an amoeba surrounded by a two-layer membrane. The cytoplasm contains free and bound ribosomes, as well as membrane-bound organelles. A smooth endoplasmic reticulum, a Golgi-like structure, mitochondria, vacuoles, and nucleus-containing nuclear envelope are present. Microfilaments create a supportive cytoskeleton. The N fowleri flagellate is pear-shaped. The cytoplasm has fewer vacuoles, and the components of a flagellar apparatus (flagellum, basal body, rootlet) are present. The spherical cyst is enclosed in a mucous-sealed porous cell wall. The cytoplasm contains enlarged mitochondria and the nucleolus is less pronounced.

The Domain Eukarya is one of the three domains recognized in Linnaean taxonomy. Within the Domain Eukarya is the Kingdom Protista. This Kingdom is extensive but can be subdivided into three general categories: slime molds, protozoa, and algae. Each of these subdivisions has unique characteristics that distinguish them from one another. Prime examples of these different characteristics can be found in Physarum, Giardia, and Spirogyra.

The observed protist had long, unbranched filaments with cells connecting to each other from end to end. This alga seemed to contain a central constriction in between each cell. The protist had a considerable length and appeared to bear a slight bend in its structure. The alga seemed to be around other protists of the same species in large

Prokaryotic Cells All living things are made of cells, and cells are the smallest units that can be alive. Life on Earth is classified into five kingdoms, and they each have their own characteristic kind of cell. However the biggest division is between the cells of the prokaryote kingdom (monera, the bacteria) and those of the other four kingdoms (animals, plants, fungi and protoctista), which are all eukaryotic cells. Prokaryotic cells are smaller and simpler than eukaryotic cells, and do not have a nucleus. Prokaryotic means 'pre-nucleus' and eukaryotic means 'true nucleus'.

Eukaryotes come in two grades of organization: single-celled (protists) and multicellular (plants, animals, and fungi). The world today is full of complex multicellular plants and animals: how, why, and when did they evolve from protists?
