Protist

others do not. There are currently two classification systems of organisms, into 5 kingdoms or 3 domains, both are distinguished by specific characteristics. Kingdom Monera have no well defined internals as they lack membrane to bound organelles, and Protists are single celled organisms that may be plant or animal-like. Fungi are multicellular and plant-like, but are not green, while Plants are multicellular and usually green. Animals are multicellular and without plant-like characteristics. The…

Those of first three kingdoms contain multi-celled organisms, animals, plants and fungi. Otherwise, two other kingdoms, bacteria and protists are categorised mostly as single-celled organism (but some are multi-celled species). Recently, there is a new tree family revealed by recent research and made up two main divisions that are the Prokaryotae and the Eukaryotae (Woese et al 1990;…

be considered commensalism. Now, Protists are unicellular organisms from the kingdom Protista. An example of a parasitic protist would be Plasmodium which causes Malaria. The prostist enters the blood stream, clogging capillaries and blood vessels, while destroying blood, which leads to death if untreated. Protists can do good as well. The protist Zooxanthellae , has a symbiotic relationship with coral reefs. Because Zooxanthellae is a photosynthetic protist, it acts as a food source to for…

Microorganisms can be classified as fungi, bacteria, protists, prions, archaea, and viruses. They are claimed as non-living. Microorganisms are known to be single-cellular, or unicellular. Unicellular protists are sometimes seen by the human eye, whereas multicellular protists are sometimes microscopic. They live in several places on earth such as inside rocks within theearth's crust, human skin, a cow’s stomach…

Organisms: Eukarya Terms: (u CARE ee uh) contains complex organisms (the eukaryotes) that have cells with nuclei. Eukarya, organisms include protists, plants, animals and fungi Eukaryotic cells are larger and more complex than prokaryotic cells. In addition to a nucleus, they contain many other internal structures (organelles), including mitochondria and chloroplasts. Importance to Evolution: Eukarya are important to evolution these cells are considered a milestone in the…

for billions of years however, 1.6bya during the Proterozoic era, we suddenly find the emergence of complex eukaryotic cells. All eukaryote cells share one common ancestor which emerged just once in 4 billion years of life on earth and all plants, protists, algae, animals and fungi are constituted by these cells. The cellular structure of bacteria and eukaryotes are so different there is no evidence to support the ‘directional’ evolution of eukaryotes from bacteria.. Biologists can’t explain…

Forensic science, known as forensics, is the application of science to law by analyzing DNA for legal evidence. DNA profiling is the predominant application and forensic science, DNA profiling allows us to take more than one sample of an unknown DNA specimen and determine if it has the same genetic match. Moreover, DNA profiling is to help determine and solve crime scenes such as murders, assaults, and rapes. The technique used for analyzing DNA is restriction fragment length polymorphism…

The purpose of this lab was to study a local lake using it as an example of an lentic community. A lentic community is an aquatic community that is comprised of standing water, lake or pond, as opposed to flowing water, river. Samples of both biotic and abiotic factors at the field site were taken. The biotic factors are the living organisms while the abiotic factors are the physical and chemical samples. A plethora of photosynthetic autotrophs and heterotrophs constructed the population of an…

On the outside of the Paramecium you can find the radiatin canal and a contractile vacuole. The cytoplasm, food vacuoles, the macronucleus, and the micronucleus are located inside. Another characteristic of them is that they move faster than other protists. They live in aquatic environments, but most usual in warm water. Paramecium uses the process phagocytosis to capture their prey. It likes to eat bacteria, dead plant, algae and animal matter. They are able to do sexual and asexual…

though the prokaryotes seem to be very different from the eukaryotes. For example, humans look very different from the bacteria, but they still do share some characteristics. No matter at which cell you are looking at: bacteria’s`, plants`, animals`, protists`, etc., they all will be bounded by a plasma membrane (Biology Department,2015), and contain a nucleic acid: such as DNA, RNA, cytoplasm, and ribosomes. The things that prokaryotes will not have are organelles. Organelles can be known as…
