The amoeba proteus is commonly known as the amoeba, the ciliophora are commonly known as ciliates, and the zoomastigina are commonly known as zooflagellates. There are currently more than 200,000 species of protists that have been discovered and documented, and many more have yet to be discovered.
Protists are found pretty much anywhere that water is found. They range from microscopic, single-celled organisms all the way up to large seaweed plants. They are typically seen as the basis of any ecosystem, as they either create energy through photosynthesis which moves up the food chain, or they are eaten themselves and provide energy for many other living creatures. The kingdom Protista poses a problem for scientists because of how vast and diverse it is. The organisms vary greatly in many different categories, and are simply defined as any eukaryote that is not an animal.
Along with their scientific names, many protists also have common names. For example, the name "amoeba" is given to any of the members of the rhyzopoda phylum. While a lot of the names of protists are not commonly known, they may be known for other reasons. For instance, plasmodium is the protist that causes malaria, and giardia lamblia is the protist that causes giardiasis. Many commonly known diseases are a result of ingesting specific protists.Learn More
The organelles that contain digestive enzymes are called lysosomes. These cellular structures primarily function for the breakdown of complex molecular substances, such as carbohydrates, lipids, proteins and nucleic acids.Full Answer >
Nucleotides are the monomer of DNA. They are made of a 5-carbon sugar (deoxyribose), a phosphate group, and a nitrogenous base bound to the sugar. The four different types of nucleotides are adenine (A), thymine (T), guanine (G) and cytosine (C).Full Answer >
Speciation, commonly known as macroevolution, is supported by several lines of evidence, including direct observation, genetic mapping and the fossil record. Several populations have been observed in the act of splitting into new species. Comparison of genomic sequences between species are most easily explained as a result of recent common ancestry and an extensive fossil record has yielded numerous transitional fossils.Full Answer >
Genetic variation is important to evolution because it helps to maintain the health of a population by constituting alleles that may be useful in overcoming stresses such as diseases and pests. Without genetic variation, some of the fundamental mechanisms of evolutionary changes would not operate.Full Answer >
