Protists are primarily unicellular organisms that are not plants, fungus or animals, and are classified based on how they obtain their nutrition, and whether or not they are able to move. Animal and fungus-like protists are heterotrophs, which means that they do not make their own food and must obtain it from outside sources. Plant-like protists, such as algae, are autotrophs, which indicates that they produce their own food.Know More
Animal-like protists include protozoans, which are classified according to if they move by flagella, pseudopodia or cilia. An example of a protozoan would be zooflagellates, which use one or two flagella to move. Some types of algae are protists. They are members of the protista family that act like plants, although some algae are true plants. Fungus-like protists include slime mold, and are decomposers that have an external digestion process.
Many protists reproduce asexually using binary fission. Others reproduce sexually in a process called conjugation. Most protists have specialized body parts that allow them to move, eat and digest food, remove excess water and reproduce. Some have a soft, flexible outer membrane while others are rigid and retain their shape.Learn more about Molecular Biology & DNA
A codon is a series of three nucleotides used to specify a specific an amino acid. These nucleotides are labeled with G, C, and A and are found in both RNA and DNA. T-containing codons are found in only DNA, and U-containing codons only in RNA.Full Answer >
Cyanobacteria all live in aquatic environments and use photosynthesis to make their own food. Additionally, all cyanobacteria belong to the larger class of bacteria, which is one of the largest groups of organisms. Most cyanobacteria are unicellular, and they typically live in large colonies.Full Answer >
Characteristics of inbred children include mental and physical abnormalities such as impaired cognition and birth defects, according to a 2014 article in PLOS ONE. Inbreeding increases the frequency with which genetic disorders are expressed, thus causing individuals to exhibit potentially damaging traits.Full Answer >
The characteristics of animal-like protists, or protozoans, include the need to obtain food from their environment since they cannot make it themselves, and an ability to move around in their environment to obtain that food. As protists, they are all single-celled organisms that have nuclei and other membrane-bound organelles.Full Answer >
