A protist is an organism in the Kingdom Protista. Protists belong to a very large, diverse group of organisms that are all eukaryotic, and most are unicellular. Examples of protists include red algae, amoeba and slime molds.
Protists vary in their movement, and they are separated in locomotion categories of cilia (hair-like projections), flagella (thread-like, whip appendages) and pseudopodia (temporary projections). They also vary in the way they gain energy, as often a single method of acquiring energy is specific to a single protist. The four groups of protist energy are: photosynthetic autotroph, chemosynthetic autotroph, heterotroph by ingestion and heterotroph by absorption.Learn More
DNA sequencing is used to identify individual genes within the DNA of any organism. This information can be used to identify variants and mutations that cause diseases and disorders.Full Answer >
Heredity factors influence what an organism develops into because of genetic influences, whereas the environment plays a role in determining what the organism becomes. One example of this is height, which is partially determined by the person's genes, but is also determined by dietary differences.Full Answer >
According to the Merriam-Webster Dictionary, "non-pathogenic" means that an organism does not cause disease, so non-pathogenic bacteria do not cause illness. Some bacteria are helpful within their environments.Full Answer >
An organism's genotype is the entire set of genes that it carries in its genome, and its phenotype is the observable effect of those genes on the body and behavior of the organism. Biologists draw a distinction between genotypes and phenotypes to clarify the difference between an organism's genetic heritage and the effects that its combination of genes has.Full Answer >
