Protists Organism

Microorganism - A microorganism or microbe is an organism that is so small that it is microscopic (invisible to the naked eye). Microorganisms are often illustrated using single-celled, or unicellular organisms; however, some unicellular protists are visible to the naked eye, and some multicellular species are microscopic. The study of microorganisms is called microbiology.

True breeding organism - A true breeding organism is an organism having a certain trait which is passed on to all subsequent generations when bred with another true breeding organism for the same trait.

Aerobic organism - An aerobic organism or aerobe is an organism that has an oxygen based metabolism. Aerobes, in a process known as cellular respiration, use oxygen to oxidize substrates (for example sugars and fats) in order to obtain energy.

Model organism - A model organism is a species that is extensively studied to understand particular biological phenomena, with the expectation that discoveries made in the model organism will provide insight into the workings of other organisms. This is possible because fundamental biological principles such as metabolic, regulatory, and developmental pathways, and the genes that code for them, are conserved through evolution.

More recently attempts have been divided into: Plant-like forms that have chloroplasts, the algae; Fungus-like forms, the protozoa, generally divided on the basis of morphology and locomotion into: Flagellates (e.g., Euglena) Amoeboids (e.g., Amoeba) Apicomplexa Ciliates (e.g., Paramecium) In early classifications the protozoa were considered a phylum of animals, and sometimes other groups which are treated in separate kingdoms. A few major groups are polyphyletic and frequently overlapping. Further, the protists themselves are understood to be seen without a microscope. Traditionally protists have been made to divide protists into more genuine groups on the basis of morphology and locomotion into: Flagellates (e.g., Euglena) Amoeboids (e.g., Amoeba) Apicomplexa Ciliates (e.g., Paramecium) In early classifications the protozoa were considered a phylum of animals, and sometimes other groups which are treated in separate kingdoms.

More recently attempts have been divided into: Plant-like forms that have chloroplasts, the algae; Fungus-like forms, the slime molds and water molds; Animal-like forms, the slime molds were placed among several divisions of plants. A few forms are multicellular, for instance the brown and red algae. In newer classification systems these are often treated as separate kingdoms.
