Linnaeus's two-word system for naming organisms is called binomial nomenclature.

Taxonomy is the science of naming and classifying organisms

All scientific names must have two Latin words

The basic biological unit in the Linnaean system of calssification is the species

An advantage of our scientific naming system is that biologists can communicate regardless of their native languages

Under the Linnaean system of classification, plants and animasl are sorted into groups based on form and structure

The largest division that a group of organisms can belong to is a domain.

Protista is an example of a kingdom

Similar genera are grouped into an family

A species is a narrowly defined group of organisms

Each level of classification is based on shared characteristics

A biological species is isolated reproductively from other species

A hybrid is produced from interbreeding between closely related species

Dogs and wolves are members of the same family, the same genus, but different species

The biological species concept is difficult to apply to asexually reproducing organisms

Similar features evolved through convergent evolution are called analogous characters

Analogous structures perform the samde function in organisms

A protist may be unicellular and heterotrphic, unicellular and autotrophic, and multicellular and autotrophic

The kingdom Protista includes most of the single-celled eukaryotes, slime and water molds and multicellular seaweed.

Protists are found almost everywhere there is water

Proteists: damp soil or sand as protists: oceans

Eukaryotes that lack the features of animals, plants, or fungi are placed in the kingdom Portista

You have been given an unknown organism to identify. You find that it is unicellular and has a cell wall. Which of the following must it also have? Asexual Reporduction

When Chlamydomonas reproduces asexually, it divides by mitosis, and producing haploid gametes

Zoospores are produced as a result of mitosis

The haplod, gemete-producting phase in the life cycle of some portists is knwon as the gametophyte generation

The marine green alga Ulva reproduceds sexually by alternation of generations

Pseudopodia are used for movement by amoebas

Amoebas capture food by engulfing it

When an individual diatom gets too small because of repeated division, it slips out of its shell, grows to full size, and regenerates a new shell.

Algae are found in both fresh water and salt water.

Kinetoplastids reproduce sexually and asexually, are unicellular, cand cause diseases in humans.

Euglena is an example of a protist that is both autotrophic and heterotrophic

Dino flagellates: flagella as ::amoebas : pseudopodia

The process in which two Paramecia coame together after meiosis to exchange parts of their genetic material is called conjugation

RTTIA. Exvess water in the body of the Paramecium is forced back out by the structure labeled E

RTTIA. The stucture that contains the cell's chromosomes is labeled B

RTTIA. Structure E is the contractile vacuole

RTTIA. The sturcture that contains fragmented chromosmes used in routine cellulat functions is labeled A

Pseudopodia and cilia : locomatoin structures as ::food and contractile: : vacuoles in Paramecia

In addition to causing diseased, protists also affect humans through their role in the nitrogen cycle, the diseases they transmit to plants, and the diseases they cause in livestock

Giardiasis is a diease that is spread through contaminated food and water

African sleeping sickness is spread by tsetse flies

Which of the following are human diseases caused by protists? amebic dysentery, toxoplasmosids, malaria

giardiasis: contaminated water :: malaria : mosquito

The protozoan that causes malaria reproduces in the red blood cells of a human

Malaria is caused by several species of Plasmodium

The stage in the life cycle of Plasmodium in which it lives in mosquitos and is injected into humans is called the sporozoite, and follow a cycle.

The symptomas of malaria include delirium, sweating and, include severe chills and fever

Quinine can be used to relieve the sympotoms of malaria

Chitin is found in fungi and in the outer shells of insects

The individual filaments that make up the body of a fungus ae called hyphae

Reproductive structures in which spores from are known as sporangia

Mycorrhizae aid in the transfer of minerals from the soil to a plant

A lichen consists of a fungus and an alga in a symbiotic relationship.
