Advanced Biology III Exam Review Biodiversity

Phylogeny

Is the evolutionary history of a species or groupings of related species using fossil, molecular, and genetic DNA

Taxonomy

Is the ordered division and naming of organisms

Linnaeus

Published a system of taxonomy based on resemblances and increasing broad categories

Binomial Nomenclature

The two part scientific name of a species

Genus

First part of name of a species two part scientific name. A taxonomic category above the species level

Species

Second part of name of a species two part scientific name

Domain, kingdom, phylum, class, order, family, genus, and species

Taxonomic species from broad to narrow

Taxon or taxa

A taxonomic unit at any level of hierarchy

Bacteria, archaea, and eukarya

Three domain system

Peptidoglycan

Bacterial cell wall that is a network of sugar polymers cross linked by polypeptides

Taxis

The ability to move toward or away from certain stimuli

Binary Fission

Prokaryotes reproduce this way, quickly by dividing every 1-3 hours. Cell division. A method of asexual reproduction. Does not involve mitosis in prokaryotes but in eukaryotes mitosis happens

Protists

Are eukaryotes and have organelles and are more complex than prokaryotes

Photoautotrophs

Which contain chloroplasts

Heterotrophs

Which absorb organic molecules or ingest larger food particles

Mixotrophs

Which combine photosynthesis and heterotrophic nutrition

Endosymbiosis

Taking in the another cell as an organelle. A process in which a unicellular organism, the host, engulfs another cell, which lives inside the host cell and ultimately becomes and organelle

Symbionts

Benefiting from their hosts. The smaller participant In a symbiotic relationship living in or on the host

Producers

An organism that produces organic compounds from CO2 by harnessing light energy or oxidizing inorganic chemicals

Euglenids

Have one or two flagella that emerge from a pocket at one end of the cell, can be both autotrophic and heterotrophic

Dinoflagellate

Are a diverse group of aquatic Mixotrophs and heterotrophs with two flagella

Diatoms

Are unicellular with a unique two part, glass like wall of hydrated silia

Golden Algae

Are named for their color, which results from their yellow and brown carotenoids

Brown Algae

Are the largest and most complex algaw, most are marine called seaweeds

Red algae

Are reddish in color due to an accessory pigment called phyrsoeythrim, which masks the green of chlorophyll, are usually multicellular and large

Green algae

Are named for their grass green chloroplasts

Ciliates

A large varied group, are named for their use of cilia (tiny hairs) to move and feed

Plasmodium

Is the Protist parasite that causes malaria

Amoebas

Move and feed by pseudopodia and characterized a protist

Pseudopodia

False feet

Slime molds

Are brightly pigmented and usually are yellow or orange, once thought to be fungi, also known as mycetozoans

Heterotrophs

Absorb nutrients outside of the body

Yeasts

Single cell fungi common body structure

Mycelia

With networks of branched hyphae adapted for absorption

Hyphae

One of many connected filaments that collectively make up the mycelium of a fungus

Chitin

Most fungi have cell walls made out of this

Mycorrhizae

Are mutually beneficial relationships between fungi and plant roots

Spores

How fungi reproduces as either sexual or asexual. A haploid cell that produces a mycelium after germination

Bud cells

Asexual reproduction in which outgrowths from the parent form and pinch off to live independently or else remain attached to eventually form extensive colonies

Zygomycetes

(Phylum zygomycota) include fast growing molds, parasites, and commensal symbionts

Ascomycetes

(Phylum ascomycota) live in marine, fresh water, and terrestrial habitats

Asci

A saclike spore capsule located at the tip of a dikaryotic hypha of a sac fungus

Ascocarps

The fruiting body of a sac fungus

Sac fungi

Common name for ascocarps

Basidomycetes

(Phylum basidiomycota) include mushrooms, puffballs, and shelf fungi, mutualists, and plant parasites

Basidium

Club like structure

Club fungi

Another name for basidomycetes

Lichen

Is a symbiotic association between a photosynthetic microorganism and a fungus in which millions of photosynthetic cells are held in a mass of fungal hyphae

Mycosis

General term for a fungal infection in animals
