Biology Test Notes from study guide

Goodluck

Define things

• Prokaryote: a unicellular organism with no nucleus and cell organelles

• Eukaryote: an organism that has a nucleus cells and cell organelles

• Autotroph: Produces Its own food

• Heterotroph finds its own food

• Aerobic: requires oxygen to survive and produce energy

• anaerobic: does not need oxygen to survive

Antibiotic resistance is when a strain of bacteria becomes immune to an antibiotic

Antibiotic kills the bacteria however they do not kill the virus

Euglena possess mixotrophy as its unique ability

A red tide is when alge multiplies rapidly and the cause of red tides are Dinoflagellates

Traits always come first

Classification order goes Domain Kingdom Phylum Class Order Family Genus Species and the phrase to remember is Definitely keep ponds clean or frogs get sick

Carl Linnaeus devised a hierarchical system of classification

two name system is called binomial nomenclature

the most specific taxon is the species

3 domains exist currently

Bacteria is unicellular with no nucleus has a cell wall and some are harmful and some are useful

Archeria unicellular with no nucleus or membrane bound organelles some lives in extreme conditions

Eukarya a mix of unicellular and multicellular organisms

Animalia multicellular heterotroph NO CELL WALL

Plantae multicellular autotroph cell wall made of cellulose

Fungi multicellular heterotroph cell wall made of chitin

Protista most are unicellular heterotrophic or autotrophic some have a cell wall and some don’t

they all have a nucleus.

Gram positive will stain purple gram negative will stain pink

Protozoa animal like protists heterotrophs classified based on how they move

Algae Plant like protists autotrophs classified based on if they are unicellular or multi cellular

Molds fungus like protist heterotrophs (decomposers)
