Question
Answer
Order of evolution of 3 main domains   Bacteria, archaea, eukarya  
🗑
Bacteria   -lack a nucleus -circular DNA genome -Include cyanobacteria w/ chlorophyll & can photosynthesize  
🗑
Archaea   Live in harsh environments (called extremophiles for this reason) -extreme halophiles: extreme salty environment -extreme thermophiles: live in extreme heat -methanogens: anaerobes that release methane  
🗑
Protists (Eukarya) 7 main   amoebas, sporozoans, ciliates, slime molds, euglena, diatoms, brown algae  
🗑
amoebas   -unicellular -move using pseudopodia -found in soil, freshwater, and marine environments  
🗑
sporozoans   -animal parasities -life cycles w/ sexual and asexual parts  
🗑
ciliates   -move w/ cilia -EX: paramecium  
🗑
slime molds   -many nuclei -overgrown amoeba  
🗑
euglena   -unicellular algae -move w/ flagellum  
🗑
diatoms   -live in freshwater and marines (producers)  
🗑
brown algae   -multicellular, large seaweeds living in marines  
🗑
Kingdom Plantae sub-categories   -Nonvascular plants -ferns (vascular seedless) -conifers (vascular seed nonflowering) -angiosperms (vascular seed flowering)  
🗑
nonvascular plants   -live in damp areas EX: moss, liverworts, hornworts  
🗑
ferns (vascular seedless)   -have spores instead of seeds (can be scattered)  
🗑
conifers (vascular seed nonflowering)   -gymnosperms -no flower production  
🗑
flowering plants (angiosperms)   -MONOCOTS: single seed leaves, 3 part flower, parallel veins in leaves -DICOTS: 2 seed leaves, 4 or 5 part flower  
🗑
Kingdom Fungi   -eukaryotic heterotrophs -multicellular -cell wall w/ chitin -lack chloroplasts -heterotrphs  
🗑
Divisions of fungi   Zygomycota and Basidiomycota  
🗑
Zygomycota   -sexual reproduction -includes mycorrhizae: mutualistic associations between plant roots and fungi  
🗑
Basidiomycota (CLUB FUNGI)   25,000 organisms -mushrooms, shelf fungi, puffballs  
🗑
8 phylums in kingdom animalia   sponges, coelenterates, flatworms, mollusks, segmented worms, arthropods, echinoderms, chordata  
🗑
Sponges   -sessile: nonmoving -traps water -marina environment  
🗑
coelenterates   -central, sac like digestive system -radial symmetry  
🗑
flatworms   -bilateral symmetry -can be parasitic or nonparasitic  
🗑
mollusks   -soft body. hard shell -have a foot, organ space (visceral mass), mantle (w/ shell)  
🗑
segmented worms   -closed circulation -excretes waste through metanephridia  
🗑
arthropods   -eliminate waste through malpighian tubules -largest and most diverse EX: crustaceans, insects, spiders  
🗑
echinoderms   -radial symmetry -exoskeletons -vascular system (water) EX: sea stars, sea urchins, and sand dollars  
🗑
chordata   fish, amphibians, reptiles, birds, mammals (FARBM)  
🗑
fish   -cartilage, sometimes bone, structures -breathe through gills  
🗑
amphibians   -land and water -metamorphosis -breathe through lungs or skin  
🗑
reptiles   -thick, scaly skin -shells to resist dehydration -cold blooded  
🗑
birds   -tetrapods w/ wings -lay shelled eggs  
🗑
mammals   endothermic -have hair -breathe through lungs  
🗑


   

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
 
To hide a column, click on the column name.
 
To hide the entire table, click on the "Hide All" button.
 
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
 
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
