Insects undergo what?Complete and incomplete metamorphasis
How do you define a true bug?Triangle on back
Arachnids include what 4 things?Spiders, scorpions, ticks, and mites
Millipedes have what compared to centipedes?2 sets of legs per segment instead of 1
Eating difference between millipedes and centipedes?Milli's are plant eaters and centipedes are carnivores
The phylum annelids include?Earthworms, leeches, polychaetes; segmented worms
Common features of Phylum Mollusca?Shell, Mantle, Radula, found on water and in land

2 characteristics of CnidariaCarnivores and radial
What is Coral bleaching?When coral eats algae that is too hot because of rising temperatures. The algae gives it color so the algae turns white, eventually dies

Question Answer
Characteristics of plantsMulticellular, Eukaryotic, photosynthesizers, autotrophs, producers, cellulose in cell walls, sessile
What does Sessile mean?Bend toward sun, adaptations for spreading seed, resistance to predation
What are some plant adaptations?Related to protists, specialized structures for support, gravity, and desiccation
4 classification of plantsNon-vascular, vascular seedless plants, gymnosperms, angiosperms
Characteristics of mosses, liverworts, hornwortsBryophytes, non-vascular, small, lack true leaves and roots, live in very moist areas, rely on diffusion
What is the moss lifestyleSperm swim from male to female during rainstorm, diploid embryo forms and develops, diploid develops a capsule which bursts and releases haploid spores, spore lands on oist soil and grows
Economic value of mossUsed in gardening, hold soil crust together, smoky flavor of scotch
Evolution of vascular tissueTubes allow for transport of water and nutrients, root development through water and support
Characteristics of ferns and horsetailsVascular and seedless, mostly tropical, reproduce using spores, lack nutrients, DNA RNA proteins
Who are the primary species of coal forests?Ferns and horsetails
Characteristics of gymnospermsConifers, cycads, ginkgos, gnetophytes, naked seed, needless, vascular
What's the tallest tree?Coast Redwood (380 ft)
What's the oldest tree?Methuselah (4,800)
Flowering plants, majority of earth, grasses, vascular, covered seedAngiosperms
AntherProduces pollen
FilamentSupporting Stalk
StamenMale reproduction
CarpelFemale reproduction
StigmaSticky tip
StyleElongated stalk
OvaryContains ovules
Sexual reproductive structureFlower (angiosperm)
Advantages of angiosperm seedsDormancy, nourishment, germination
Dormancy definitionRemain inactive until good conditions
Angiosperm seed dispersal techniquesHitching a ride, flying and floating, providing a food source
Plant defensesAnatomical structures, sticky traps, chemical compounds
Closely related to animals, eukaryotic, lack chlorophylls, chitin, herterotrophic, multi and unicellularFungi
Feed by absorption, secrete enzymes, we see small portionfungi
importance of fungiDecomposers, commercial uses, fungi parasites
