which tissues are unique to animals? nervous and muscle
diploblastic 2 germ layers (ecto and endo)
triploblastic 3 germ layers (ecto, meso, and endo)
acoelomate no body cavity
pseudocoelomate body cavity partially lined with mesoderm
coelomate body cavity completely lined with mesoderm
functions of body cavities acts as circulatory system, provides support, allows space for organs
four characteristics of chordates notochord, dorsal/hollow nerve cord, pharyngeal slits or clefts, and muscular/post-anal support
madreportite found in starfish and allows for entry of water into the water vascular system
non-vascular plants mosses, liverworts, and hornworts
all non-vascular plants are...? bryophytes
vascular plants subtypes seedless and seed
seedless plants club mosses, ferns, horsetails, and whisk ferns
seed plants subtypes gymnosperms and angiosperms
gymnosperms "naked seeds", conifers, pines, cycads, ginkgo, and gnetae
angiosperms "seeds with fruit", "flowering plants"
angiosperms subtypes monocots and dicots
vascular bundles xylem (water and minerals) and phloem (food)
plants (oldest to newest) algae, bryophytes (mosses), ferns (seedless), gymnosperms, and angiosperms

fruit has... an ovary and the fruit protects the seed
double fertilization 3n endosperm - only occurs in angiosperms
3 tissue types in mature plants dermal, ground, vascular
dermal tissue "epidermis", has stoma for gas exchange
ground tissue most of plant body and is the main location for photosynthesis and carb storage
3 types of ground tissue parenchyma (photosynthesis, support, storage of minerals), collenchyma (flexible support), sclerenchyma (strength and support)
types of vascular tissue xylem (water) and phloem (sugar)

simple fruit compounds dry and fleshy
dry fruit subtypes fruits with 1 seed and fruits with 2+ seeds
fruits with 1 seed achene and nut
fruits with 2+ seeds capsule, legume, and follicle
fleshy fruit substypes ovary with 1 seed and ovary with many seeds

ovary with many seeds berry, ponae, apple
compound fruits fruits formed from ovaries of many flowers and several ovaries in one flower, multiple fruit aggregate, pineapple, strawberry, and raspberry
coniferophyta pines and cedars - cones and needle leaves
ginkgophyta maidenhair tree - broad fan shaped leaves with seeds borne singly on stalks
