plant phylums
What are the two phylum's of green algae and which did modern land plants come from?
charophytes and chlorophytes
modern plants came from charophytes
What phylum of fungi are parasitic?
chitridiomycota
What phylum do sponges fall under?
porifera
What three classes fall under mollusks?
bivalvia- clams
gastropoda- snails/slugs
cephalopods- squids
What two classes fall under phylum annelida?
polychaetae and clitellata
What phylum includes plants with sori on the back of leaves for spore production?
pterophyte
What phylum do bread molds fall under and explain their life cycle?
zygomycota
sexual and asexual reproduction, pos and neg haploid hyphae come together to form dikaryotic zygosporangium which undergoes diploid meiosis and a dormancy period which germinates to make spores
What phylum do jellyfish fall under and what are the two body forms?
Cnidaria
medusa and polyps
What two phylums have radial symmetry?
cnidarians and ctenophorans
What classes fall under subphylum chelicerata?
merostomata and arachnida
What phylum does moss fall under and what makes their life cycle unique compared to other plants?
bryophyte, the gametophyte stage is dominant to the sporophyte
What phylum do mushrooms fall under and what is their life cycle like?
Basidiomycota
sexual repro only, diploid zygote fuses to undergo haploid meiosis and produce spores, dikaryon mycelium forms from mating strains to eventually become the mushroom
What phylum is an acoelomate?
platyhelminthes
What phylums are classified as ecdysozoans?
nematodes, tardigrades, and arthropods
What classes fall under subphylum mandibulata?
malacostraca and hexapoda
What phylum do vascular plants fall under and what three subphylums fall under it?
tracheophyte
1. lycophyte- club mosses
2. pterophyte- ferns
3. spermatophytes- angio/gymnosperms
What phylum do yeast and truffles fall under, and what is the life cycle life?
ascomycota
haploid hyphae come together to fertilize and make the body during a dikaryon phase, then diploid meosis occurs and then haploid mitosis occurs to form 8 spores per diploid cell
What two phylums are pseudocoelomates?
nematodes and rotifers
What subphylums fall under arthropods?
chelicerata, mandibulata, and myriapoda
What classes fall under subphylum myriapoda?
chilopoda and diplopoda
What subphylum do flowering/fruiting plants fall under?
angiosperms
What is mycorrhizae and what two types exist?
mutualistic relationships between fungi and plants
arbuscular- penetrates roots
ectomycorrhizae- surrounds roots
What three phylums are coelomates?
annelids, mollusks, arthropods
What two phylums fall under deuterostomes?
echinoderms and chordates
What class do starfish fall under?
asteroidea
