gravitropism
movement in response to touch
thigmotropism
pattern of growth and development is influenced by environment

all of the above
have a single flagellum on cells with a flagellum
in fungi, hyphae are thick filaments that are resistant to drying out
true or false
false, thin and vaulernable to drying out
in fungi, the feeding structures are typically above ground and the reproductive structures are typically below ground
true or false
false
which of the following is true about ectomycorrhizal fungi
the hyphae penetrate the cell walls of the plant roots
the plant receives sugars from the fungus
the fungus receives N and P from the plant
they are common in temperate fores
they are common in temperate forests
true or false
endophytes are fungi that live in the above ground parts of plants (leaves and stems)
true
hyphae have two distinct types of haploid nuclei
heterokaryote
joining of hyphae to form heterokaryote
plasmogamy
joining of haploid nuclei within heterokaryote to form zygote
karyogamy
true or false
in fungi, a zygote undergoes meiosis to produce haploid spores
true
true or false
molds reproduce asexually by producing spores via mitosis
true
Form arbuscular mycorrhizal associations with plant roots.
glomeromycota
Includes cup fungi; bakers and brewers yeast; some form lichens.
ascomycota
Live in aquatic environments; some have sperm, eggs, and spores with flagella; some are parasites in amphibians.
alternation of generations
chytrids
During sexual reproduction, form ball-like structures that withstand harsh conditions.
zygomycota
Includes most ectomycorrhizal fungi; some digest wood; some are bioluminescent; includes mushrooms and puff balls.
basidiomycota
some animals
are autotrophic
have cell wells
are unicellular
none of the above
none of the above
what embryonic tissue is present in triple lasts but not diploblasts
mesoderm
true or false
In protostomes, the first opening that forms during gastrulation becomes the mouth, and in deuterostomes the first opening becomes the anus.
true
A coelom is a space in the body of animals that contains fluid and does not open to the external environment.
true
A true coelom is surrounded by tissue that is derived from mesoderm.
false
elongated body with distinct head and tail regions and a central nervous system
bilateral symmetry
round body with multiple planes of symmetry
radical symmetry
filters food particles from the water
suspension feeder
feeds on food particles on or in the ground
deposit feeder
eggs develop within mothers body live birth of young
ovoviviparous
young develop within mothers body and are nourished by mother, live birth of young
viviparos
external fertilization occurs in many aquatic animals
true or false
true
In animals with indirect development, the larvae typically live in the same place and eat the same foods that the adults do.
true or false
