Asterids

Chytridiomycota

a phylum of fungi that's primarily aquatic with flagellated zoospores; responsible for recent declines in amphibian species

Zygomycota

a phylum of fungi exemplified by bread mold

Ascomycota

a phylum of fungi that includes truffles, morels, and chestnut blight

Basidiomycota

a phylum of fungi that includes mushrooms, rusts, smuts, and puffballs

crustose lichen

a lichen that appears as flat, two dimensional coloring on the substrate it's growing upon

foliose lichen

a lichen that appears leafy, closely appressed to the substrate it's growing upon

fruiticose lichen

a lichen species that appears as a "bushy" clearly three dimensional entity such as reindeer moss or old man's beard

zygotic meiosis

a life cycle in which the organism is largely haploid wherein the zygote undergoes meiosis to restore the haploid state

meiotic gametogenesis

a life cycle in which the organism is largely diploid with specialized structures that produce haploid gametes by meiosis

sporic meiosis

a life cycle in which a diploid phase produces spores by meiosis and a haploid phase produces haploid gametes by mitosis

phycobiont

the algal partner in a lichen

mycobiont

the fungal partner in a lichen

mycorrhiza

a symbiotic relationship between fungi and the roots of plants

lichen

a symbiotic relationship between fungi and algae

Thigmotropism

tropism caused by either the hormone auxin promoting cell elongation or by diffusion and osmosis

(T or F) Tropisms that result from the movement of ions followed by osmosis are reversible as opposed to those that result from differential cell elongation which are non-reversible

true

(T or F) Phototropism involves auxin stimulating cell elongation on the lighted side of a plant resulting in growth of the stem toward the light.

false

(T or F) Phototropism involves auxin stimulating cell elongation on the shady side of a plant resulting in growth of the stem toward the light

true

(T or F) Gravitropism occurs in response to the action of auxin promoting cell elongation.

false

Plant Structure Labeling

axillary bud, petiole, blade, internode, root system, terminal bud, shoot system, node, phytomer

(T or F) Gravitropism occurs in response to the action of auxin inhibiting cell elongation

True

(T or F) When guard cells swell with the influx of water stomata are opened, and the loss of water from guard cells causes stomata to close

True

Tropisms that result from the movement of ions followed by osmosis are non-reversible as opposed to those that result from differential cell elongation which are reversible

False

This tropism is caused by the hormone auxin inhibiting cell elongation

gravitropism
