Bio 1011 Chapter 30 Flashcards
Ascocarp
The fruiting body of a sac fungus (ascomycete)
Chitin
a polysaccharide within the cell walls of hyphae that also make up the exoskeleton of insects, crustaceans, and other arthropods
ovary
paired organs that produce mature ovum
Eudicot
flower parts are in fours or fives, have two embryonic seed leaves, or cotyledons
micropyle
The micropyle is the small hole in the seed which shows where the pollen tube went into the ovaries.
Fruit
An organ that develops from the ovary of a flowering plant and contains one or more seeds.
Integument
Layer of sporophyte tissue that contributes to the structure of an ovule of a seed plant.
Spore
An asexual reproductive structure that can develop into an adult found in certain protists (algae), plants, and fungi
Zigomycete
A member of a fungal, characterized by the formation of a sturdy structure called a zygosporangium during sexual reproduction
cross-pollination
a reproductive process in which pollen from one plant is transferred to the stigma of another plant .
seed
sporophyte embryo and its food source packaged in a protective coat
sepals
green, leaflike part of the plower that covers and protects the flower bud before it opens
flower
reproductive organ of angiosperm plants especially one having showy or colorful parts
petals
brightly colored structure just inside the sepals; attracts insects and other pollinators to a flower
stamen
male part of the flower; made up of an anther and a filament
carpel (pistil)
the female reproductive organ of a flower, consisting of the stigma, style, and ovary.
filament
the stalk of a stamen that supports the anther
style
the narrow elongated part of the pistil between the ovary and the stigma
ovary
a structure containing egg cells; the base of a pistil in a flower
anther
pollen producing structure located at the tip of a flower’s stamen
Conifers
Gymnosperms
Naked seeds (no ovary)
Seeds Cones (pollen, seed)
Wind pollinated
haustoria
is specialized hyphae that form symbiosis with host and exchanges (mutualistic) or extracts (parasitic) nutrients
cotyledons
A seed leaf an angiosperm embryo. Some species have one cotyledon, others two
mycorrhiza
special symbiotic relationship between fungus and plant root.
complete flowers
has sepas petals stamens and pistils
sporangium
structure in ferns and some fungi that contains spores
Heterokaryon
A fungal mycelium that contains two or more haploid nuclei per cell.
double fertilization
- one sperm unites with egg to become zygote, which becomes embryo
- one sperm unites with 2 female cells to form the 3n endosperm
- the intugements develop into seed coat
- the ovary develops into the fruit
dormancy
is a condition where seeds will not germinate even when the environmental conditions are permissive for germination
Yeast
Yeast leavened doughs rise and increase in volume due to the action of what?
incomplete flowers
missing one part ( sepals, petals, stamens, or pistils
perfect flower
has stamen and pistil
imperfect flower
has either a stamen or pistil ( not both)
ovule
In seed plants, a structure that contains the female gametophyte and has the potential to develop into a seed.
pollen grains
what microspores develop into; contain the male gametophytes of seed plants; protected by a tough coat can be carried away from their parent plant by the wind or hitchhiking on other moving organisms
monocots
species with one cotyledon; typically have parallel leaf veins; examples include orchids, palms, and grain crops
Zygosporangium
Thick-walled reproductive structure formed from the fusion of the cytoplasm of the mycelia of two neighboring fungi.
Endosperrm
In angiosperm, a nitrient-rich tissue formed by the union of a sperm with two polar nuclei during double fertilization, The endorsperm provides nourishiment yo developing embryo.
Embryo sac
The female gametophyte of angiosperms, formed from the growth and division of the megaspore into a multicellular structure that typically has eight haploid nuclei.
pollination
transfer of pollen from anther to stigma
dicot
leaves have branching veins
roots are tap
flower petals in multiples of 4 or 5
(slides) palisade layer present
stigma
Collects the pollen
