is a complex red algal cell-wall poly-saccharide that has numerous applications in the food industry
obtained from red algae to seperate DNA molecules by gel electrophoresis
Rhodophyta (red algae), Chlorophyta (green algae), Plantae (land plants), Glaucophyta(blue-green plastids)
4 protist phylums
seeds produce only one cotyledon (part that nourishes embryo); examples: lilies, daffodils, tulips, palms, corn, grasses
gas; causes certain fruits to ripen; recognized as plant "stress hormone"
Spores form in a club-like structure. Short lived reproductive structures called fruiting bodies, bears spores called basidia. smuts and rust cause serious damage to corn wheat...
e.g. mushrooms, bracket fungi on tree and puffballs.
Vascular plants
contain xylem and phloem for transporting materials. 2 types of spore producing and seed producing.
eg. for spore: club mosses, horsetail, ferns
eg. for seed: Gymnosperm (cones) and angiosperm ( flowers)
fungi imperfecti
do not have sexual reproduction stage
what cycles are plants part of
oxygen/carbon dioxide
flowers, fruits, and endosperm
Angiosperms are distinguished from gymnosperms by the presence of
three introns
liverworts lack what that is generally present in mitochondrial genes of other plants
mitosis; zygote
Plant embryos develop by repeated ____ from a single-celled ________ resulting from fertilization.
fungal sexual reproduction
generates new allele combinations that may allow fungi to colonize different types of habitats
multicellular red algae used as a wrap for sushi
moist habitats and microscopic in size
protists common characteristics
fungal mycelia that have the shape of roots; transport water to other parts of the same mycelium
fossil foraminiferan shells
extensively used to infer past climatic conditions
The fusion of the nuclei of mated gametes is a process most accurately defined as
trimerophytes and psilophytes
several early plant lineages once exsisted but became extinct. including:
modern and fossil seed plants are also formally known as what?
plant plasma membrane
ingrowths vastly increase the surface area, which means things can move in and out of the cell quicker
slimy mucilages
cell coverings or cell walls that provide protection from attack by herbivores or pathogens
Strong, found in the cell wall of fungi.
seed dispersal
wind, water animal fur, eaten by animals and then excreted.
ciliophora avoidence behavior
move away from unpleasant enviorments can sense toxins
extensively branched veins
leaves of other vascular plant phyla have
megaphylls "large leaves"
more competent when it comes to photosynthesis
Parasitic Protists
notable for often using more than one host organism
cytoplasmic streaming and osmosis
are important cellular processes in hyphal growth
K/T event
marks the end of the Cretaceous period and begining of the Teritiary period
Plant Structure
their role is to support and collect nutrients in the soil and from air avoiding dessication
non vascular plants
have neither true vascular tissue nor true roots, stems, or leaves
carbon dioxide, water, and minerals
fungal partner provides to the photosynthetic partner
phagotrophs, osmotrophs, autotrophs, and mixotrophs
protist nutrition occurs in four basic types:
evolved several times
leaves and seeds have evolved how many times?
(1) ascomycete hyphae have simple pores in their septa and lack clamp connections, whereas basidiomycete hyphae display complex septal pores and clamp connections (2) ascomycetes produce sexual spores in sacs, while basidiomycetes produce sexual spores on
how can ascomycetes be distinguished from basidiomycetes?
flagellar motion is not powerful enough to keep larger bodies from sinking
flagellates are typically composed of one or only a few cells are small
to increase genetic variability and regenerate maximum size

they are more effective for dispersial
remains of ancient plants
much of todays coal is a result of what?
accessory pigments are able to absorb underwater lught and transfer the energy to chlorophyll a for use in photosynthesis
How do autotrophic protists use accessory pigments?
mitotic cell divisions of parent to progeny
all protists are able to reproduce themselves by asexual means that involve what?
the sporophyte generation is the larger, more complex, and longer-lived generation
what happens in all land plants except bryophytes ?
the development of first substantial soils, the evolution of modern plants, and the ability of animals to colonize land
