what is the size of algae?
range in size from tiny microscopic life to giant ocean kelps over 30m long
where do algae live?
in the driest deserts, the coldest tundras, and all types of waters (extremophiles)
phykos
"alga"
phycology
study of algae
phycologist
someone who studies algae
how are algae culturally important?
harvested in Ireland during potato famine, tied to folklore and myths
how are algae commercially important?
red algae polysaccharides: agar and carrageenan; brown algal polysaccharides:
alginate
how much oxygen does algae produce?
70% of the oxygen in the atmosphere; produce approximately 330 billion tons of oxygen
annually
algae
photosynthetic, oxygen-producing aquatic bacteria or protists
Great Oxygenation Event (GOE)
2.4 billion years ago; sudden proliferation of cyanobacteria that produced so much
oxygen that their abundance converted Earth's atmosphere from oxygen deplete to
oxygen rich (paved the way for complex life to evolve 500by later!)
how many species of algae are there?
50,589 living species; ~14,000 are diatom species (Dr. Michael Guiry - algaebase)
plants vs macroalgae traits
no vascular material like xylem and phloem, no flowers, seeds, pollinators, no high level
of specialized organ differentation
,ocean pollinators & algae
isopods transport spermatia from red alga, Gracilaria gracilis
which alga can produce lignin?
Calliarthron cheliosporioides (red alga); thought to have independently evolved
what specialized structures have algae developed for living in seawater?
holdfast for anchorage, stipe to support blades, blades to maximize surface
area, pneumatocysts (air bladders) to provide buoyancy and keep algae upright
microscopic symbiotic algae examples
algae living within freshwater coelenterate Hydra and green algal-fungal symbiosis with
lichen, Nephroma
how are macroalgal groups differentiated?
pigments (not always colors you see), cell wall components (what it's made of),
chloroplast structure, storage products, presence or absence of flagella, and
uninucleate or multinucleate cells
coccoid
algal body type (solitary, unicell); small, round ball shape (MOST COMMON)
colony of coccoid
algal body type (solitary, unicell); several cells arranged loosely or in highly organized
ways
coenobial colony
algal body type (solitary, unicell); colonies with a genetically defined number and pattern
of cells
flagellate colony
algal body type (solitary, unicell); unicellular and colonial algae propelled by flagella
uniseriate, unbranced filament
algal body type; composed of a single row of cells, unbranched
multiseriate filament, branched filament
algal body type; composed of cells arranged in more than one row, dividing in a
direction perpendicular to main filament axis
coenocytic
algal body type (macroalgae); siphonous bodies, composed of one very large
multinucleate cell
a type of protist body that is multinucleate and without transverse walls except in some
cases during reproductive development
parenchymatous
algal body type (macroalgae); defined cells composed of tissues (i.e. blades, kelp)
pseudoparenchymatous
algal body type (macroalgae); may appear to be composed of tissues (true
parenchyma), but are filamentous in construction (actually composed of closely-
interwoven filaments
phaeophyceae
brown algae
rhodophyta
red algae
chlorophyta
, green algae
red algae pigments
chlorophyll a, phycobilins, a and B-carotene, xanthophylls
green algae pigments
chlorophylls a and b, B-carotene, lutein, other carotenes, xanthophylls
green algae storage products
plant-like starch
green algae cell covering
wall of cellulose/other polymers, organic scales on some, some naked, some calcified
pigments in algae
allow algae to absorb many wavelengths of light for photosynthesis
watermelon snow
algae that live in high-irradiance environments like on a snowy mountain; red-colored
areas are patches of algae that normally grow in snow, they contain green plastids, the
cells that appear red because they contain high levels of photoprotective carotenoid
pigments
advantages of asexual reproduction
easy! can replicate without the need to produce gametes or find mates, and causes
rapid population growth during favorable times
advantages of sexual reproduction
increases genetic variability, allowing response to environmental change via evolution,
and helps survive periods of unfavorable growth via tough, resistant structures
asexual reproduction
does NOT involve fusion of gametes or meiosis
cellular bisection
type of asexual reproduction; similar to binary fission, splitting of a single cell into
genetically identical duplicates
zoospores
type of asexual reproduction; flagellate unicells
aplanospores
type of asexual reproduction; non-flagellate unicells that can produce flagella, but didn't
because of unfavorable conditions
autospores
type of asexual reproduction; unicells that lack the genetic capability to produce flagella,
regardless of favorable or unfavorable conditions
autocolony formation
type of asexual reproduction; colonies of defined cell number and shape (coenobia),
produces 'minis' of the original colony (i.e. Volvox)
fragmentation in unicells and filaments
type of asexual reproduction; breaking into pieces and each fragment grows into a new
and identical individual
akinetes
type of asexual reproduction; specialized asexual cells that develop from actively
growing cells when environmental signals indicate conditions unstable for growth (i.e.
winter) common in cyanobacteria
