Algae Flashcards
described as photoautotrophs that lack the roots and stems of plants
ALGAE
Much of the worldâs petroleum was formed from ____ and other ________ organisms that lived several million years ago.
diatoms, planktonic
The body of a multicellular alga
thallus
anchors the alga to a rock
Holdfasts
stem-like and often hollow
Stipes
a floating, gas-filled bladder found on brown seaweed
pneumatocyst
a (a light-trapping pigment) and accessory pigments involved in photosynthesis are responsible for the distinctive colors of many algae
Chlorophyll
Most algae are photosynthetic; except for the fungal-like algae called
Oomycotes, which are chemoheterotrophs
a thickener used in many foods (such as ice cream and cake decorations), stabilizer, and emulsifier
ALGIN
a brown algae that induce vaginal dilation before surgical entry into the uterus through the vagina
Laminaria japonica
the kelpâs storage material made of
carbohydrates which is extracted from their cell wall
ALGIN
encourage suspension of one liquid in another, similarly in the mixture of oil and water
Emulsifier
Delicately branched thalli and can live at greater ocean depths than other algae due to the red pigments that allow them to absorb blue light
Red algae
Agar used in many microbiological media is from?
Red algae
a gelatinous material that comes from Irish moss.
CARRAGEENAN
Where does carrageenan come from?
Irish moss
thickening agent in evaporated milk
ice cream, and pharmaceutical agents.
AGAR and CARRAGEENAN
algae with cellulose cell walls containing chlorophyll A and B, and store starch, as plants do
Green algae
It is yellow-green in color and is known as accessory pigment as it absorbs energy of different wavelengths and transfer it by resonance to chlorophyll-a.
Chlorophyll B
It is blue-green in color and is known as essential pigment for it can absorb and convert light energy into chemical energy
Chlorophyll A
Unicellular or filamentous algae with complex cell walls that consist of pectin and a layer of silica
DIATOMS
Diatoms store energy captured through photosynthesis in the form of ?
oil
It is produced by diatom causing mussel poisoning leading to outbreak of a neurological disease in Canada
Domoic acid toxin
Unicellular algae collectively called plankton, or free-floating organisms.
DINOFLAGELLATES
the algae trapped in the gills of the fish that release a neurotoxin that stops the fish from breathing.
Karenia brevis
It produces saxitoxin that causes paralytic shellfish poisoning.
Alexandrium (genus)
a toxin that causes paralytic shellfish poisoning.
saxitoxin
a potentially fatal syndrome resulting from the ingestion of one or more of a family of potent neurotoxins called saxitoxins
Paralytic shellfish poisoning (PSP)
Gives the ocean a deep red color thus the name RED TIDE originates
DINOFLAGELLATES
Alexandrium (genus) or Karenia brevis
responsible for periodic massive fish deaths along the Atlantic Coast.
Pfiesteria
an illness caused by eating fish that contain toxins produced by a marine microalgae called Gambierdiscus toxicus
Ciguatera fish poisoning (or ciguatera)
Ciguatera fish poisoning (or ciguatera) is an illness caused by eating fish that contain toxins produced by a marine microalgae called
Gambierdiscus toxicus
Decomposers that form the cottony masses on dead algae and animals, usually in fresh water
WATER MOLDS/OOMYCOTA
spores of oomycote, has two flagella
Zoospores
infects soy beans, potato, and cocoa
Phytophthora
