Algae that floats in water via flagella are called
benthic
Algae that are attached to substratum and living bottom are called ________. They are also plant-like in appearance and they are dominant primary producers in many shallow lakes and
streams.
light and moisture
twocharacteristics that algae loves
Littoral zone
Where algae normally are: near shore area;
light penetrates
all the way to the
sediment
thin and rigid
Descriptions of algae's cell wall which contains the following:
Part of the algae that carries photosyntheticpigments, pyrenoids, and eyespot or stigma
Chlamydomonas
a genus of unicellular photosynthetic flagellates, is an important model for
studies of such fundamental processes as photosynthesis, motility, responses to stimuli such as
light, and cell-cell recognition.
Chlorophyll, carotenoids, phycobilins
Pigments found in algae
Chlorophyll
green photosynthetic pigment found in plants, algae, and cyanobacteria
Carotene
orange photosynthetic pigment important for photosynthesis. It contributes to photosynthesis by transmitting the light energy it absorbs to chlorophyll
phycobilins
Are especially efficient at absorbing red, orange, yellow and green light,
wavelengths which are not well absorbed by chlorophyll a.
Phycoerythrobilin
red
Phycourobilin
orange
Phycoviolobilin
violet
Phycocyanobilin or phycobiliverdin
blue
yellow/red phycobilins
Organisms growing in shallow waters
tend to contain ________
green phycobilin
Organisms growing at greater depth often contain more of __________
Flagella
locomotive organelle used by algae which moves the cell through an aqueous environment the
flagellar apparatus reacts to the mechanical, chemical, gravitational and light stimulation of the cell.
It also plays an important role during sexual fusion of isogamous, anisogamous and
oogamous species of green algae.
Binary fission and fragmentation
Asexual reproduction types of algae
Conjugation
Sexualreproduction processes of algae
Antheridia
Male structure of algae that produces sperm
Oogonia
Female structure of algae that forms the eggs
isogamy, heterogamy, oogamy
Sexual reproduction processes of algae
isogamy
happen if the sexual cells, or gametes, are of the same form and size and are usually indistinguishable from each other
heterogamy
state or condition in which
conjugating gametes are dissimilar in structure and size as well as in function
oogamy
when
the gametes also have different mobility (non-motile female and motile male)
Phytoplankton
are primary producer for organism in aquatic ecosystem
70%
Algae (phytoplankton) is responsible for
the production of approximately _______ of the oxygen and organic matter in aquatic
environments.
Chlorella
Important source of food and food supplement that improve the
nutritional quality of a daily diet; single-cell protein
Caulerpalentillifera
Species of green algae from coastal regions in the Indo-
Pacific. This seaweed is one of the favored species of edible Caulerpa due to its soft and
succulent texture.
lato or arosep
Local name of caulerpa
Palmaria palmata
Grows on north-facing cliffs and shady crevices.
The blood red plants is rich
in potassium, iron, iodine and trace elements and all kinds of Vitamins.
Dulse
other name for Palmaria palmata
Poryphyra
Specie of red alga that is cultivated in japan, china, and korea as seaweed known as nori or zicai
Gracilaria and Gelidium
Are genera of red algae (Rhodophyta) notable for its economic
importance as an agarophyte
True
True or false: Algae are source of agar, agarose, and carrageenan which are solidifying agents used in
