chlorella
Not considered a cell wall
* Provides rigidity and strength that thhe
membrane cannot offer.
* The exterior protein covering of euglenoids and
the outer proteinaceous covering that protects
and surrounds the cytoplasm.
* Enables flexibility while maintaining the
organism’s form.
pellicle in euglenoids
allow maneuverability and forward movement in dinoflagellates
flagella lying in the cingulum
propel the cell forward in dinoflagellates
flagella lying in the sulcus
Sudden increase or buildup of algae that results
in the discoloration of the water system. These
occur in freshwater, marine (saltwater), and
brackish habitats.
* Causes shellfish poisoning
algal bloom
algal bloom is trigerred by the presence of organic compound like ____ and ____
nitrogen
phosphorous
A specific type of hazardous algal bloom that
causes discoloration of coastal waters, generally
turning them red or brown.
* Created by microorganisms including
phytoplankton such as dinoflagellates and
diatoms.
red tide
the phenomenon in red sea is caused by
algal bloom
Most distinguishing feature is its arm and horns
– vary in shape and size depending on the
species.
* Has 2 flagella that allow the organism to move.
* its morphology is affected by the
temperature and salinity of the surrounding
environment.
* Like the Eiffel tower
ceratium
unicellular organism in K. Protista
green algae that can be
found in freshwater, marine settings, and soil.
* It has 2 flagella of even length
* It has chloroplasts that contain green pigments
* It can produce sexually and asexually.
chlamydomonas
unicellular organism of K. Protista
flagellate eukaryote that many be
found in freshwater and saltwater.
* It has two flagella of uneven length.
* It has chloroplasts that contain, green, yellow,
and brown pigments.
* It can reproduce only asexually
