Hetrotrophic
Two examples of Protozoa ?
Amoeba and flasmodium
What kingdom does algae fall under?
Protists
Is algae plant or animal like ?
Plant like
Is algae unicellular or multicellular
Both
Is algae Hetrotrophic or autotrophic ?
Autotrophic
Three colours algae can be ? And three examples ( of the multicellular type )
Red, brown or green algae . Diatoms , euglena , dinoflagellates
Three characteristics of slime and water module ?
Fungus-like , multicellular, Hetrotrophic
Can algae photosynthesis and why?
Yes , it contains chloroplasts
What are the locomotory structures of slime and water mound algae ?
Pseudopodia , cilia , flangella
When Protozoa ingests food is it called.
Phagocytosis
Why is some algae green?
The cell walls are made of cellulose
Diatoms cell walls made of ? And what appearance does it have?
Made of silica and shiny appearance
Are all protists eukaryotic or prokaryotic?
Eukaryotic
Protists way of reproduction ?
Asexually by binary fission but some algae is sexual
Where are protists found ?
Water environment mostly
What is plankton ?
Numerous microbes floating in currents of open seas
What is the animal part of plankton called ?
Zooplankton
What is the plant part of plankton called ?
Phytoplankton
What are the five importance of algae ?
1) producers food ( phytoplankton)
2) releases O2
3) provides habitat- kelp bed
4) indicates fresh water
- very polluted ( euglena)
- less polluted ( blue- green algae)
- barely polluted ( very green algae)
5) harvested as fertilizer
What type of algae is found in very polluted water?
Euglena
What type of algae is found is barely polluted water ?
Green algae
What type of algae is found is less polluted water ?
Blue- green algae
Euglena does is contain chlorophyll?
Yes
Euglena- autotrophic or Hetrotrophic?
Autotrophic
What happens in Euglena is kept in the dark.
It looses its chlorophyll and becomes saprophytic
What division is euglena placed in?
Euglenoids
Does a euglena have a cell wall , and of not , what replaces it ?
It does not have a cell wall but instead and flexible pellicle just below the cell membrane
What is a pellicle ?
A protein coat
What is red tide ?
It occurs because of upwelling . Dormant spores of dinoflagellates which sank to bottom of sea last summer are brought to didactic with nutrient -rich water . Spores germinate and reproduce ( favorable conditions)
