Term
Excavata
Definition
Have 'excavated' grooves on one side of the cell body. Have three Classes:
Diplomonads
Parabasalids
and Two classes of Euglenozoans:
Kinetoplastids and Euglenids
Term
Excavata:Kinetoplastids
Definition
Includes species that feed on prokaryote in freshwater, marine, and most terrestrial ecosystem.
Term
Excavata:Euglenids
Definition
Has a pocket at one end of the cell, many of the specices are MIXTROPHS
Term
Chromalveolata
Definition
include some of the most important photosynthetic organism on earth. Two lines of evidence.
ALVEOLATES:
Dinoflagellates
Apicomplexans
Ciliates
STRAMENOPILES:
Diatoms
Golden algae
Brown algae
Oomycetes
Term
Chromalveolata:Alveolates
Definition
May help stabilize the cell surface or regulate the cell water and iron content.
Dinoflagellates,Apicomplexans, and Ciliates
Term
Chromalveolata:Dinoflagellates
Definition
A group of flagellates
Term
Chromalveolata: Apicomplexans
Definition
A group of Parasites, some of animals and some cause serious human disease.
-Not photosynthetic.
Term
Chromalveolata: Ciliates
Definition
Generally reproduce asexually by binary fission, during which the existing macronucleus disappears and a new one is formed.
Term
Chromalveolata: Stramenopiles
Definition
Stramen- Straw Pilos - Hair
Have fine hairlike characteristic flagellum.
Diatoms, Golden Algae, Brown Algae, Oomyletes
Term
Chromalveolata: Diatoms
Definition
Unicellular algae that have ubique glass-like walls made of hydrated silica embedded into a organic ,matrix.
Term
Chromalveolata: Golden Algae
Definition
Result from the yellow and brown carotenoids are usually biflagellated.
IN fresh water and marine. Usually photosyntheic but some are also mixotrophic.
Term
Chromalveolata:Brown Algae
Definition
The largest and most complex, all are multicellular and most are marine, Cool waters. Ex. Seaweed, Thallus
Term
Chromalveolata: Oomyletes
Definition
The white rust, and the downy mildews. Have cell walls, acquire nutrients as decomposes or parasites. Most water molds are decomposes. White rust and downy live on plants are parasites.
