Cards

Term
Excavates
Definition
Lack mitochondira, move by flagella. Use glycosis for energy. Diplomonadid and Parabasala.
Term
Diplomonadida
Definition
Two nuclei. No golgi complex.
Term
Parabasala
Definition
Fin called an undulating membrane.
Term
Discicristates
Definition
(Eugenoids, Kineotoplastids, Aliveolates) Disc-shaped inner mitochondrial membranes. Highly motile. Protozoa.
Term
Eugenoids
Definition
Freshwater, auto and hetero. Profuse organelles. Spirally grooved pellicle instead of cell wall. Two flagella.
Term
Kineotoplastids
Definition
nonphotosynthetic, heterotrophic cells that live as parasites. single mitochondrion with a kinetoplastid. Two flagella.
Term
Aliveolates
Definition
(Ciliophora, Dinoglagellata, Apicomplexa) small, membrane-bound vesicles called alveoli.
Term
Ciliophora
Definition
motile. swim by cilia. highly developed organelles. Micro/macronucleus. Conjugation reproduction.
Term
Dinoflagellata
Definition
motile, shell formed from cellulose plates. Bioluminescent (flash) and red tides. most marine phytoplankton.
Term
Apicomplexa
Definition
nonmotile, parasitic. absorb nutrients through their membranes. no vacuoles.
Term
Heterokonts
Definition
(Oomycota, Bacillariophyta, Chrysophyta, Phaeophyta) Two different flagella -- hairy one and plain one. Flagella only on reproductive cells EXCEPT golden algae.
Term
Oomycota
Definition
Funguslike, no chloroplasts, heterotrophs.
Term
Bacillariophyta
Definition
Glassy silica shell. Autotrophs, similar pathways to plants.
Term
Chrysophyta
Definition
Color due to fucoxanthin. Retain flagella.
Term
Phaeophyta
Definition
Brown algae. Photosynthetic autotrops. Marine. Complicated reproductive cycles.
Term
Cercozoa
Definition
(Radiolara, Foraminifera, Chlorarachinophyta) Move by pseudopods.
Term
Radiolaria
Definition
Heterotroph. Acopods -- slender, raylikke strands of cytoplasm.
Term
Foraminifera
Definition
Shells of organic matter. Heterotrophs.
Term
Chlorarachinophyta
Definition
Photosynthetic autotrophs. Green, also engulf food.
Term
Amoebozoa
Definition
(Amoebas and 2 slime molds) Pseudopods for locomotion and feeding.
Term
Amoebas
Definition
lobose pseudopod, unsupported by internal cellular organization. no fixed body shape.
Term
Cellular Slime Molds
Definition
individual cells. fruiting body.
Term
Plasmodial Slime Molds
Definition
large composite mass. plasmodium -- individual nuclei are suspended in a common cytoplasm surrounded by a single plasma membrane. fruiting body.
Term
Opisthokonts
Definition
(spawned Fungi and Animals and Choanoflagellates) single posterior flagellum at some stage in the life cycle of these organisms (sperm)
Term
Choanoflagellata
Definition
Collar of closely packed microvilli that surrounds the single flagellum. upside down lampshade.
Term
Archaeplastida
Definition
(spawned Viridaeplanta -- Land Plants) Also Rhodophyta and Chlorophyta.
Term
Rhodophyta (Red Algae)
Definition
small marine seaweeds. free-living autotrophs (usually).
Term
Chlorophyta (Green Algae)
Definition
Photosynthesis, like plants. Most are microscopic, some are seaweeds. little difference with brown algae.
