Protista Flashcards
How do Eukaryotic Cells Differ from Prokaryotes?
Cytoskeleton and Compartmentalization
What is Endosymbiosis supported by?
DNA inside Chloroplast and Mitochondria
What defines Protists?
Not Animals, plants, or fungi, everything else, Junk Drawer.
What is a Cysts?
Used for disease transmission, resistant outer covering, Dormant.
Locomotion
Flagella, Cilia, Pseudopodia(False Feet) - Lobopods, Filopods, Axopods.
What reproduction type do Protists use?
Asexuel commonly, Sexual under stress.
What types of Mitosis do protists use?
Mitosis- 2 equal daughter cells, Budding- 1 daughter cell is smaller, Schizogony- division produced by nuclear division, produces multiple offspring.
What is Excavata
A Kingdom section with Diplomonads, paraboloids, and euglenozoans.
What are Diplomonads
Unicellular, move with flagella, 2 nuclei, Degenerate Mitochondria
Parabasalids
Live in guts of termites, Locomotion- Undulating Membrane, Use Flagella, no Mitochondria
Euglenozoa
Mitochondria, 1/3 have chloroplasts, all have pellicle (flexible), only asexual Repro
What are the characteristics of Euglena?
2 Anterior, unequal flagella, collects water with Contractile Vacuoles, Stigma, Tiny Chloroplasts.
What are Kinetoplasts
2nd major Euglenozoa, single Mitochondrion- Diseases- African Sleeping Sickness. Frequently change protective coat
Chromalveolata
2 Kingdom Branches, Alveolates and stramenoplia,
What Dinoflagellates
Have Flagella, Photosynthetic, unicellular , aquatic, can be Luminescent
