Cards

Term
Endosymbiotic Theory
Definition
Origin of mitochondria and chloroplasts in protists
Term
Endosymbiosis
Definition
Aerobic bacterium eaten by anaerobic eukaryote
Term
secondary endosymbiosis
Definition
Protist ate photosynthetic protist
Term
How do mitochondria replicate?
Definition
By binary fission! Not in mitosis and stuff
Term
why is mitochondria replication
Definition
70s ribosomes choroplast with peptidoglycan cell wall
Term
Genetic Meiosis
Definition
organism is diploid, meiosis makes gametes
Term
Sporic meiosis
Definition
alternating haploid or diploid individuals
meiosis makes spores
Term
Zygotic meiosis
Definition
organism haploid meiosis occurs in zygote
Term
Amoebozoa
Definition
Lack cell wall
Ingest food via phagocytosis (engulf)
Decomposes
Term
Division Myxomycota
Amoebozoa
Definition
plasmodial slime mold
Giant multinucleate cell, one cell lots o nucleauses.
Bright colors, not photosynthetic
Gametic Symbiosis, 2n when bad goes to spores
Term
Division Dictyostelida
Amoebozoa
Definition
Feed as single amoeboid cell
SLUG ONE
NO flagellated stage (unusual)
Term
Division Rhizopoda
Amoebozoa
Definition
Single cell
move with psuedopodia (crawl)
Aquatic + marine
Amoebic disentary
Term
Kingdom Excavata
Definition
Usually asexually reproducting
unique feeding grove
unicellular
Term
Division Diplomonadida
Kingdom Excavata
Definition
Anaerobic (No mitochondria)
Have 2 nuclei!!

Term
Division Euglendia
Kingdom Excavata
Definition
Disc shaped cristase in mitochondria
Photosynthetic and consume prey
Pellicle internal structure
Term
Phylum Kinetoplastida
Kingdom Excavata

Definition
Have alveoli (small membrane cavities under cell surface)
Tubular Cristae in Mitochondria
Single celled
Move with flagella or cilia
Term
Phylum Cilophara

Subkingtom Alveolata
Definition
Most Complex Cell
Many Cilia
Have 2 nuclei
Macronucleus - polyploid, everyday stuff
Micronucleus - meiotic, for meiosis
