Prokaryotes + plants Flashcards
(69 cards)
Plasmid
a small ring of independently replicating DNA separate from the main chromosomes. plasmid are found in prokaryotes and yeast.
Endospore
a thick-coat, protective cell produced within a bacterial cell. the endospore becomes dormant and is able to survive harsh environmental conditions.
Endotoxins
a poisonous component of the outer membrane of gram-negative bacteria that is released only when a bacteria dies.
Exotoxins
A poisonous protein that is secreted by certain bacteria.
endosymbiosis
larger cell engulfs a prokaryote smaller cell and both cells benefit from each other (mitochondria + chloroplast).
SAR (Super Group of Protists)
1) Stramenopiles
2) Alveolata
3) Rizaria
Unikonts
A supergroup of protists that is closely related to fungi and animals.
amoebozoans
1) unikonta
2) made of prostist
pseudopodia
moving the cell and engulfing food
cellular slime mold
a type of protist that has unicellular amoeboid calls and aggregated reproductive bodies in its life cycle; it is part of the amoebozoan family.
amoeba
a general term for a protist that moves and feeds by means of pseudopodia (rhizaria)
plasmodium
1) a single mass of cytoplasm containing many nuclei
2) the amoeboid feeding stage in the life cycle of a plasmodial slime molds
plasmodial slime mold
a type of protist that has amoeboid cells, flagellated cells, and an amoeboid plasmodial feeding stage in its life cycle; it is in the amoebozoan family.
charophytes
a group of green algae; closest relative to the plant and lived 500 million years ago.
halophiles
salt lovers
thermophiles
heat lovers
methanogens
archaeans that live in an anaerobic environment and give off methane as a waste product.
proteobacteria
all gram-negative and share a particular rRNA sequence. 1 group of bacteria domain; E. coli
symbiosis
a physical close association between the organism of two or more species
gram-positive bacteria
2 group of domain bacteria; subgroup actinomycetes; streptomyces
cyanobacteria
oxygen-generating photosynthesis; Anabaena
chlamydia
live in eukaryotic host cells; domain bacteria; chlamydia trachomtatis
spirochetes
a member of a group of helical bacteria the spirals through the environment by mean of rotating, internal filaments; treponema pallidum
parasites
drive their nutritional needs from a host, which is harmed by the interaction.
