Vocabulary Chapter 16 Pt 2 Flashcards
Microbiology technique to identify the cell wall composition of bacteria
Gram stain
The multicellular haploid form in the life cycle of organisms undergoing alternation of generations; mitotically produces haploid gametes that unite and grow into the sporophyte generation
Gametophyte
Diverse group of bacteria with a cell wall that is structurally less complex and contains more peptidoglycan than that of gram-negative bacteria
Gram-positive
A member of a group of photosynthetic protists that includes chlorophytes and charophyceans
Green alga
An organism that cannot make its own organic food molecules and must obtain them by consuming other organisms or their organic products
Heterotroph
A type of archaea that produces gas waste as a metabolic waste product
Methanogen
Organism that derives it’s nutrition from a living host, which is harmed by the interaction
Parasite
An agent such as a virus, bacteria, or fungus that causes disease
Pathogen
A polymer of complex sugars cross-linked by short polypeptides
Peptidoglycan
An organism that obtains energy from sunlight and carbon from co2 by photosynthesis
Photoautotroph
An organism that obtains energy from sunlight and carbon from organic sources
Photoheterotroph
A short projection on the surface of a prokaryotic cell that helps the prokaryote attach to other surfaces
Pilus / Pili
A type of protist that has amoeboid cells, flagellated cells, and an amoeboid feeding stage in its life cycle
Plasmodia slime mold
(1)A single mass of cytoplasm containing many nuclei. (2) the amoeboid feeding stage in the life cycle of a slime mold
Plasmodium
A diverse clade of gram-negative bacteria that includes five subgroups known as alpha, beta, gamma, delta, and epsilon
Proteobacteria
A member of the kingdom in which it is named
Protist
A protist that lives primarily by ingesting food
Protozoan / Protozoa
A temporary extension of an amoeboid cell
Pseudopodium / pseudopodia
A protist that moves and feeds by means of threadlike pseudopodia and has a mineralized support structure composed of silica
Radiolarian
A member of a group of marine, mostly multicellular, autotrophic protists, which includes the reef-breeding coralline algae
Red alga
A process by which protist diversity is hypothesized to have evolved from a symbiotic association that arose when an autotrophic eukaryotic protist was engulfed by a heterotrophic eukaryotic protist
Secondary endosymbiosis
A member of a group of helical bacteria that spiral through the environment by means of rotating, internal filaments
Spirochete
The multicellular diploid form in the life cycle of organisms undergoing alternation of generations
Sporophyte
A close association between organisms of two or more species
Symbiosis
