Chapter 16 Part 2 Flashcards
Microbiology technique to identify the cell wall composition of bacteria. Results categorize bacteria as positive or negative for the stain.
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. These bacteria are usually less toxic than gram-negative bacteria.
Gram-Positive
A member of a group of photosynthetic protists that includes chlorophytes and charophyceans, the closest living relatives of land plants. This organism includes unicellular, colonial, and multicellular species.
Green-Alga
An organism that cannot make its own organic food molecules and must obtain them by consuming other organisms or their organic products; a consumer or a decomposer in a food chain.
Heterotroph
A type of Archaea that produces gas waste as a metabolic waste product.
Methanogens
Organism that derives its 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; a material unique to bacterial cell walls.
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. Specialized sex is performed using these short projections which are used in conjugation to hold the mating cells together.
Pious
A type of protist that has amoeboid cells, flagellated cells, and an amoeboid feeding stage in its life cycle.
Plasmodia Slime Mold
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
