Sedimentary structure consisting of laminated carbonate or silicate rocks
What type of prokaryotes are found in stromalites?
Is it true that prokaryotes' mass significantly outweighs eukarkyotes?
Able to cause disease
A bacteria, virus, or fungus that takes advantage of certain opportunities to cause disease
What are the three morphologies of bacteria?
Bacilli, Cocci, and Spirochete
Name for the bacteria shape that is rod-shaped or oval
Name for the bacteria shape that is round or spherical
Name for the bacteria shape that is corkscrew or spiral
What are bacterial walls made up of?
Hair like appendages
Conjugation + adherent
Flagella + Cilia
How can prokaryotes withstand harsh conditions?
By forming endospores
A resistant asexual spore that develops inside some bacteria cells; has a thick protective coat
What types of bacteria carry out photosynthesis?
Smaller rings of DNA that carry genes that may provide resistance to antibiotics or metabolize rare nutrients, among other metabolic activities
thin, slimy film of bacteria that adheres to a surface; channels in this allow nutrients and wastes to move inside and outside of it
We get some of our antibiotics from bacteria. What is the major source?
Proteins secreted by bacterial cells
Components of the outer membrane of a gram-negative bacteria, released when the cell dies or is digested by a defensive cell
What causes Lyme's Disease?
What prokaryotes are "hot topics" for biological weapons?
Anthrax, Botulism, the Plague
Using organisms to clean up pollutants
Close association between organisms of two or more species
How do amoeba move?
Pseudopods (false feet)
Eukaryotes with a membrane-bound chromosome, multiple chromosome, flagella or cilia with 9 + 2 pattern of microtubules
Produce own food
Must ingest food
Mutually beneficial association of plant roots and fungi hyphae; enabled plants to colonize land
Seeds develop within protective ovaries
produce seeds in cones
What percentage of our prescription drugs come from plants?
More than 25%
Heterotrophic eukaryotes; digest their food externally and absorb the nutrients
A plant consisting of algae or cyanobacteria within a fungal network
Multicelluar eukaryote, a photoautotroph, making organic molecules by photosynthesis
Subterranean organs (underground)
Aerial leaf-bearing organs (above ground)
Located in leaves of plants, allow for the exchange of carbon dioxide and oxygen with the atmosphere
transport vital materials within a plant
Helps the plant retain water
What are the 4 major groups of plants?
Bryophytes, ferns, gymnosperms, angiosperms
The major group of plants that are non-vascular without lignified walls, true roots, or true leaves. For example: Mosses
The major group of plants that have vascular tissue hardened with lignin, without seeds
The major group of plants that evolve with seeds that consist of an embryo packaged along with a store of food within a protective covering but not enclosed in specialized chambers. For example: Conifers
The major group of plants with complex reproductive structures called flowers that bear seeds within protective chambers called ovaries
Formed from the remains of long-dead organisms; include coal, oil, and natural gas
