viral DNA combines into the host DNA, the viral DNA is replcated, then the prophage may leave the host DNA and enter the lytic cycle; is replicated along with the host cell's DNA
a virus that infects bacteria
a method of viral replication that results in the destruction of a host cell and the release of many new virus particles; causes cell to burst
a nonliving, infectious particle composed of a nucleic acid and a protein coat; it can invade and destroy a cell; that replicate only by infecting living cells
a membrane-like layer that covers the capsids of some viruses
A protein sheath? that surrounds the nucleic acid core in a virus
resting cell that forms inside a bacterial cell; has/ protects DNA in the cytoplasm; must heat under high pressure to kill
long, thin, whip-like structures, with a core of microtubules, that enable some cells to move
a short, thick hair-like protein structure that allows a bacterium to attach to other bacteria and surfaces
for bacteria, a form of asexual reproduction in which one cell divides to form two identical cells.
in algae and fungi, an exchange of genetic material that occurs between two temporarily joined cells; a form of sexual reproduction; in which paramecia and some prokaryotes exchange genetic information
in mosses, the part that contains spores; in bacteria, a protective layer of polysaccharides around the cell wall
it doesnt have a metabolism or enzymes to make protiens
Why is a virus non-living?
a virus invades the host cell, produces new virus, destroys host cell, & then releases new virus
What happens in the lytic cycle?
virus that contains RNA as its genetic information
single-celled organisms that lack a nucleus; prokaryotes; smallest and simplest organism on the planet
capsule, cell wall, cell membrane, cytoplasma, chromosome, pilus, flagellum, outer membrane
What is the structure of bacteria
envelope, nuclear membrane, cell membrane, capsid

agriculture, medicine, food, recycling
industries that use bacteria
live in marshes, lakes, sediments, lower GI tract, salt lakes, sulfur springs; used at sewage disposal plants
live in hospitable places; vary in nutritional needs
both, hetero & auto(photo & chemo)
eubacteria- auto or heterotrophic
types of protozoans:
types of algae
The stage in the life cycle of a plant in which the plant produces spores., The multicellular diploid form in organisms undergoing alternation of generations that results from a union of gametes and that meiotically produces haploid spores that grow into the gametophyte generation.
the gamete-producing individual or phase in the life cycle of a plant having alternation of generations
funguslike protists that play key roles in recycling organic material
most are small, single- celled organism. live in water, moist soil, or other organisms; eat animals
cause many plants diseases
organisms which get their energy by breaking down dead organisms and the wastes of living organisms; & turn food into inorganic material
cell walls are made of chitin/ don't move; Plantlike organism that lacks chlorophyll; 20- 30 degrees C; multi, some unicellular
branching, threadlike tubes that make up the bodies of multicellular fungi
a mat of hyphae that forms the body of a fungus
a tough semitransparent horny substance; contained in fungus
the cells that make up hyphae are divided by these cross sections
the process in which enzymes are secreted to digest food outside the organism
fungi that feed on dead matter, Organisms that obtain their food from dead organic matter (plant and animal material)
fungi that live interdependently with photosynthetic organisms, both benefit
In parasitic fungi, a nutrient-absorbing hyphal tip that penetrates the tissues of the host but remains outside the host cell membranes.
A means of asexual reproduction whereby a single parent breaks into parts
asexual reproduction in which a part of the parent organism pinches off and forms a new organism
reproductive cells that form without fertilization
black bread mold
prod spores called zygospores
Club-shaped structures on the underside of club fungi where spores form.
