Chap 11 Microbio (1)

A parasite that invades an organism other than its normal host

Major group of protozoans which move by pseudopodia and ingest food by phagocytosis

Asexual part of the life cycle of a fungus.

The natural production of an antimicrobial agent by a bacterium or fungus.

also called sporozoan

a parasitic proozoan such as Plasmodium, that generally has a complex life cycle.

An anthropod with two body regions, for pairs of legs, and mouth parts that are used in capturing and tearing apart prey.

Makes up the largest group of living organisms, characterized by a jointed chitinous exoskeleton, segmented body, and jointed appendages associated with some or all of the segments

Sac Fungus

A member of a diverse group of fungi that produces saclike asci during sexual reproduction.

One of the eight sexual spores produced in each ascues of a sac fungus.

Saclike structures produced by sac fungi during sexual reproduction

club fungus

A sexual spore of the club fungi

a clublike structure in club fungi bearing four external spores on short, slender stalks

An organism that actively transmits pathogens that complete part of their life cycle within the orgainsm.

A fungus with complex mycelia composed of aseptate hyphae with chitinous cross walls

Funguslike protist consisting of amoeboid, phagocytic cells that aggregate to form a pseudoplasmodium

A free-swimming fluke larva that emerges from the snall or mollusk host

A polysaccharide found in the cell walls of most fungi and the exoskeletons of athropods.

A protozoan that moves by means of cilia that covers most of its surface.

A fungus, including mushrooms, toadstools, rusts, and smuts, that produces spores on basidia

The body cavity between the digestive tract and body wall in higher animals

An organism that lives in or on another organism without harming it and that benefits from the relationship.

a small, asexual, aerial spore organized into chains in some bacteria and fungi

the exchange of information between two ciliates (protists)

a usually aquatic athropod that has a pair of appendages associated with each body segment.

bladder worm

an oval white sac with a tapeworm head invaginated into it.

An organism that harbors the adult, sexually reproducing form of a parasite.

Fungi Imperfecti

An alga or plantlike protist that lacks flagella and has a glasslike outer shell

referring to fungal cells within hyphae that have nuclei, produced by plasmogamy in which the nuclei have not united.

the ability of an organism to alter its structure when it changes habitats

an alga or plantlike protist, usually with two flagella

A parasite that lives on the surface of another organism

an alga or plantlike protist, usually with a single flagella and a pigmented eyespot (stigma)

The nutrient enrichment of water from detergents, fertilizers, and animal manures, which causes overgowth of algae and subsequent depletion of oxygen.

A parasite that can live either on a host or freely

(also called Platyhelminthes)

A premitive, unsegmented, hermaphroditic othen parasitic worm

A flatworm with a complex life cycle, can be an internal or external parasite.

The kingdom of nonphotosynthetic, eukaryotic organisms that absorb nutrients from their environment

also called Deuteromycota

Group of fungi termed "imperfect" because no sexual stage has been obsered in their life cycles.

a male or female sex cell

a worm, with bilateral symmetry; includes the roundworms and flatworms

having both male and female reproductive systems in one organism

any organism that harbors another organism

the range of different hosts in which a parasite can mature

An enlarged cyst containing many tapeworm heads

the phenomenon of a parasite itself having parasites

A long, threadlike structure of cells in fungi or actinomycetes

An arthropod with three body regions, three pairs of legs, and highly specialized mouthparts
