Cards

Term
Protist
Definition
Any organism that is not a plant, an animal, a fungus, or a prokaryote.
Term
Pseudopods
Definition
It's when members of the phylum Sarcodina, or sarcodines, move through temporary cytoplastic projections.
Term
Amoeboid movement
Definition
It's when the cytoplasm of the cell streams into the pseudopod, and the rest of the cell follows.
Term
Food vacuole
Definition
A small cavity in the cytoplasim that temporarily stores food.
Term
Cilia
Definition
Short hair-like projections similar to flagella.
Term
Trichocysts
Definition
Very small, bottle-shaped structures used for defense.
Term
Macronucleus
Definition
A library of genetic information.
Term
Micronucleus
Definition
Contains a "reserve copy" of all of the cell's genes.
Term
Gullet
Definition
An indentation in one side of the organism. Food gets swept into the indentation and is then used for food. (Stores)
Term
Anal pore
Definition
Waste materials are emptied into the environment when the food vacule attaches with a region of the cell membrane.
Term
Contractile vacuoles
Definition
Cavities in the cytoplasim that are specialized to collect water.
Term
Conjugation
Definition
When paramecia are allowed to exchange genetic material with another individual.
Term
Accessory pigments
Definition
Compounds that absorb light at different wavelengths than chlorophyll.
Term
Eyespot
Definition
Near the gullet end of the cell is a cluster of reddish pigment. Helps organisms to find sunlight to then power photosynthesis
Term
Pellicle
Definition
Euglenas do not have cell walls, but they do have an intricate cell membrane called Pellicle.
Term
Phytoplankton
Definition
Constitute the population of small, photosynthetic organisms found near the surface of the ocean.
Term
Phycobilins
Definition
Are especially good at absorbing blue light, enabling red algae to live deeper in the ocean than many other photosynthetic algae.
Term
Filaments
Definition
Spirogyra's long threadlike colonies
Term
Alternation of generations
Definition
When algae switch back from and forth between haploid and diploid stages during their lifecycles.
Term
Gametophytes
Definition
What the Ulva are known as b/c they form gametes.
Term
Spores
Definition
When the diploid Ulva undergoes meiosis to produce haploid reproductive cells.
Term
Sporophyte
Definition
B/c the diploid Ulva produces spores, it's called Sporophyte.
Term
Cellular slime molds
Definition
They are separated by cell membranes-during every phase of the molds life cycle.
Term
Acellular slime molds
Definition
A slime mold that passes through a stage in which their cells fuse to form large cells with many nuclei.
Term
Fruiting body
Definition
A slender reproductive structure that produces spores.
Term
Plasmodia
Definition
When the cells aggregate, their cells fuse to produce structures with many nuclei.
Term
Hyphae
Definition
When water molds produce filaments.
Term
zoosporangia
Definition
It's what asexual reproduction portions of the hyphae develope into.
Term
Antheridium
Definition
Produces male nuclei.
Term
Oogonium
Definition
Produces female nuclei.
Term
Chitin
Definition
It's a complex carbohydrate that is also found in the external skeletons of insects.
Term
Hyphae
Definition
A multicellular fungi are composed of thin filaments.
Term
Mycelium
Definition
The bodies of multicellular fungi are composed of many hyphae tangled together into a thick mass.
Term
Fruiting body
Definition
A reproductive structure growing from the mycelium in the soil beneath it.
Term
Sprangia
Definition
Spores that are produced.
Term
Sporangiophores
Definition
Where the sporangia are found at the tips of specialized hypae.
Term
Zygospore
Definition
A resting spore that contains zygotes formed during the sexual phase of the mold's life cycle.
Term
Rhizoids
Definition
The rootlike Hyphae that penetrate the breads surface.
Term
Stolons
Definition
The stem-like hyphae that run along the surface of the bread.
Term
Gametangia
Definition
When mold's sexual phase begins when hyphae from different mating types fuse to produce gamete-forming structures.
Term
Conidia
Definition
Tiny spores that are formed at the tips of specialized hyphae called conidiophores.
Term
Ascus
Definition
Forms within the fruiting body.
Term
Ascospores
Definition
eight cells are produced during a cycle of mitosis
Term
budding
Definition
asexual reproduction as seen in rapidly growing yeast cells
Term
basidium
Definition
club fungi that gets its name from a specialized reproductive structure that resembles a club. It is a spore-bearing structure and are found on the gills that grow on the underside of mushroom caps.
Term
basidium
Definition
club fungi that gets its name from a specialized reproductive structure that resembles a club. It is a spore-bearing structure and are found on the gills that grow on the underside of mushroom caps.
Term
basidiospores
Definition
Mushroom caps have tiny gills lines with basidia. The two nuclei in each basidium fuse to form a diploid zygote cell which undergoes meiosis, which forms clusters of haploid basidiospores.
Term
lichens
Definition
Symbiotic associations between a fungus and a photosynthetic organism. They are not single organisms. They are extremely resistant to drought and cold. They can grow therefore in places where few other organisms can survive like dry, bare rock in deserts and on the top of mountains.

Term
mycorrhizae
Definition
An association with plant roots and fungi
Term
saprobes
Definition
fungi that obtains food from decaying organic matter
