Chap. 31 Fungi

Campbell Biology Chapter 31 Fungi

QuestionAnswer
Fungi and exoenzymes Fungi are heterotrophs and absorb nutrients from outside of their body. Fungi use enzymes (exoenzymes) to break down a large variety of complex molecules into smaller organic compounds. The versatility of these enzymes contributes to fungi’s ecological
Cellulose and plants, chitin and fungi Plant cell walls contain cellulose, but fungal cell walls are strengthened by chitin. This strong but flexible nitrogen containing polysaccharide is also found in the external skeletons of insects and other arthropods.
Parasites and saprobes The absorptive mode of nutrition is associated with the ecological roles of fungi as decomposers (saprobes), parasites, and mutualistic symbionts.
Hyphae One of many connected filaments that collectively make up the mycelium of a fungus.
Mycelium The densely branched network of hyphae in a fungus.
Septa One of the cross-walls that divide a fungal hypha into cells. (generally have pores large enough to allow ribosomes, mitochondria, and even nuclei to flow from cell to cell
Coenocytic cells They lack septa and consist of a continuous cytoplasmic mass having hundreds or thousands of nuclei.
Ectomycorrhiza Association of a fungus with a plant root system in which the fungus surrounds the roots but does not cause invagination of the host (plant) cells’ plasma membranes.
Endomycorrhiza Fungi extend hyphae through the cell walls of root cells and into tubes formed by invagination of the root cell membrane.
Haustoria In certain symbiotic fungi, a specialized hypha that can penetrate the tissues of host organisms.
Hyphae and pheremones In fungi, sexual reproduction often begins when hyphae from two mycelia release sexual signaling molecule called pheremones.
Plasmogamy The union of the cytoplasms of two parent mycelia.
Facultative, Obligate fungi Facultative Parasite: Heterotroph that is primarily a saprobe, but when opportunity presents itself, can be a parasite. Facultative Saprobe: Heterotroph that is primarily a parasite, but when opportunity presents itself, can become a saprobe. An obligate
Lichens and micorrhizae Lichens are a symbiosis between a photosynthetic organism (an alga or cyanobacterium) and a fungus (either an ascomycete or a basidiomycete).
Dikaryon and karyogamy In some fungi, the haploid nuclei pair off two to a cell, one from each parent. Such a mycelium is dikaryotic (two nuclei). As a dikaryotic mycelium grows, the two nuclei in each cell divide in tandem without fusing. Hours, day, or even centuries pass be
Zygomycetes Member of the fungal phylum Zygomycota, characterized by the formation of a sturdy structure called a zygosporangium during sexual reproduction
Chytrids Member of the fungal phylum Chytridiomycota, mostly aquatic fungi with flagellated zoospores that represent an early-diverging fungal lineage.
Basidiomycetes Member of the fungal phylum Basidiomycota, commonly called club fungus. The name comes from the club-like shape of the basidium.
Ascomycetes Member of the fungal phylum Ascomycota, commonly called sac fungus. The name comes from the saclike structure in which the spores develop.
Pilobolus A zygomycete that can aim and shoot their sporangia toward bright light.
Glomeromycetes Member of the phylum Glomeromycota, characterized by a distinct branching form of mycorrhizae called arbuscular mycorrhizae.
Microsporidia Unicellular parasites of animals and protists closely related to fungi.
Arbuscular mycorrhizae A symbiotic fungus whose hyphae grow through the cell wall of plant roots and extend into the root cell (enclosed in tubes formed by invagination of the root cell plasma membrane).
Lichens and soredia Lichens make soredia to reproduce the lichen body. This is a very fast method of reproduction, and helps insure that the new lichen will survive because both partners are together.

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
