chapter 22


along with heterotrophs break Down organic molecules and make them available for recycling fungi
obtain energy by absorbing energy from there surroundings heterotrophic
they have long slender filaments which weave together to form a fungus body Filamentous bodies
the tough material found in the exoskeleton of bugs, they are in the wall of the fungi Walls made of chitin
in a dividing mushroom cell the nuclear envelope remains intact from prophase to anaphase Nuclear mitosis
what are the 4 characteristics of a fungi 1) heterotrophic 2) filamentous bodies 3) Walls made of chitin 4) nuclear mitosis
mold on lime Penicillium
all fungi except yeast have bodies composed of slender filaments called Hyphae Hyphae
when they grow they form a tangled mess called Mycelium Mycelium
each Hyphae is a long string of cells divided by wall septa
fungi digests food outside there body through the tips of the Hyphae, they secrete powerful digestive enzymes that break down the organic matter into smaller molecules, the fungi absorbs these molecules and uses them for energy Food digestion
they like leaves, branches, animal corpses, waste, paper, cardboard, paint, petroleum, bread, fruit, vegetables, and meat Benefits of Fungi food source
the yeast produce Carbon dioxide and ethanol for bread, and wine making Carbon dioxide and ethanol production
in Cheese your smelling the mold Pungent flavors and aromas
it produces the antibiotics main one, Penicillin makes penicillium Antibiotics
drug derived from a fungus that lives in the soil, it suppresses the reactions of the immune system that causes the rejection of transplanted organ cyclosporine
reproduce by releasing spores, the reproductive structures are at the tip of the hyphae, they extent high and the air currents carry them to a new habitat. They land in a suitable place and divide and begun a new mold Fungal Diversity reproduction
what phylum is yeast in phylum Ascomycota
bakers yeast, used in bread and alcoholic beverages Saccharomyces cerevisiae
causes thrush, a disease in milk white legions form on the mouth, lips and throat Candida albicans
Reproduce by budding yeast
what phylum are mushrooms in phylum Basidiomycota
•Basidium •Reproduce sexually phylum Basidiomycota
what phylum is Fungi Imperfecti in phylum Deuteromycota
•Asexual reproductive structures •Penicillium •Aspergillus Fungi Imperfecti
symbiotic association between a fungus and a photosynthetic partner Lichen
provides energy rich compounds for both partners Photosynthetic partner
protects from the environment and provides mineral nutrients Fungal partner
Tough construction of fungus and photosynthetic abilities of plant – can live in the harshest of habitats
sensitive to pollutants linchen
Symbiotic relationship of certain fungi with roots of plants Mycorrhizae
Fungal filaments transfer phosphorus and minerals to roots of plant and plant supplies carbohydrates to fungus Mycorrhizae
formation of a small cell from a larger one budding
named for there characteristic club shaped sexually reproduction structure called the Basidium Basidium
unlike other fungi phylum Reproduce sexually
classified on the basis of there asexual reproductive structures Asexual reproductive structures
produces the antibiotic penicillin Penicillium
used for fermenting soy sauce and for the commercial production of citric acid Aspergillus
athletes foot and ring worm fungi
they live together and both benefit Symbolic
the photosynthetic partner provides energy rich compounds for both partners while the fungi partner provides protection from the environment and nutrients lichens
sensitive to pollutants due to they absorb substances dissolved in rain and dew these compounds then quickly destroy the lichens chlorophyll decreasing the rate of photosynthesis killing the lichen therefore being good indicator of the environments health lichens
tough structure of fungus and the photosynthetic abilities of plants enables the two to endure the harshest of environments such as the artic the desert bare soil tree trunks or sun baked rocks Can survive high drought and freezing by becoming dormant lichens
