Lesson Seven Fungi: The Great Decomposers
Fungus (pl.fungi or funguses) Fungus [ 5fQN^Es ]n. 菌类, 蘑菇, 真菌 Any of numerous eukaryotic organisms of the kingdom Fungi, which lack chlorophyll and vascular tissue and range in form from a single cell to a body mass of branched filamentous hyphae that often produce specialized fruiting bodies. The kingdom includes the yeasts, molds, smuts( 担子菌 ), and mushrooms.
Any of various leafless, annual parasitic herbs of the genus Cuscuta that lack chlorophyll and have slender, twining, yellow or reddish stems and small whitish flowers. haustorium dodder[ 5dCdE ]vi. 摇摆, 蹒跚 ;n.[ 植 ] 菟丝 子
A Eurasian parasitic shrub (Viscum album) having leathery evergreen leaves and waxy white berries. Mistletoe [ 5misltEu ]n. 槲 寄生
lichen[ 5laikEn ] Thallophyte [ 5WAlEfait ]n. 叶状植物, 菌藻 植物 symbiosis [ simbai5Eusis ]n.[ 生 ] 共生 ( 现 象 ), 合作 ( 或互利, 互依 ) 关系 Any of a group of plantlike organisms showing no differentiation into stem, root, or leaf, including the algae, fungi, and lichens, formerly regarded as constituting a major division of the plant kingdom.
mycelium [ mai5si:liEm ]
The fundamental structure of many fungi is the hypha (plural hyphae), thin threadlike structures; a mass of hyphae is called a mycelium. Many fungi produce a reproductive structure like the common mushroom.
A plant of the Bryophyta, a division of photosynthetic, chiefly terrestrial, nonvascular plants, including the mosses( 苔藓 ), liverworts( 地钱 ), and hornworts( 金鱼藻 ). Bryophyte [ 5braiE7fait ]n. 苔藓类的植 物
Pteridophyte [ 5(p)teridEu7fait ]n. 蕨 类植物 Any of various vascular plants that reproduce by means of spores rather than by seeds, including the ferns( 蕨类植物 ) and related plants, such as club mosses( 石松 ) and horsetails( 木贼属植物 ).
Fungi reproduce using tiny spores. But there can be sexual or asexual reproduction, or both. Note that most of the life cycle of a fungus is haploid. For the test you can ignore the terms plasmogamy, heterokaryotic,and karyogamy. The key feature of fungal reproduction is that tough spores can be formed in either the sexual or asexual part of the life cycle.
