1 Lesson Seven Fungi: The Great Decomposers

2 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.

3 Ascomycetes [ 7AskEumai5si:ti:z ] ascus [ 5AskEs ] (pl. asci[ 5Asai ]) ( 微生物 ) 子囊 plasmogamy [ plAz5mC^Emi ] n.[ 生 ] 胞质融合, 胞质配合 -mycete suff. (后缀)真菌类

4 Basidiocarp -carp suff. (后缀) suffix Fruit; part of a fruit; fruitlike structure: 果实; 部分果实;似果实的结构: mesocarp. 中果皮

5 Ascocarp (子囊果)

6 Basidium (pl.basidia) Basidiospore [ bE5sidiEuspC: ]n.[ 植 ] 担子孢子 Amanita [ 7AmE5naitE ] n.[ 植 ] 伞形毒 菌 Basidiomycete [ bE7sidiEumai5si:t ] n. 担子菌类

7 Conidium [ kEu5nidiEm ]n. 分生孢 子子实体 pl. conidia septum (pl. septa) [ 5septEm ] n.[ 生 ] 隔膜

8 Conidiospore [ kEu5nidiEspC :] n. 无性孢子, 分生孢子

9 gametangium antheridium[ 7AnWE5ridiEm ]n. 孢子囊,精子囊 oogonium[ 7EuE5^EuniEm ]n.[ 生 ] 卵原细胞, 雌 性生殖结构 oo- pref.( 前缀 )Egg; ovum: 蛋,卵 ; oogenesis; 卵生成 archegonium[ 9B:kI`^EJnIEm ]n. [ 植 ]( 雌性 器官 ) 藏卵器 archi- 或 arch- pref. (前缀) Chief; highest; most important: 主要的;最高的;最重 要的: archiepiscopal. 大主教的 Earlier; primitive: 早期的;原始的: archenteron. 原肠

10 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

11 A Eurasian parasitic shrub (Viscum album) having leathery evergreen leaves and waxy white berries. Mistletoe [ 5misltEu ]n. 槲 寄生

12 heterokaryon[ 9hetErEJ `kArICn ] hetero- 表示 “ 其他的, 不同的, 异 ” 之义 ( 元音 之前作 heter-) heterochromatic 杂色的 ; heterocyclic 杂环化合物的 kary(o)- 表示 “ 细胞核 ” 之义 karyogamy 核融合,核配合

13 hypha [ 5haifE ] (pl. hyphae)

14 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.

15 mycelium [ mai5si:liEm ]

16 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.

17 rhizoid[ `raIzRId ] gametophyte [ ^E5mi:tE7fait ]n.[ 植 ] 配子体 -phyte suff. (后缀)表示 “ 具有某一特定特征或 生长地的植物 ” : Halophyte 盐土植物 mycorrhizal myco- 或 myc- (前缀)真菌: mycology. 真菌学

18 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

19 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 ).

20 saprobe[ 5sAprEub ] saprophyte [ 5sAprEufait ]n. 腐生物, 腐生菌

21 spore [ spC: ]n. 孢子 ;vi. 长孢子 sporangium

22 Text

23 truffle

24 penicillium

25 mushroom

26 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.
