Chapter 2 Morphology,structure and physiological function of eukaryotes
真核细胞 Definition: eukaryotic cells are com partmentalized by membran es. The cell contains several different ty pes of membrane bou-nd organelle in which different biochemical and physiological processes can occur in a regulated way. Mem branes also transport information, metabolic intermediats and end-products from the site of biosynthesis to the site of use 真核生物 Eukaryotes is a big group of living organisms made up of eukaryotic cells with mem brane bound nucleus and several organelles such as mitochondrion etal. and divided by mitosis.真核生 物是一大类细胞核具有核膜,能进行有丝分裂,细胞质中存在线粒体或同时存在叶绿体等 多种细胞器的生物. 真核微生物 eukaryotic micro-organisms is a group of Microorganisms that made up of eukaryotic cells include Fungi, microalgae ( and protozoa

真菌是最重要的真核微生物,故是本章的重点,它们 的特点是: ①无叶绿素,不能进行光合作用; ②-般具有发达的菌丝体; ③细胞壁多数含几丁质; ④营养方式为异养吸收型; ⑤以产生大量无性和(或有性孢子的方式进行繁殖; ⑥陆生性较强
