真菌是低等植物的一个门,少数为单细胞,绝大多数是由单排细胞所组成的分枝或不分枝菌系所组成,有隔或无隔。菌丝交织在一起组成的生物体称菌丝体(营养体)。有些菌丝平行结合成绳索状叫菌素。真菌植物体无色,细胞无叶绿素是异养植物多为寄生或腐生,一般都有细胞壁。真菌所贮藏的营养物质是肝糖、油脂和菌蛋白等,而不含淀粉,真菌生殖分有性和无性两种。真菌有七万多种,分布极广,在土壤中最多,寄生或腐生在各动植物遗体上。 Fungi is a door to lower plants, a small number of single cells, the vast majority of single-row cells consisting of branches or non-mycobacterial lines, with or without septum. Mycelia intertwined with the composition of the organism called mycelium (nutrition). Some mycelium parallel combination of rope-like terramycin. Fungal plants colorless, chlorophyll-free cells are mostly heterotrophic parasitic or saprophytic, generally have cell walls. Fungi stored nutrients are glycogen, oil and protein, etc., without starch, fungal genital sexual and asexual two. There are more than 70,000 fungi, widely distributed in the soil most, parasitic or saprophytic in the body of animals and plants.
