释义 |
低等植物dīděng zhíwù一般指构造简单,无茎叶分化,生殖细胞多为单细胞结构的植物。旧时的低等植物范围较大,包括苔藓类和蕨类植物。现在以胚的有无作为区分高等植物与低等植物的标准。{lower plant; plant with simple structure, no differentiation of stems and leaves, and germinating from a single cell. In the past, lower plant forms covered a wider range, including bryophytes and pteridophytes, but now the standard to differentiate higher and lower plants is based on whether or not they have embryos.} |
