| 1. | Most monocotyledons are hypogeal . 大部分单子叶植物都是地面下的。 |
| 2. | In a monocotyledonous plant, the same role is played by the scutellum, as in a cereal grain . 在一个单子叶植物中,同样的作用由盾片来承担,如在一个谷粒中。 |
| 3. | A cladistic analysis of monocotyledons at the family level based on morphological data 单子叶植物科级分类阶元形态性状分支分析 |
| 4. | Dicotyledons usually show a netlike arrangement whereas monocotyledons generally show a parallel distribution of vein 双子叶植物主要为网状脉,而单子叶植物主要为平行脉。 |
| 5. | The origin and radiation of angiosperms ( flowering plants ) have long been important issues attracting botanists 因此,对研究被子植物(有花植物)的起源与演化以及单子叶植物的起源具有重要价值。 |
| 6. | Some 60 of monocotyledons and 40 of dicotyledons are polyploid , as are 90 of ferns , many bryophytes , and some algae 60的单子叶植物和40的双子叶植物、 90的蕨类植物、多数苔藓植物以及某些藻类,都是多倍体。 |
| 7. | Angiosperms are divided into two major classes , the monocotyledons ( monocotyledonae ) and dicotyledons ( dicotyledonae ) , with a small basal group known as primitive dicotyledons 被子植物可以划分为两个纲,单子叶植物纲和双子叶植物纲。 |
| 8. | Monocotyledons and dicotyledons are so termed because they normally conatin one and two cotyledons respectively although there are exceptions 尽管有例外的情况出现,我们通常还是根据子叶的数目为一片还是两片而把植物分成单子叶植物和双子叶植物。 |
| 9. | The results of this study support removing acorus from araceae as a singular family and as the basal and relative isolation of the monocotyledon . 2 据此认为菖蒲属应从天南星科中分出并单独成科;同时支持菖蒲属位于单子叶植物基部较孤立的系统地位。 |
| 10. | Juncaceae ( rushes ) a family of monocotyledonous plants , mostly herbs , with long , narrow grasslike or cylindrical leaves spirally arranged , but usually arising close to the ground 灯芯草科(灯芯草属) ) :单子叶植物的一个科,多为草本,狭长扁平或柱状的叶呈螺旋状排列,通常簇生。 |
