西瓜种子的结构和类型(要详细点的)

种子虽然在形状、大小、颜色等各方面存在着较大的差异,但其基本结构都是一致的。

都是由胚、胚乳和种皮三部分组成。

  胚是种子中最重要的部分,新的植物体就是由胚生长发育而成的。

胚由胚根、胚芽、胚轴和子叶四部分组成。

  胚根和胚芽的体积很小。

胚根一般为圆锥形,胚芽常具雏叶的形态;胚轴位于胚根和胚芽之间,并与子叶相连,一般很短;依据子叶着生的位置将胚轴分为上胚轴和下胚轴,即子叶着生点至第一片真中之间,称上胚轴,而子叶着生点到胚根之间,称下胚轴。

子叶与一般正常叶的功能是不同的,有储藏养料的作用,或能从胚乳中吸收、转化营养物质供胚生长时使用。

不同种子其子叶数目不同,在被子植物中分为两类:一类具有两片子叶,如瓜类、豆类、棉花、桃、杏、苹果等植物,称之为双子叶植物。

另一类只具有一片子叶,如小麦、玉米、水稻、甘蔗、高粱、百合、葱、蒜、姜等,称之为单子叶植物。

双子叶植物和单子叶植物是被子植物的二个大类,它们不仅在子叶数目上有差别,而且在其他器官的形态结构上也完全相同。

在裸子植物中,子叶数目也很不一致,有两个的如侧柏;有2~3个的如银杏,还有多个的如松树。

  组成胚的细胞都是具有胚性的,这些细胞的特点是体积小,细胞质浓、核相对比较大,细胞质中没有或仅有小的液泡。

当种子萌发时,这些细胞很快分裂,胚根和胚芽突破种皮,胚根发育成幼苗的主根,胚芽发育成茎、叶部分,胚轴发育成茎的一部分,使胚迅速形成幼苗。
