问题 填空题

植物有那五种组织:______;______;______;______;______.导管属于那种组织______.人体有那四种组织______;______;______;______;血液属于那种组织______.非生物因素有哪些______;______;______;______;______.

答案

植物的组织主要有:分生(基本)组织、保护组织、营养组织、输导组织、机械组织等,分生(基本)组织具有很强的分裂能力,不断分裂产生新细胞形成其它组织,如根尖的分生区、茎的形成层等属于分生组织.保护组织一般由植物根、茎、叶表面的表皮细胞构成,位于植物体的最外面,具有保护内部柔嫩部分的功能.输导组织有运输物质的作用,如贯穿于根、茎、叶等处的导管能运送水和无机盐,筛管能运送有机物,属于输导组织.营养组织的细胞壁薄,液泡大,有储存营养物质的功能,含有叶绿体的营养组织还能进行光合作用合成有机物.因此营养组织有制造和储存营养的功能,植物的果肉、叶肉、茎中央的髓等大多属于营养组织.机械组织多由一些厚壁细胞组成,起支持作用.

   动物的组织主要有上皮组织、肌肉组织、结缔组织、神经组织4种.上皮组织主要分布在身体表面和各种官腔的内表面有保护作用,还有的分布在腺体内如唾液腺有分泌作用,如皮肤的表皮.结缔组织由大量的细胞间质和散在于其中的细胞组成.细胞间质包含基质、纤维和组织液等.结缔组织在人体分布广泛,几乎遍布所有器官.主要有支持、连接、营养的功能.其中,除了松软的起连接作用的固有结缔组织外,人体的血液组织、骨和软骨组织均属结缔组织.神经组织主要由神经细胞与神经胶质细胞组成.具有感受刺激与传导神经冲动的能力,如脑神经;肌组织由肌细胞或称肌纤维组成.按其存在部位、结构和功能不同,可分为骨骼肌、平滑肌和心肌三种,有收缩、舒张的功能.

  影响生物生活的因素有生物因素和非生物因素,生物因素是影响生物生活的其它生物,非生物因素是指阳光、空气、水、温度、土壤等.

故答案为:分生(基本)组织;保护组织;营养组织;输导组织;机械组织;疏导组织;上皮组织;肌肉组织;结缔组织;神经组织;结缔组织;阳光;空气;水;温度;土壤

I was walking along the deserted main street of a small seaside town in the north of England looking somewhere to make a phone call. My car had broken down outside the town and I wanted to get in touch with the Automobile Association .Low gray clouds were drifting across the sky and there was a cold damp wind blowing off the sea. It had rained in the night and water was dripping from the bare trees that lined the street. I was glad that I was wearing a thick coat.

There was no sign of a call box, nor was there anyone at that early hour I could ask. I had thought I might find a shop selling the Sunday papers or a milkman doing his job, but the town was completely dead.

Then suddenly I found what I was looking for. There was a small post office, and almost hidden from sight in a dark narrow street next to it was the town’s only public call box, which badly needed a coat of paint, I hurried forward but stopped in astonishment when I saw through the dirty glass that there was a man inside. He was very fat, and was wearing a cheap blue plastic raincoat and rubber boots. I could not see his face - he was bending forward over the phone with his back pressed against the glass and didn’t even raise his head at the sound of my coming nearer and nearer. Carefully and surprisedly, I remained standing a few feet away and lit a cigarette to wait my turn. It was when I threw the dead match on the ground that I noticed something bright red trickling from under the call box door.
