问题 实验题

(5分,每小题1分)(1)图是成熟植物叶肉细胞结构示意图。(2)图、(3)图分别为显微镜观察的人体口腔上皮细胞、洋葱鳞片叶表皮细胞。请根据图回答问题:

1(3)图中的细胞与(2)图中的细胞结构上的区别是_______。

A. (3)图中的细胞有细胞壁,(2)图中的细胞没有

B. (3)图中的细胞有液泡,(2)图中的细胞没有

C. (3)图中的细胞有细胞壁,液泡,(2)图中的细胞没有

D. (3)图中的细胞有细胞壁、液泡、叶绿体,(2)图中的细胞没有

2(1)图、(2)图、(3)图中的细胞都有,且与能量转换有关的结构是_______。

A. ③    B. ④    C. ⑤    D. ⑥

3(3)图所示结构在结构层次上属于_______。

A. 细胞    B. 组织    C. 器官    D. 系统

4 临时装片的制作主要在净片、滴液、取材、盖片、染色五步,(2)图中出现气泡,关于气泡说法不正确的是

A. 气泡边缘黑、中间亮    B. 产生的气泡可用引流法去除

C. 气泡可能有细胞结构    D. 气泡的产生是盖片操作错误产生的

5上图中细胞在体内生长到一定时候可以再分裂的是_______。

A. (1)图    B. (2)图    C. (3)图    D. 都不可以

答案

1C  2 D 3 B 4 C 5D

题目分析:1、图2是人的口腔上皮细胞,图3是洋葱鳞片叶表皮细胞,人的口腔上皮细胞的结构有:细胞膜、细胞核和细胞质,洋葱鳞片叶表皮细胞的结构有:细胞壁、细胞膜、细胞核、细胞质和液泡,所以答案选C。

2、细胞中的能量转换器有叶绿体和线粒体,叶绿体是植物细胞的特有结构,线粒体动植物细胞都有,所以此题答案为D。

3、许多形态相似、结构和功能相同的细胞构成组织,所以图(3)是组织。

4、气泡是由于盖盖玻片的方法不当造成的,气泡的内部一片空白、无结构、多为圆形、气泡的边缘较黑、较宽、用镊子轻压盖玻片,气泡会变形移动。

5、图中的这些细胞都已经失去分裂能力,它们会发生分化,形成各种组织。

点评:此题是基础知识题,难度一般,能够熟练掌握动植物细胞的结构和功能,即可解题。
