(一)教材分析原生动物门是动物界中最原始、最低等的一个门,在动物学中居于首屈一指的起始位置,这正是它在动物界中的重要地位。本章以常见的草履虫为代表,从生活环境,形态结构和生理特点加以叙述,进而概括出原生动物门的一般特征。草履虫是一个细胞的动物体,身体微小,结构简单,这是本门动物的特殊性。虽然草履虫是一个细胞,但它和其他高等动物一样,有其运动、呼吸、消化、排泄、生殖和应激性等生命的基本特征。这又是本门动物的复杂性。草履虫的特殊性和复杂性就恰好构成本章教材的重点内容。
(A) textbook analysis Protozoan door is the most primitive animal, the lowest door, in zoology in the premier starting position, which is its important position in the animal kingdom. This chapter takes the common Paramecium as the representative, narrates from the living environment, the morphological structure and the physiological characteristics, and then generalizes the general characteristics of the protozoan door. Paramecium is a cellular animal body, body is small, simple structure, which is the particularity of the animal. Although Paramecium is a cell, like other higher animals, it has the basic characteristics of life, movement, respiration, digestion, excretion, reproduction and stress. This in turn is the complexity of this animal. Paramecium peculiarities and complexities just constitute the focus of this chapter teaching materials.
