六年级科学第五单元知识点总结
第二十课：蚯蚓找家 主要知识点： 在不同的环境中生活着不同的动物，动物与环境相互依存。北 极熊生活在寒冷的北极，鲸鱼生活在大海中，骆驼生活在沙漠中，大象生活在热带雨林。 蚯蚓喜欢生活在阴暗潮湿的环境里，防止水分的丧失是蚯蚓生 存的关键。喜欢的食物主要是：腐烂的落叶、枯草、蔬菜碎屑等 生长于沙漠中的仙人掌，叶子是针形，以减少水分蒸发。 蚯蚓的生活习性：六喜：喜阴暗、喜潮湿、喜安静、喜温暖， 喜甜，酸味、喜同代同居；六怕：怕光、怕震动、怕水浸泡、怕闷气、怕农药、怕酸碱。 第二十一课：变色龙 主要知识点： 1、动物的自我保护是根据环境的变化而变化的。 2、动物适应栖息环境而具有的与周围环境色彩相似的体色叫做保 护色。生物的体色与周围的环境越相似，就越容易隐蔽自己。例如：变色龙以改变自己身体的颜色来适应不同的环境。 3、某些有恶臭或毒刺的动物所具有的鲜艳色彩和斑纹叫做警戒色。例如毒箭蛙用鲜艳的颜色来警告捕食者不要吃它。 4、动物依靠体态、颜色模拟不可食的物体或有警戒色的不可食的 动物，借以保护自己，这种现象叫做拟态。例如：枯叶蝶借助与枯叶相似的外表保护自己免遭其他捕食者的侵袭，这是一种生物对另5、一种生物形态的模仿。假死是动物躲避天敌的捕食时，外表看 起来好像已经死亡，实际上还活着的一种状态。 6、动物保护自己、适应环境的方式有哪些？举例说明。 答：保护色：变色龙改变身体的颜色； 警戒色：如毒箭蛙、黄蜂； 拟态：如竹节虫、尺蠖、枯叶蝶； 冬眠：如青蛙，蛇； 断尾：如壁虎断尾逃生； 解放军战士为什么要穿迷彩服？它是根据什么设计的？ 答：迷彩服与周围的环境相似，可以伪装自己，不被敌人发现；这是根据动物的保护色的原理设计的。 第二十二课：植物向哪里生长 知识点总结： 各种植物必须生活在一定的环境中，植物的生活环境包括阳光、 温度、水、空气、土壤等。 2、向日葵的“头”会随着太阳位置的变化而转动，这种受光刺激 而引起的生长弯曲现象叫做向光性。例如：一般说来，北半球树木的南侧比北侧长得好。 植物的根向地下生长的现象称为向地性，也是地心引力作用的 结果。
