1改进原因初中植物学课本在做验证种子成分，小麦胚中含有脂肪的实验时，要求做法是将烘烤后的小麦的胚切下，放在白纸上挤压，然后观察纸上留下的透明亮点，以证明白纸被油（脂肪）浸透，进而证明小麦胚中含有脂肪的结论。然而学生按上述方法做实验时，成功率极少，分析其原因 1 Improvement Reasons In the experiment for the junior high school botany textbooks to verify the seed composition and wheat embryos contain fat, the practice is to cut the embryos of the baked wheat and put it on a white paper, and then observe the paper to leave The transparent highlights to prove that the white paper is saturated with oil (fat), thus concluding that the wheat germ contains fat. However, when students do experiments according to the above methods, the success rate is very small, and the reason is analyzed.
