22、I(6分)粗齿冷水花生长于向阳处叶为肉质，生长于阴蔽处叶为革质。为了验证“粗齿冷水花的革质叶是受环境因素的影响而是形成的”，生物兴趣小组的同学进行了如下两组试验，请分别指出实验思路能否达到实验目的，为什么？
(1)实验一：①于野外取叶肉质的一株粗齿冷水花上的种子若干，分成AB两组，分别栽种在装有沃土的花盆中，给予适宜的外界条件，催芽；
②发芽后，在适宜的条件下培养，其中A组放在向阳处，B组放在阴蔽处；
③一段时间后观察粗齿冷水花的叶质。
答： ，
(2)实验二：①于野外取一株叶肉质的粗齿冷水花，在同一直根上切取相似的若干段，分成AB两组，分别埋在装有沃土的花盆中催芽；
②再将A组放在向阳处，B组放在阴蔽处继续培养；
③一段时间后观察粗齿冷水花成熟叶质的变化。
