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。

答:
