I have seen trees, whose leaves open at sunrise and close at sunset.

Question

of which the leaves代替 whose leaves为什么不行呢？

Answer 1

这句话是一个非限制性定语从句，只能用whose,如果要用名词所有格的话就要变句子了，去掉逗号。

Answer 2

1.
变后的句子语法虽然没有错误，但是意思侧重点不一：
1）i
saw
some
trees
whose
leaves
were
black
with
diease.
我看到了一些叶子因为疾病而变黑的树。
即saw的宾语是some
trees，而whose
leaves
were
black
with
diease为定语从句修饰trees.
2）i
saw
leaves
of
some
trees
were
black
with
disease.
=
i
saw
(that)
leaves
of
some
trees
were
black
with
disease.
我看到一些树的叶子因为疾病而变黑了。
从句leaves
of
some
trees
were
black
with
disease做主句谓语saw的宾语。
2.
in
place
of可以算作是固定的介宾短语，在句子除了做状语外，还可以做表语/后置定语/补足语。
如：he
was
in
place
of
me
in
the
company.
而和regardless
of一般只做句子的状语。

Answer 3

谁的已经有whose这个词了所以就要用
你说的介词+which一般是没有现成的词的
这样解释比较通俗吧

Answer 4

我们有时候不但要看语法是否说得通
更重要还有语言习惯！
就像说中文一样的道理，表达一个意思我们有自己特有的表达形式。

这里whose的用法通常是考点本回答被提问者采纳
