Respuesta :
Apple grows on trees can be rewritten as If a fruit is an apple, then it grows on a tree.
The conditional statement refers to the statement which speculates about things which might have happened or could happen. The word 'if' in a sentence makes it conditional. When used in the past tense it depicts the "Unreal past."
Hence, when the sentence "Apples grow on trees." when written in a conditional statement it will be written as:
If a fruit is an apple, then it grows on a tree.
