SEO Page Rank & Linking Question?

Lets say I have website that is listed as www.fruits.com
which i am acquiring links for. Would the pages within the domain such as www.fruits.com/apple and www.fruits.com/orange share the same PR rank or do i have to perform all of the same linking strategies as performed with the initial page (domain name: www.fruits.com)

Any recommendations for these questions would be useful.

PR is calculated for each page individully. So fruits.com could have a PR of 3, and fruits.com/apple can have a PR of 4, while fruits.com/pear will have only a PR of 1.
A good internal linking scheme however will level the PR of your pages more or less.
