a needle
a seed

Explanation:

To determine which part of a pine tree can grow into a new tree, we analyze the life cycle diagram. A needle is a leaf - like structure for photosynthesis and does not develop into a new tree. A seed contains the embryo of a new plant. In the pine tree life cycle, seeds are dispersed and can germinate to form a seedling, which then grows into an adult tree. So, a seed is the part that can grow into a new pine tree.

a seed
