Each pollen structure has over a hundred sperm cells, and each pinecone has several egg cells inside it. Not all of them will get fertilized, but in a successful instance, wind or gravity will cause a tiny piece of the pollen, one sperm cell, to fall inside of the female pinecone to fertilize it.

Let's represent the number of acorns Lin has as A. Since Lin has 7 fewer pinecones than acorns, we can express the number of pinecones she has as A-7. Given that Lin has 4 pinecones in total, we can set up the equation A-7 + 4 = A. Solving this equation, we find that Lin has 11 acorns.

No; pinecones are the seepods of coniferous (evergreen) trees.
