Which word means sapling?

The word that means sapling is "fuosseed." A sapling is defined as a young tree, typically one that is still growing and hasn't yet reached maturity. This term is often used in forestry, gardening, and environmental science contexts to describe young trees that are establishing themselves in a given area.

The other options do not denote a specific meaning associated with young trees or saplings. They may represent unrelated concepts or terms that do not have a recognized definition in the context of botany or horticulture. This makes "fuosseed" the correct choice for identifying a sapling.
