Which word is best used when describing both a tiny moss and a huge oak tree?

Question

unicellular
multicellular
vascular
nonvascular

Answer 1

The best word to use when describing both a tiny moss and a huge oak tree is multicellular. Both mosses and oak trees are made up of multiple cells, as opposed to unicellular organisms which consist of only one cell. Additionally, discussions of vascular and nonvascular plants would not apply to both, as mosses are nonvascular while oak trees are vascular.
