You found the following plants growing on campus during a field trip: a small plant with a notable absence of root hairs; a short, stubby plant with an enlarged taproot; a tall annual herb with fungal strands extending from its roots; a low-growing plant with nodules on the roots; and a woody shrub with an extensive fibrous root system. Based on this scenario, which plant is most likely a legume with nitrogen-fixing bacteria?

Question
