- You are asked to survey an area and identify all plant and animal species you come across. On your survey, you come across a plant you are not familiar with and must do some research to figure out what it is. To do this, your first step is to determine whether this plant is classified in the class Monocotyledonae or a Eudicotyledonae. Explain how you can tell if this plant is a Monocot or Eudicot by describing the differences in their flowers, seeds, roots, stems, and leaves. 1.arrow_forwardOne characteristic that separates ferns from complex vascular plants is that ferns do not havea. a vascular system.b. chloroplasts.c. alternation of generations in their life cycle.d. seeds.arrow_forwardWhy must bryophytes inhabit damp environment?
