- While surveying plants in the jungles of Borneo, you come across a flowering plant that you have never seen before. You examine a flower closely and you see that it is radially symmetric, has organs arranged in a spiral phyllotaxy and it has many stamens. Based on your knowledge of flowering plant lineages you conclude that a. the plant must be a basal angiosperm b. the plant must be a Magnoliid c. the plant could be a monocot or a eudicot d. the plant could be a basal angiosperm or a Magnoliid e. the plant must be a monocot part ii Which one of the following is NOT supported by our current view of animal taxonomy and evolution based on molecular phylogenetics a. That earthworms and more closely related to squid than to nematode worms. b.

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_forward
