  1. The white baneberry (actaea pachypoda) is a eukaryote in the plantae kingdom. It is found down the ranunculaceae branch and is most closely related to baneberry, snakeberry, black bugbane and other members of the actaea genus.
  2. All the observed organisms have adapted some form of leaves as a method to absorb sunlight as a necessary component of their metabolic processes. The interesting divergency arises out of the different shapes and placements of the leaves to maximize the surface area in contact with the sun. For example the Joe-Pye weed has its leaves placed around the stem extending in all directions and curving upwards to compete with other plants near it's height. The common Duckweed on the other hand has much smaller leaves at its tip, giving it the buoyancy to float in the water and absorb the sunlight by covering the entire body of water. These differences can highlight the difference paths evolution has taken to adapt to their ecological niches.
  3. The Common Duckweed is unique among these organisms to have evolved in a manner that it is fully aquatic. A notable difference caused by these adaptations is that it absorb its nutrients not through soil but through what flows through the water it rests upon.
