Stucture of a ChloroplastAs I mentioned before on my Habitat page, Robinia pseudacacia is an autotroph, meaning that it makes its own food.  It accomplished this through photosynthesis, which is made possible through structures known as  chloroplasts which are located in the leaves.  The diagram to the right gives you an idea of what this structure looks like.  Thanks to chloroplasts, the black locust is able to take the sun’s energy and convert it into sugars like glucose and sucrose.               

Blossoms on Black LocustWater uptake in Robinia pseudoacacia occurs through the roots.  Remember the xylem and phloem structures I talked about on my adaptations page? If you looked at this page already, you know that the xylem and phloem are responsible for the movement of water and sugars up and down this tree. More specifically, the xylem is responsible for water transport and the phloem is in charge of the movement of sugars.
