I It rained most of today so I compared these two oak leaves working inside. One new thing I learned is  that not only each lobe had a vessel, but each sub-lobe had one as well.  I wondered if the branched "veins" only carried sugars away from the leaf or if nutrients also flow back into the leaf.  It seems there are these types of oak species (rounded or pointed lobes), and oaks with no lobes.  The leaves reminded me of my own hand, especially the back. I felt that I need to draw hundreds of leaves before I'll begin to appreciate the structure of leaves, and that's just the leaf!  The whole tree.  It's an endless journey. The other student drawings are so interesting!
