Anatomy of leaf is the detailed study of internal structure of a leaf, usually revealed by its dissection. Few big, motor or bulliform cells are present in groups here … Leaf hydraulic conductance (K leaf) varies widely among species (Brodribb et al., 2005; Sack and Holbrook, 2006; Sack and Scoffoni, 2013).Because the resistances inside and outside the leaf xylem (R ox) also vary widely and are, on average across species, of a similar order of magnitude (Sack and Holbrook, 2006), both vein traits and mesophyll anatomy have potentially strong influences on K leaf.
