PLNT_S 2125 Lecture Notes - Lecture 5: Palisade Cell, Guard Cell, Boundary Layer
Document Summary
Intake of co2 i: liberation of o2, produce sugars b, water vapor, co2, and o2 move from high concentration to low concentration. In grasses, they usually follow in a line: this is different in dicots, structure, upper is dicot, lower is monocot, radially arranged micro fibrils give the dicot guard cells power when enlarged, guard cells a. Immediately surround the pore: stomatal pore, subsidiary cells, 2-4 cells flanking the guard cells, assist in function, not always preset in dicots, provide solutes to the guard cells that allow for infiltration of water. 1: see caption, boundary layer, layer of air that surrounds the leaf whose gas concentration, temperature, and pattern of air flow are modified by the leaf. 2: dotted line represents boundary layer, the more the wind is blowing, the smaller the boundary layer gets. If wind is constant, the boundary layer increases with leaf size.
