The xylem and phloem that make up the vascular tissue of the stem are arranged in distinct strands called vascular bundles, which run up and down the length of the stem
Photomicrograph of hemp fibers, Cannabis sativa. Hemp produces bast fibers which grow in bundles which are broken apart to produce fiber. Cell walls are visible in some of the fibers. Wet mount, 10X objective, transmitted brightfield illumination. Note - very shallow depth of field, chromatic aberration and uneven focus are inherent in light microscopy.
Host cells with spores (mold) are inside wood under the microscope for education.

After dopamine binding, the dopamine receptor changes his shape and binds the inactive G protein.The G protein expels its GDP molecule replacing it by GTP. and falls into two pieces. The Galpha subunit binds to and activates the enzyme adenylyl cyclase, which produces then cyclic AMP spreading a signal through the cell.
