Dicotyledon plant stem, light micrograph

Dicotyledon plant stem. Light micrograph of a longitudinal radial section through a typical dicotyledon stem. The section has passed through a vascular bundle and other stem tissue (some of which have ring thickening, red). The tissue layers at right are mostly xylem and parenchyma. There is also a layer of cambium (light blue, centre). Several rows of phloem sieve tubes (yellow-green) are at centre left. At left are large parenchyma cells (blue) of the inner cortex of the stem.

Antelope Canyon an excellent example of a slot canyon, formed by erosion of Navajo Sandstone primarily due to flash flooding. Rainwater, especially during monsoon season, runs into the extensive basin above the slot canyon sections, picking up speed and sand as it rushes into the narrow passageways forming the characteristic sinuous shapes in the rock.Lower Antelope Canyon, Page, Arizona, USA
