Beauty in a leaf

In microscopy, science plants on September 12, 2010 at 7:35 pm

Xylem showing spiral rings of tracheids as shown in real life photograph below.

Fluorescent microscopy shines a single wavelength of light onto an specimen, then captures the glow that is produced. Here nuclei are bright blue, a nuclear protein is bright green and the curly cues are the auto-florescent cell walls of xylem tissue. In the diagram above you can see a cartoon of the tracheid, that is the water carrying pipe in plants. Click the image below to see a larger view of the spiral shaped cell wall thickenings. © 2011 Sharon Settlage.  All rights reserved.
