This is a high quality slide made especially for us here at Nature's Workshop Plus! This slide of Grantia spicules is used with the Exploring Creation with Biology course by Dr. Jay Wile. Each slide is individually made, and will vary slightly from the one pictured here. The Grantia spicules pictured here is magnified at 400x. Our model #131 microscope was used to photograph this slide specimen. The black pointer near the top of this picture is a feature of this microscope, and is not a part of the slide.
