Product Details

With the gymnospermae microscope slide set, study 15 examples of seed-bearing vascular plants—cycads, the ginkgo, yews and conifers. Meaning “naked seeds,” gymnosperms’ seeds are not enclosed in an ovary but rather develop on the surfaces of scale- or leaf-like appendages or the ends of stalks. Slide set includes a full-color brochure with corresponding pictures.
