Tracheophyta / Magnoliopsida: Phaseolus hypocotyl c.s.
[3863354]
$25.00

Prepared microscope slide: Tracheophyta Phaseolus hypocotyl cs

Kingdom: Plantae / Subkingdom: Viridiplantae / Infrakingdom: Streptophyta / Superdivision: Embryophyta / Division: Tracheophyta / Subdivision: Spermatophytina / Class: Magnoliopsida / Superorder: Rosanae / Order: Fabales / Family: Fabaceae / Genus: Phaseolus L.

Synonyms: bean, wild bean.

The hypocotyl is the part of a plant embryo or seedling that lies between the radicle and the cotyledons. Upon germination, the hypocotyl pushes the cotyledons above the ground to develop. It eventually becomes part of the plant stem. Most seed-bearing plants have hypocotyls, but the grasses have different, specialized structures.

The main image of hypocotyl of Phaseolus c. s. is at 40x. Five additional views of the hypocotyl are presented, one at 100x and four at 400x shown from the outer edge in sequence toward the center. The images were illuminated using the Pedersen Dual Quarter Wave Technique (PDQWT)*

*The Pedersen Dual Quarter Wave Technique (PDQWT) involves placing over the source of illumination a pair of one quarter wave polarizing surfaces that are rotated, one against the other, to control the amount of back light on a prepared microscope slide.

This slide was prepared by Triarch, Inc. in Ripon, MI 54971 # 11-354-7. This appears to be a very early version of the slide. The “11” and the “7” are written on the label as well as the notation that it is the hypocotyl cs. There are two samples on the slide. It has been used in an unknown classroom setting. From the quality of the work, and the general appearance, it is estimated to have been prepared prior to 1970.
