BoS 16 PLANT CELL

Enlarged 3000 times, in SOMSO-Plast. After Prof. Dr. W. Jung. Showing the microscopic structure. In one piece. On a base, with explanatory note. Height: 7 cm., width: 32 cm., depth: 19 cm., weight: 700 g.

Please call for prices.

BoS 16/1 PLANT CELL

After Prof. Dr. W. Weber. Enlarged approximately 6000 times, made in transparent special plastic material. The model provides a slightly schematic picture of a mature cell from the assimilation tissue of a plant. It combines both light and electron microscopic aspects and shows the cell components for the most part with their electron optical fine structure. Apart from the layering of the cell wall it shows the configuration of the cytoplasm and the essential cell organs, such as the nucleus, chloroplasts, mitochondria, endoplasmatic reticulum, dictyosomes and ribosomes. The use of transparent material gives an insight into the structures behind the section thus eliminating the need for dismantling the model. The stand is made up of the neighbouring cells at the bottom. On a base with explanatory key. In one piece. Height: 36 cm., width: 31 cm., depth: 27 cm., weight: 1.7 kg.

Please call for prices.

BoS 16/2 CHLOROPLAST OF HIGHER PLANT

After Prof. Dr. W. Weber. Enlarged approximately 60,000 times, in SOMSO-Plast. The model shows the submicroscopic fine structure of a chloroplast on three vertical plane cross-sections with the outer and inner chloroplast membrane, grain and stroma thylacoids, plastid stroma, starch inclusions and osmiophile globules. The grain thylacoid masses lie in front of the cross section planes and can be taken out together with the linking stroma thylacoids. Through the three cross-sectional planes and the superimposed and removable parts, the model gives a depth of dimension as achieved when viewing cross-sections through electron microscopes. Separates into 2 parts. On stand with base and explanatory key. Height: 38 cm., width: 39 cm., depth: 26 cm., weight: 3.2 kg.

Please call for prices.

BoS 17 DECIDUOUS LEAF

Enlarged 700 times, in SOMSO-Plast. After Prof. Dr. W. Weber. Transverse and longitudinal sections showing the microscopic formation. In one piece. On a base plate, with explanatory key. Height: 41 cm., width: 29 cm., depth: 12 cm., weight: 2.8 kg.

Please call for prices.

BoS 17/1 SECTION THROUGH THE LEAF OF THE HELLEBORUS

Enlarged 700 times, in SOMSO-Plast. After Prof. Dr. W. Weber. The model shows the upper epidermis with cuticula, the assimilation network (separated into pallisade and parenchymatous cells with cytoplasmic lining) and the lower epidermis with stomates. In one piece, on a stand with base and explanatory key. Height: 40 cm., width: 39 cm., depth: 26 cm., weight: 3.4 kg.

Please call for prices.

BoS 17/2 STOMATE OF THE UNDERSIDE OF A CHRISTMAS ROSE LEAF

Helleborus niger, many times enlarged, in SOMSO-Plast. After Dr. Gerlach, Botanical Institute Erlangen. Shown are guard cells, accessory cells, stomate respiratory cavity. One half of the model shows the stomate, the other the function can be demonstrated symbolically. Separates into 2 parts. Height: 23 cm., width: 45 cm., depth: 37 cm., weight: 6.6 kg.

Please call for prices.

BoS 18 MODEL OF A CROSS-SECTION OF A WHEAT GRAIN AS AN EXAMPLE OF A CARYOPSIS

Triticum aestivum L., enlarged approx. 75 times, in SOMSO-Plast. After Prof. Dr. W. Jung. The model demonstrates a wheat-grain divided in half lengthways. The embryo can be removed. The cell layers of the fused fruit and seed shell are represented in cross-section, longitudinal and surface section. The remainer of the pistil pulvinus with the "awns" is located at the tip, opposite the basal germinal layer. Separates into 2 parts, on a stand with base and explanatory key. Height: 43 cm., width: 52 cm., depth: 26 cm., weight: 4.2 kg.

Please call for prices.

BoS 19 FERTILISATION OF THE ANGIOSPERM

Polygonum-type, enlarged 300 times, in SOMSO-Plast. After Prof. Dr. W. Jung. Longitudinal section showing nodes with germinating pollen spores and embryo sac, stamen with pollen in sagittal section. Showing in detail the microscopic structure. On a base with explanatory key. In one piece. Height: 66 cm., width: 30 cm., depth: 14 cm., weight: 3.3 kg.

Please call for prices.

BoS 21 ANATOMICAL STRUCTURE OF PINE WOOD

Pinus silvestris, enlarged approx. 350 times, in SOMSO-Plast. After Prof. Dr. W. Jung. The model shows the anatomical structure of pine-wood in various sections: transverse, radial longitudinal and tangential longitudinal through the cambium zone, original wood, secondary wood and bark. Showing all the elements of the wood structure. In one piece, on base with explanatory key. Height: 15 cm., width: 65 cm., depth: 30 cm., weight: 5.2 kg.
