Plant and organism – Central Science Supplies https://centralscience.spiderns.com School and College Science Supplies Tue, 13 Oct 2026 17:23:29 +0000 en-GB hourly 1 https://wordpress.org/?v=7.1.3 FLOWER MODEL https://centralscience.spiderns.com/product/flower-model/ https://centralscience.spiderns.com/product/flower-model/#respond Tue, 13 Oct 2026 17:23:29 +0000 http://centralscience.spiderns.com/product/flower-model/ A greatly enlarged (10x) model to demonstrate the floral components and reproductive function of the flower. Each of the eight parts of the flower model represents one of the unique structural components such as the petals, sepals, stamens and pistil. Fertilisation is shown, with pollen grains on the stigma; one pollen tube is shown penetrating the micropyle. The anthers are sectioned and the ovary is dissected to show the female gametophyte. The model also depicts the scenario for double fertilisation. Mounted on a base and supplied with key card.

PLANT CLONING II https://centralscience.spiderns.com/product/plant-cloning-ii/ https://centralscience.spiderns.com/product/plant-cloning-ii/#respond Tue, 13 Oct 2026 17:21:49 +0000 http://centralscience.spiderns.com/product/plant-cloning-ii/ Plant propagation by cloning is common in flower production. Generating a plant by cloning its tissue is an exciting and challenging experience which teaches the importance of sterile laboratory methods. Using this kit, students will establish a shoot multiplication culture using an African violet as a model, use sterile technique to develop African violet cloned cultures and induce the development of multiple shoots (clones) from the leaf tissue . Resulting plantlets may be started in soil. The complete process takes approximately three months. No hood or incubator required. Includes an instruction manual and a PowerPoint presentation with images of plant material at various stages of the experiment. Perishable reply card items ship separately upon request and only in the continental US.
Grades 9-12

PLANT CANCER https://centralscience.spiderns.com/product/plant-cancer/ https://centralscience.spiderns.com/product/plant-cancer/#respond Tue, 13 Oct 2026 17:12:00 +0000 http://centralscience.spiderns.com/product/plant-cancer/ Now cancer can be investigated in the lab, not just discussed in your classroom. Students safely study the various aspects of cancer cell growth with this totally self-contained kit. (A fresh carrot will be required.) Students explore various aspects of cancerous cell growth and learn to explain the differences between a normal cell and a cancer cell, describe similarities and differences between animal and plant cancers, identify cancer cells, identify a plant cancer or gall, and research current theories on the causes of cancer. Students grow their own sunflower plants; then induce crown gall by inoculating plant tissue with Agrobacterium tumefaciens (reply card item ships upon request and only in Continental US) which is required for inducing the cancerous growth. Students then do a Koch?s Postulates Experiment: Inducing Cancer in Carrot Tissue.
Grades 9-12

PHOTOSYNTHESIS II: THE SYNTHESIS OF STARCH https://centralscience.spiderns.com/product/photosynthesis-ii-the-synthesis-of-starch/ https://centralscience.spiderns.com/product/photosynthesis-ii-the-synthesis-of-starch/#respond Tue, 13 Oct 2026 17:06:22 +0000 http://centralscience.spiderns.com/product/photosynthesis-ii-the-synthesis-of-starch/ Photosynthesis II examines the phosphorylation of glucose to produce starch in plant cells.
Students collect phosphorylase in potato extract and use it to catalyze the synthesis of starch. They learn that starch synthesis requires primer starch to which glucose residues can be added and that inorganic phosphate inhibits starch synthesis. Required, but not included: blender, fresh potatoes. Designed for 24 students working in six groups of four.
Grades 9-14

PLANT CLONING I (INTRODUCTION TO) https://centralscience.spiderns.com/product/plant-cloning-i-introduction-to/ https://centralscience.spiderns.com/product/plant-cloning-i-introduction-to/#respond Tue, 13 Oct 2026 17:05:26 +0000 http://centralscience.spiderns.com/product/plant-cloning-i-introduction-to/ Plant propagation by cloning is becoming increasingly important in food and flower production. Generating a plant by cloning its tissue is an exciting and challenging experience which teaches the importance of sterile laboratory methods. Students will germinate carrot seeds to provide plant material from which to establish a culture, use sterile technique to grow seedlings and establish a callus culture, and induce the development of multiple shoots (plantlets) from the callus tissue. The process takes approximately four months. No hood or incubator required. Includes an instruction manual, assessment questions, and a PowerPoint presentation with images of plant material at various stages of the experiment. Perishable reply card items ship separately upon request and only in the continental US.
