Introducing a concise set of 6 models, offering a simplified and compact representation of chromosome changes. These models provide an accessible overview, covering key phases from the resting nucleus to the formation of daughter cells.

Intricate structure of plant tissue with this model, showcasing cambium between xylem and phloem. A single strip of phloem with a single cambium is depicted, featuring both open and closed bundles. Enlarged approximately 550 times, this detailed model is presented in one piece on a base, accompanied by a key card for reference.

It represents the structures involved in the flowering plant’s life cycle, aiding students in visualizing and understanding the process. Clear labelling of life cycle steps and cells enhances comprehension. Perfect for biology classrooms, this model features key structures including flower, stamen, carpel, ovary, pollen tube, ovule, embryo, seed, seedling, and sporophyte.

Internal anatomy of a young dicotyledonous root with this model, showcasing key features such as the taproot system, epidermal cells resembling root hairs, multi-layered cortex, and loose parenchyma cells with intercellular spaces. Mounted on a board for easy display and accompanied by a key card for reference.

This model showcases the different tissues and vascular bundles of maize, including scattered, closed, and collateral types, in both transverse and longitudinal sections. It allows for detailed examination of internal structures such as large pitted vessels and spiral and annular vessels, revealing cell wall thickenings in longitudinal sections. Highlights parts like the cortex, endodermis, and pericycle. Mounted on a base and accompanied by a key card for reference.

The model offers dual internal views, aiding comprehension of dicot stem structure and function. Mounted on a board for display, accompanied by a key card for easy reference.
