The “Amoeba Proteus Model” (Blister Series) by IBEX SCIENCES is a three-dimensional, vacuum-formed plastic relief model designed for microbiology, zoology, and introductory biology courses. [1, 2, 3]
This lightweight “blister” format features a highly magnified, color-coded cross-section of an Amoeba proteus. It serves as an essential visual and tactile learning tool, helping students conceptualize how a single-celled eukaryotic organism without a fixed shape undergoes locomotion, captures food, and manages cellular waste. [1, 2, 3, 4]
The model provides clear, raised anatomical detailing of the following internal and external structures: [1, 2, 3]
1. Cellular Boundary & Locomotion
-
- Plasmalemma (Cell Membrane): The thin, flexible outer membrane that encloses the cytoplasm, allowing the cell to continuously shift its shape. [1, 2]
- Pseudopodia: The “false feet” or blunt, finger-like projections of cytoplasm. The model illustrates how these extensions are thrust forward for amoeboid movement and to engulf food particles. [1, 2, 3]
2. Internal Cytoplasm Layering
3. Feeding & Digestive Framework
-
- Food Vacuoles: Circular compartments scattered throughout the endoplasm. They show the different stages of intracellular digestion after food (such as bacteria or small algae) is engulfed via phagocytosis. [1, 2, 3, 4]
- Phagocytic Cups: The model often showcases the dynamic bending of pseudopodia forming around a food particle right before it is sealed into a new vacuole. [1, 2]
4. Osmoregulation & Cellular Waste
5. Control Center
