The “Euglena Model” (Blister Series) supplied by IBEX SCIENCES is a three-dimensional, vacuum-formed plastic relief model designed for microbiology, botany, and protozoology studies. [1, 2]
This lightweight “blister” model features a heavily magnified cross-section of a Euglena gracilis. It serves as a visual and tactile teaching aid to demonstrate how this unique, single-celled organism bridges the gap between plant and animal life. [1]
The color-coded relief structure highlights all the vital internal and external components of the cell:
1. Locomotion & Light Sensitivity
-
- Flagellum: A prominent, whip-like tail attached at the anterior end, which the Euglena rotates to propel itself through freshwater environments. [1, 2]
- Eyespot (Stigma): A bright red-colored patch near the reservoir. It functions as a shade mechanism to assist the adjacent photoreceptor in detecting light direction and intensity for photosynthesis. [1, 2]
2. Dual-Energy Production Organelles
-
- Chloroplasts: Multiple green-colored discs scattered throughout the interior cytoplasm containing chlorophyll, which allow the organism to manufacture food autotrophically in sunlight. [1, 2]
- Paramylon Granules: Distinct storage bodies containing starch-like carbohydrates produced during photosynthesis, enabling the cell to survive in dark conditions where it feeds heterotrophically. [1, 2]
- Mitochondria: The energy-generating powerhouses scattered through the fluid matrix. [1, 2]
3. Cellular Framework & Osmoregulation
-
- Pellicle: A flexible, protein-based outer layer located just underneath the plasma membrane. Because it lacks a rigid cellulose cell wall, the pellicle allows the Euglena to undergo “metaboly” (a squeezing, shifting motion to alter its body shape). [1, 2, 3, 4]
- Contractile Vacuole: A specialized circular organelle that expands and contracts to collect excess water from the cytoplasm and expel it outside, maintaining proper osmotic balance. [1, 2]
4. Genetic Control
