BIX-C0002 Paramecium Model: A Two-Piece Cutaway of a Single-Celled Organism

Short answer: BIX-C0002 is a greatly enlarged Paramecium model built in two pieces. Opening it exposes a longitudinal section, and that section is the point of the model: it shows the inner organelles — food and contractile vacuoles, lysosome, macro- and micronucleus — as separate physical objects. Students who have only seen a Paramecium in a textbook diagram see one outline; here they see the internal machinery of a cell that performs every function of life at once.

Key takeaways

• Two pieces, one section. The model splits to reveal a longitudinal section, so the interior can be examined directly.
• Named organelles. The published description identifies food and contractile vacuoles, lysosome, and macro- and micronucleus.
• Greatly enlarged. The magnification is what makes a single cell teachable to a full class.
• Detail is the design goal. The manufacturer states that all structures are reproduced in great detail.
• Quote by quantity. Price is given as "inquiry for best offer" and is stated to depend on order quantity.

What the longitudinal section shows

Why a protozoan needs a physical model more than most topics

The Paramecium is the standard first example of "a cell that is an organism" — and it is also one of the hardest to teach, because the scale is invisible and the parts are all inside one another. Lab work depends on microscopy, where the field of view is small, the specimen moves, and each student sees a different frame. A classroom-sized model converts that private, momentary image into a shared object.

The education evidence supports the same conclusion. A meta-analysis of comparative studies of physical models in anatomy teaching found a measurable advantage for the physical model over the alternatives it was tested against [1]. A separate comparison of imaging anatomy teaching reached a comparable verdict: students who worked with a physical model outperformed those who used 3D computer models and textbooks [2].

For BIX-C0002 the practical consequence is simple: the model should be opened on the bench and passed around during the lesson, not shown from the front of the room.

Classroom sequence

1. Start closed. Show the exterior first and ask students to describe the shape and the axis of the cell before anything is revealed.
2. Open the model. Split the two halves and let the class see the longitudinal section as one continuous interior.
3. Name the named structures. Point out food vacuoles, contractile vacuoles, the lysosome and the two nuclei in that order — this follows the published description of the model.
4. Set a problem. Ask why a single cell needs a contractile vacuole at all, and what would happen in fresh water without one.
5. Close it again. Return to the exterior and ask students to indicate where the internal structures sit — a fast check on whether the section was actually learned.
6. Compare within the series. Place the Paramecium next to other cell models in the catalogue and ask which structures are shared across cell types.

Before you order

• Quantity for the quotation. Price is explicitly subject to order quantity, so state the number of units in your first enquiry.
• Mounting and storage. Confirm whether the two halves include a stand, and how the model should be stored between terms.
• Course alignment. Ask which other Biology Series models — plant cell, protozoa or cell-division models — ship on the same lead time, so one order covers the unit.

FAQ

Q1. What is BIX-C0002?
It is a greatly enlarged Paramecium model supplied in two pieces; separating them reveals a longitudinal section of the cell.

Q2. Which internal structures are shown?
The published description names food vacuoles, contractile vacuoles, lysosome, and the macro- and micronucleus.

Q3. Is the model enlarged?
Yes. The description states that the model is greatly enlarged, and that all structures are reproduced in great detail.

Q4. Can it be used for both microscopy and macroscopic teaching?
It is designed for macroscopic teaching: it gives a class a shared, physical view of structures that are otherwise only visible through a microscope.

Q5. Is the price fixed?
No. The product page lists the price as an inquiry for best offer and states that it is subject to the quantity of the order.

Q6. How do I get a quotation?
Email adaanatomy@adaanatomy.com with the model (BIX-C0002), the quantity and your destination port, and the sales team will return the offer.

Request a quotation

Write to adaanatomy@adaanatomy.com for a quotation on BIX-C0002 — include the number of units, since the published price depends on order quantity. If your biology unit also covers plant cells or cell division, ask for those models in the same enquiry; they can be consolidated into one order and one shipment.
