BMN/B054 Animal Cell Model 20,000x: Cell Biology Teaching

BMN/B054 Guide: Teaching Organelles on a Cell Students Can Walk Around

Short answer: The BMN/B054 is an animal cell model enlarged 20,000 times. It shows the cell membrane, the cytoplasm and the nucleus, and the cytoplasm is built out with the structures that matter most in an introductory course: mitochondria, rough and smooth endoplasmic reticulum, the Golgi complex and the centrosome. The cut surface reveals the nuclear membrane, the nucleolus and chromosomes, and the model carries digital indicators for the labelled parts.

Key takeaways

• 20,000× magnification — organelles become objects rather than diagram labels
• Cell membrane, cytoplasm and nucleus shown together, so the enclosure is understood first
• Mitochondria, rough and smooth ER, Golgi complex and centrosome are all modelled
• Cut surface shows nuclear membrane, nucleolus and chromosomes
• Digital indicators mark the parts, so the model can be used for testing, not just display
• ISO and CE certified per the product page

What the model contains

Why a magnified physical cell beats a labelled diagram

In a diagram, organelles are adjacent shapes. In a hand-held model, they have volume and position — the Golgi complex sits near the nucleus, the rough ER wraps around it, the mitochondria are distributed through the cytoplasm. That spatial knowledge is exactly what students need when they later learn what each structure does.

The educational case for three-dimensional cellular models is documented. A study of cellular models used in three dimensions reported improved learning of cell structure and function compared with conventional approaches [1]. The broader pattern holds for physical models in anatomy and biology teaching [2], and controlled comparisons have found three-dimensional physical models superior to two-dimensional computer presentations for this kind of learning [3].

There is also a practical argument. A biology lab that cannot afford electron micrographs of its own still needs students to know the difference between rough and smooth ER, and a durable classroom model delivers that knowledge every year.

Running a lesson with the B054

• Control the magnification story first. Ask students what "20,000 times" means: a 10 µm cell becomes something you can hold.
• Name structures with the model in hand. Have one student point while another names, then swap roles.
• Build function onto form. For each organelle, ask one question about its function — why is the rough ER studded, what does the Golgi do to a protein, why does the nucleus need a membrane.
• Use the cut surface. The nuclear membrane, nucleolus and chromosomes are only visible at the cut; make students find that plane.
• Run a numbered-identification quiz. The digital indicators allow a fast, objective quiz with no preparation.

What to check before you order

• Language of the indicators. Ask whether the digital indicators are in English or bilingual.
• Size and handling. The page does not publish physical dimensions; request them so you know whether the model suits a bench demonstration or a small group.
• Stand. Confirm whether a base or stand is included in the packing list.
• Price and certification documents. The page quotes on request; ask for the current price list and copies of the ISO and CE documentation for your procurement file.

FAQ

Q1. What is the BMN/B054?
It is a model of an animal cell enlarged 20,000 times, showing the cell membrane, cytoplasm and nucleus together with the main organelles.

Q2. Which organelles are modelled?
Mitochondria, rough and smooth endoplasmic reticulum, the Golgi complex and the centrosome, plus the nuclear membrane, nucleolus and chromosomes at the cut surface.

Q3. Why is the magnification 20,000×?
At that scale the organelles become large enough to inspect and to label physically, which is the point of the model.

Q4. Can it be used for assessment?
Yes. The digital indicators allow structures to be identified by number, which works well for a quick oral or written quiz.

Q5. Is the model certified?
The product page states ISO and CE certification.

Q6. How do I get the best price?
Email ada-manikin@adaanatomy.com with the model (BMN/B054), the quantity you are considering and your destination port; the page quotes on request and our export team will reply with pricing, lead time and configuration.
