| QCAA Biology General senior syllabus landing and 2025 v1.3 PDF | Current applicable version and Unit 1 printed pp.20–22: Topic 1 title/hours and bullet order, nine organelle names, hierarchy, inquiry boundaries, plus Units 1–2 school assessment p.6. Verified against the live official PDF web rendering; syllabus remains QCAA copyrighted. We link/locate points and independently write the lesson language; we do not reproduce pages, diagrams, achievement standards or a QCAA assessment. Recheck version before school adoption. |
| NIH MedlinePlus Genetics, What is a cell? | Government explanatory cross-check for membrane, nucleus, cytoplasm, mitochondria, ER, Golgi, lysosomes, ribosomes. We used facts, no images/text reuse. |
| NHGRI Cell glossary, Ribosome, Rough ER, Golgi, Mitochondria, Vacuole, Organ | Government fact cross-check for cell structures, pathway simplification, central vacuole, hierarchy. No figures or copied wording used. |
| NIH-indexed review of plastid development | The review links chloroplast development with photosynthetic machinery and explains that normally underground root cells develop other plastid forms while unusual light exposure can induce chloroplast development. This supports the deliberately bounded “not every plant cell” wording. Facts only; no diagram or passage reused. |
| NCBI MeSH erythrocyte record and 2022 PubMed paper on erythrocyte translation | Checked the important mature mammalian red-cell nucleus exception. Research on residual ribosomes/translation means we deliberately do not claim mature red cells universally lack ribosomes. This exception prevents overgeneralising the comparison card. |
Model integrity: Pond bacterium, leaf and intestinal schematic inventories, J/K/L/M, every caption, task, printable diagram and answer are newly authored fictional teaching models. They are not photos, clinical records, live culture results or claims that an organelle list is exhaustive. Cells, health-adjacent tissue examples, wetlands, fermentation, display design, water balance and transport contexts are conceptual, not diagnosis, lab protocol or First Nations knowledge. No external image, audio, worksheet, cultural story, translation or generative third-party source is included. We did not use a textbook's exercises or visuals. The external URLs serve fact/source verification and are not required to complete the tasks.
