This route · Guided Media & Evidence
A media- and dataset-supported route with supplied learner sheets, kaiako answers and a formative portfolio. SA:V, division rates and whole-cell evidence receive dedicated lessons.
The engine room of life
Cells stay alive because transport, enzyme activity, energy transformations, DNA replication and division form one connected system. Across ten 60-minute lessons, ākonga move from structure–function reasoning to evidence-rich explanations that connect several biological ideas in context.

These are parallel Year 12 routes for the same external standard—not one course followed by the other. Choose one as your teaching spine, or remix by concept using the paired lesson links.
Parallel route · Mechanism & Exam Synthesis
A fine-grained route that separates transport and enzyme mechanisms across paired lessons, builds ten formative exercise-book sections, and culminates in integrated exam-style explanation.
Either route supports later Level 3 work in homeostasis, genetic transfer and socio-scientific inquiry.

Science · Living World · Level 7 · Life processes:
“Explore the diverse ways in which animals and plants carry out the life processes.”
This unit develops that objective through plant and animal cell specialisation, membrane transport, photosynthesis, respiration, enzyme action, DNA replication and mitosis. Read the full curriculum and Level 2 Biology alignment.
Learning intentions and success evidence
Know
Locate and describe relevant structures and processes, including facilitated diffusion, both process groups in photosynthesis, aerobic and anaerobic respiration, enzyme factors, semi-conservative DNA replication and mitosis.
Explain
Use biological mechanisms to explain how structure, resource availability and environmental conditions affect cellular activity.
Connect
Build sustained explanations that link several ideas to supplied evidence and to the functioning of a cell or organism.
Ready-to-use unit resources
Learner Evidence Pack
All ten learner sheets: datasets, cell profiles, sorting cards, practice responses and the final synthesis context.
Portfolio Workbook
A ten-part printable record with evidence prompts, writing space and explicit checkpoints.
Kaiako Guide
Preparation, indicative answers, formative moderation, source boundaries and media record.
Lesson sequence
1 · Cell structure and function
Infer specialised cell roles from organelle evidence and distinguish observation from named knowledge sources.
2 · Membrane transport
Decide among diffusion, facilitated diffusion, osmosis and active transport in cell contexts.
3 · Surface-area-to-volume ratio
Calculate, graph and explain how cell size constrains exchange.
4 · Photosynthesis
Connect thylakoid and stroma processes and explain limiting-factor patterns.
5 · Cellular respiration
Compare aerobic and anaerobic pathways and connect ATP supply to cell function.
6 · Enzyme action
Explain rate patterns involving temperature, pH, substrate, cofactors, coenzymes and inhibitors.
7 · DNA replication and mitosis
Sequence the cell cycle and connect semi-conservative replication to daughter-cell continuity.
8 · Division rates
Use simulated tissue evidence to explain direct and indirect resource effects on cell division.
9 · Extended answers
Moderate teacher-authored responses and upgrade disconnected facts into causal explanations.
10 · Cell-biology synthesis
Integrate temperature, transport, photosynthesis, respiration and cell function using one dataset.

Kaiako planning snapshot
- Core preparation: assign the numbered learner sheet and portfolio section named in each lesson; use the matching answer guidance in the kaiako guide.
- Access: allow written, oral or diagram-supported explanations while retaining the requirement for explicit biological connections.
- Practical choice: the supplied simulated datasets make the sequence teachable without wet-lab access. Microscopy or agar-cube work may be added where equipment, safety and time allow.
- Moderation: treat the portfolio as formative evidence. Use current NZQA schedules for any formal assessment decision.
