20-question review bank. Choose about four questions for the short review slot; use the others for retrieval later, or replace earlier discussion time with a longer round. Numbered buttons open any question. Optional items are labelled and may be skipped.
Original, accessible practice inspired by the current OCR GCSE Biology A (Gateway Science), J247 · specification v4.0 (August 2026). These are teacher-written questions, not official OCR exam items. Explanations follow every choice.
40 minutes. Context 5; key words 4; animal cells 8; plant cells 7; match 6; explain 4; check 4; exit 2. The optional 07.5 atlas adds 6 minutes, or replaces the 6-minute matching activity to keep the session at 40 minutes. Choose a few examples; the core quiz does not test atlas-only detail.
Keep the same question throughout: What is its job? Which feature helps? How does it help? Invite pointing, speaking or a quick sketch. Read the captions aloud. Model one explanation, build the next together, then let pupils try.
Core words: specialised, adaptation, function. Introduce other cell names beside their models. The DNA, differentiation and stem-cell detail in Explain it is optional; the core check does not test it.
Allow about two minutes per animal cell, then revisit the hardest example. For plants, compare a root hair cell with a palisade leaf cell. Do not imply that every plant cell has chloroplasts. Adult human red blood cells have no nucleus. Haemoglobin is the protein that carries oxygen.
The interactive models are illustrations, not micrographs. Chapter 07.5 uses real microscope photographs, with staining or added colours explained in the captions. Colours, transparency and sizes are for teaching; models are not shown at the same scale. The root hair is a cell extension, not a separate root. Muscle cells release energy through respiration; they do not create energy.
Knowledge: I explore how specialised cells are suited to their jobs.Skill: I link a cell’s features to its job.
This revised lesson focuses on specialisation. It is not a complete lesson on stem cells or medical treatments.
Planning reference: Oak National Academy · Specialised cells are adapted for their functions. Activities and wording adapted for this class; original interactive models.
