A complete, no-prep 100-mark worksheet on animal cell structures and their functions — ready to use for lessons, homework, or revision with KS3 Biology students aged 11-14.

Structured across three sections of progressive difficulty: Section 1 (30 marks) covers the four main animal cell structures, 3D cells, and scientific models through multiple choice questions, a true/false table, and a fill-in-the-blank activity. Section 2 (40 marks) builds understanding through matching, definition writing, diagram labelling, a cell-to-house analogy table, and structured questions on the adaptations of red blood cells and sperm cells. Section 3 (30 marks) challenges students with an extended model evaluation task, a specialised cells comparison question, and a discussion question on the role of mitochondria across different cell types. A full answer key with detailed marking guidance is included.

Also available: a companion extension pack with four enrichment activities, or save £1 with the complete lesson bundle — both listed on the iNewittAll TES store.
