A complete, no-prep 100-mark worksheet on stem cells in animals — 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 stem cell types, the zygote and embryo, differentiation, induced stem cells, and bone marrow through multiple choice questions, a true/false table, and a fill-in-the-blank activity covering zygote, mitosis, genes, self-renewal, and leukemia. Section 2 (40 marks) builds understanding through a matching activity, a sequenced description from fertilisation to embryonic stem cells, an embryonic versus adult stem cells comparison table, a gene-based explanation of differentiation, adult stem cell locations and functions, red blood cell production questions, an extended response on identical DNA producing different cells, and a bone marrow transplant question. Section 3 (30 marks) challenges students with extended discussions on embryonic versus adult stem cells and induced stem cells, differentiation as a one-way process, and a full evaluation of medical uses of stem cells including ethical issues. 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.
