Specialised Cells and Their Functions | KS3 & GCSE Science

KS3 and GCSE science (Years 7–11): specialised cells and their functions. Why can one nerve cell reach from your spine to your toes, when a red blood cell is far too small to see? Learn nine specialised cells, and how each cell's shape and parts fit its job. In this lesson: • Last time's mystery cell: the root hair cell, a plant cell with no chloroplasts • What "specialised" means: every cell has a job (its function), and features that fit it • In a plant: root hair cell, palisade cell and guard cells • In your body: red blood cell, nerve cell, muscle cell and ciliated cell • Making new life: sperm cell and egg cell • Two myths: every plant cell has chloroplasts (it doesn't), and a cell with no nucleus isn't a real cell (a red blood cell is) • Recall: name the covered cells and their jobs • Your one thing to try: how does oxygen get from your lungs into your blood?
