Cells, Tissues, Organs and Organ Systems — Interactive Lesson (Ages 11–14)

Trillions of cells, one body. Show pupils how cells team up to build a whole organism. This 19-slide interactive lesson on levels of organisation takes pupils from first ideas to exam-style explanations, with 10 self-marking activities and nothing to prepare beforehand.

Teaching Cells, Tissues, Organs and Organ Systems in KS3 Science

Pupils tell unicellular from multicellular organisms, match specialised cells such as red blood cells, nerve cells and root hair cells to their jobs, and put cell, tissue, organ, organ system and organism in order of size. They match organs to the digestive, circulatory, respiratory and nervous systems and identify tissues and organs in plants.

What Pupils Will Learn

• Tell unicellular and multicellular organisms apart.
• Describe how some cells are specialised for a job.
• Put the levels of organisation in order: cell → tissue → organ → organ system → organism.
• Name major organ systems and the organs in them.
• Give examples of tissues and organs in plants.
