Digital file -Notes: Year 7 & 8- Levels of Organisation and Specialised Cells

This booklet is based on the Science Programmes of Study: Key Stage 3, National Curriculum in England. It focuses on the hierarchical organisation of multicellular organisms, from specialised cells to tissues, organs, organ systems, and whole organisms.

Inside, you’ll learn how to:

• Identify and describe specialised cells and their functions, with examples such as red blood cells, nerve cells, leaf cells, and root hair cells.

• Understand how cells combine to form tissues.

• Explore how tissues work together to form organs.

• Examine how organs are organised into organ systems.

• See how organ systems function together to support the whole organism.

• Apply your knowledge to observe patterns of organisation and understand the link between structure and function.

This booklet will help you build a clear understanding of how living organisms are organised, how specialised cells contribute to the function of tissues and organs, and how each level of organisation supports the life of the organism.
