Explain that an organ is made from different tissues working together to perform a function.

An organ is made from different tissues working together to perform a function. Principles of organisation sits within Principles of organisation, so this idea should be explained in that specific biological context rather than as an isolated phrase. A useful term here is tissues, because tissues is a curriculum-aligned term linked to the learning objective: Explain that an organ is made from different tissues working together to perform a function. Avoid giving a vague answer instead of directly addressing: Explain that an organ is made from different tissues working together to perform a function; instead answer by clearly explaining how to explain that an organ is made from different tissues working together to perform a function. Use precise biological vocabulary when you explain how to explain that an organ is made from different tissues working together to perform a function. This keeps your answer tightly aligned to the approved learning objective for Principles of organisation.
