Cell Specialisation, Tissues and Organs
The Cell · Specialisation and Organisation
Syllabus tag: KCSE | Biology | Form 1 | Topic 3 The Cell
Lesson objectives
By the end of this topic, you should be able to:
- Explain the meaning of cell specialisation.
- Relate the structure of named specialised cells to their functions.
- Define tissue, organ and organ system.
- Arrange the levels of organisation in a multicellular organism.
Summary
In a multicellular organism, cells become specialised — modified in structure to perform one function particularly well. Specialised cells of the same kind form a tissue, tissues form an organ, and organs working together form an organ system. In every case structure is related to function, and that relationship is what examination questions test.
