B. Match the type to the description.

1. cell
2. tissue
3. organ
4. organ system
5. organism

different tissue types working together
different organs working together
basic unit of life
composed of many organ systems

C. Tissues: cells held together by fibres or sticky materials

1. muscle
2. nerve
3. connective
4. epithelial

covers the surface of organs and the body; lines the inside of body parts
transfers signals between organs
helps body movement and helps some organs work (e.g. heart)
