A body is not just a bag of cells. Similar cells team up into tissues, each one doing a single job well — dividing, covering, binding, contracting or signalling. Tap each kind to see what it does.
Play with it
Plants and animals divide the work between different tissues. Tap each one to see what it is, where it sits and the job it does.

Worked example. Which animal tissue carries messages around the body?
The body's "wiring" is nervous tissue, made of nerve cells called neurons. They carry fast electrical messages from one part of the body to another. (Muscle moves, epithelium covers, connective tissue binds — only nervous tissue signals.)
Where you'll meet it
A blood transfusion replaces a fluid connective tissue; skin grafts and bone grafts move healthy tissue to where it is needed. Knowing how tissues are built is the first step in repairing them.
Trees and crops gain height at their tips, where meristematic tissue keeps dividing. Gardeners use this on purpose — pinch off the tip and the plant grows bushy instead of tall.
