Cells are the fundamental units (building blocks) of all living organisms. Tissues are groups of similar cells that act together to perform a similar function. Examples of tissues are:
Epithelial tissue (animals and plants)
- Epithelial tissue comes into contact with the outside world.
Muscular tissue (animals)
- Muscular tissue can contract to bring about force and motion.
Mesophyll (plants)
- Mesophyll is capable of photosynthesis.
Epidermal tissue (animals and plants)
- Human skin, and the waxy covering of some plants are examples of epidermal tissues.
