Tissues
Cells are the fundamental units (building blocks) of all living organisms. New cells are produced by division of existing cells. Tissues are groups of similar cells that act together to perform a similar function. Examples:
Epithelial tissue (animals & 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 & plants)
- Human skin, and the waxy covering of some plants are examples of epidermal tissues.
