Cells & Tissues
Biology: AQA GCSE Higher, topic 2.1.1
Tissues
Cells are the fundamental units (building blocks) that make up all living organisms. Tissues are groups of similar cells that act together to perform a similar function. Examples of tissues are:
Epithelial tissue (animals & plants)
- Epithelial tissue lines the outer surface of organs and blood vessels.
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.
