|---|---|---|
| Epithelial tissue | Covers body surfaces, lines organs, forms glands | Skin, stomach lining, lung lining |
| Connective tissue | Supports, connects, and binds other tissues | Bone, blood, cartilage, tendons, fat |
| Muscle tissue | Contracts to produce movement | Skeletal, cardiac, and smooth muscle |
| Nervous tissue | Transmits electrical signals | Brain, spinal cord, peripheral nerves |
Plant tissues:
- Meristematic tissue actively dividing cells at root and shoot tips
- Permanent tissue vascular (transport) and dermal (protection) tissue
Hierarchy of life:
