The five main types of plant tissues are:
1. Epidermal tissue (protection, water regulation)
2. Ground tissue (support, storage, photosynthesis)
3. Vascular tissue (transport of water, nutrients, and sugars)
4. Meristematic tissue (growth and development)
5. Protective tissue (mechanical support, protection)
Each tissue has specific functions crucial for plant growth, support, nutrient transportation, protection, and development.
