Roots, shoots, and leaves all contain three basic types of tissues:
1. dermal tissues
2. ground tissues
3. vascular tissue
Dermal tissue includes the epidermis. The epidermis forms an outer protective covering for the plant. It is one cell layer thick in most plants.
Ground tissue includes the cortex of the stem and mesophyll of leaves. Ground tissue cells function in storage, photosynthesis, and secretions.
Vascular tissue conducts fluids and dissolved substances throughout the plant body.
