          1. Examples of plant tissues including: epidermal tissues, the outer layers which cover the whole plant, mesophyll, between two epidermis layers, where most photosynthesis happens, xylem and phloem, which transport substances around the plant eg sugars like sucrose and glucose, minerals and water.
