Epidermal Tissues, Palisafe Mesophyll Tissues, Spongy Mesophyll Tissues, Meristem Tissues 1 of 9 What does the epidermal tissue do? It is has a waxy layer that reduces water loss to evaporation 2 of 9 What does the upper epidermis do? It is transparent so that light can pass through to the palisade layer 3 of 9 What does the palisade layer do? It contains a lot of chloroplast that allows for the plant to photosynthesise 4 of 9 What does the lower epidermis do? It allows for efficient gas exchange and means CO2 to diffuse directly into the leaf 5 of 9 What does the Epidermal tissue do? This covers the whole plant 6 of 9 What does the Palisade Mesophyll tissue do? This is where the photosynthesis in the plant 7 of 9 What does the Spongy Mesophyll tissue do? Contains big air spaces to allow gases to diffuse in and out of cells 8 of 9 What does the Meristem Tissue do? This is found at the growing tips of roots and is able to differentiate into lots of different plant cells 9 of 9
