Guard cells are cells that make up the stomata which is responsible for the exchange of gases in the pores. The Plant cuticle is the first structure to prevent water loss in the leaf. This is due to specialised surface properties. Spongy mesophyll re the loosely packed photosynthetic cells. The high percentage of sugar produced is found in the phloem sap
