- Guard cells surround stomata on the surface of leaves. A new herbicide targets the function of guard cells and prevents them from becoming flaccid and closing the stomata. What effect would the herbicide have on plants? a.Plants would dry out because guard cells protect the epidermis against desiccation. b.Plants would be eaten because guard cells protect leaves against herbivores. c.
