👉 Pyrophleps is a type of plant cell that produces large amounts of toxic gas when activated by light, such as from burning or heating processes. This gas is known as pyrethrin and serves as an important defense mechanism in plants to protect themselves against herbivores and pests. Pyrophleps are found primarily in the leaves of various plants, including those belonging to the family Fabaceae (including rosemary, lavender, and sweet willow).
