The surface of this structure has sculpture elements which hold proteins in place on the outer layer known as the sexine. That layer is separated from the inner layer by the columella. Individual ones have a vegetative and a generative cell. This microgametophyte (MY-kro-guh-MEE-toe-"fight") contains both a generative nucleus and a tube nucleus. It forms a namesake tube to the (*) ovules and is itself released from the anthers. For 10 points, name this type of particle containing male plant gametes which insects help move around.
