Do angiosperms have a resin duct?

Answer 1

• Resin ducts are always known to be present in Conifers as a reaction to wood injuries and prevent pathogenic attacks. Angiosperms also have resin ducts but very rare. One example is the genera Bursera from the family Burseraceae. They are native in some part of US and Southern America. The Burseraceae family consists of shrubs and trees growing mostly in Mexico. Another example is the genera Helianthus which is composed of sunflower species that grows annually in North and South America. Some of its species are also cultured and are also found in some of the Asian countries.

Answer 2

No, angiosperms do not have resin ducts. Resin ducts are typically found in gymnosperms, such as pine trees, where they play a role in defense against herbivores and pathogens. Angiosperms have different mechanisms for defense and protection, such as producing secondary metabolites or using physical barriers like thorns.
