Intercalary Meristem: Definition and Examples in Monocots

📚 Quick Study Guide

• 🌱 Intercalary meristems are meristematic tissues located at the nodes of certain plants, primarily monocots.
• ➗ Unlike apical or lateral meristems, intercalary meristems are specifically involved in longitudinal growth from the middle of the plant.
• 🌾 They contribute to the regrowth of plant parts that have been grazed or mowed, such as grass.
• 🧬 Common examples include grasses, bamboo, and horsetails.
• ✍️ These meristems are responsible for leaf and internode elongation.
• 🔬 The activity of intercalary meristems allows for rapid regrowth after damage.
