Functions of the Stem:

• Support: Holds up leaves, flowers, and fruits to receive sunlight and air.

• Hard and Woody: Found in trees and shrubs like mango and rose.

Special Features of Some Stems:

• Climbing Stems: Help plants like vines to climb.
• Modified Stems: Some stems become thorns or store food, e.g., cactus and ginger.
