Sticky Substance and Its Role in Plants:

• Wound Healing: The gum helps seal wounds caused by damage to the plant, such as cuts, breaks, or insect attacks. This protects the plant from further injury and infection.
• Protection Against Pathogens: The sticky nature of the gum acts as a barrier, preventing the entry of harmful microorganisms, such as bacteria and fungi.
• Water Conservation: When a plant is injured, the gum can prevent excessive loss of water through the damaged area.
• Deterrence of Herbivores: The sticky substance can make the plant less palatable to herbivores, deterring them from feeding on it.
• Support During Stress: Gum production may also help the plant survive adverse conditions like drought or physical damage by maintaining its structural integrity.​
