Adaptations for Survival
- Prop roots (exposed roots) in mangrove plants help to stabilize the plant and absorb oxygen from the air.
Respiratory System
- Pneumatophores (respiratory or 'knee' roots) in mangrove swamps allow plants to breathe by bringing oxygen from the air into the roots.
Flower Characteristics
- Mangrove flowers are typically yellow or cream-colored.
Growth Patterns
- Mangroves usually grow up to 10-15 meters (30-45 feet) tall.
