What happens to deciduous trees ?

The correct answer is Lose their leaves in winter.

Key Points

• Deciduous trees shed their leaves during winter or dry seasons to conserve water and energy.
• The shedding of leaves helps prevent water loss through transpiration, especially when water is scarce or frozen.
• During this period, the trees enter a state of dormancy, slowing down their metabolic activities.
• The process is triggered by changes in environmental factors such as shorter daylight hours and cooler temperatures.
• Examples of deciduous trees include oak, maple, birch, and elm.

Additional Information

• Transpiration: The process by which plants lose water vapor through small openings called stomata in their leaves.
• Dormancy: A survival mechanism in which plants temporarily stop growing and conserve resources during unfavorable conditions.
• Chlorophyll Breakdown: As leaves prepare to fall, chlorophyll breaks down, revealing other pigments like carotenoids and anthocyanins, which cause the vibrant autumn colors.
• Abscission Layer: A specialized layer of cells forms at the base of the leaf stem, facilitating leaf detachment without damaging the tree.
• Evergreen Trees: In contrast, evergreen trees like pines and spruces retain their leaves year-round and adapt differently to conserve water.
