Trees shed their leaves to take a little nap during winter! 🌳💤 When it gets cold, trees need to save energy, so they drop their leaves and rest until spring comes.
Leaves are like little blankets for trees. But in winter, they would freeze, so trees let them go and grow new ones when it's warm again! 🌞
Trees shed their leaves to survive the cold winter months. 🍁❄️ Leaves help trees make food using sunlight, but in winter, there’s less sunlight and water can freeze. So, trees drop their leaves to save energy and water!
Before the leaves fall, they change color because the tree takes back important nutrients. That’s why autumn leaves are so colorful! �
Trees shed their leaves as part of a survival strategy called abscission. 🍂 In autumn, shorter days and cooler temperatures signal trees to prepare for winter. The tree forms a special layer of cells at the base of each leaf stem, cutting off nutrients and causing the leaf to fall.
This process conserves water (since frozen water in leaves could damage the tree) and energy (as photosynthesis slows in low light). Deciduous trees—like oaks and maples—do this, while evergreens (e.g., pines) have waxy needles that resist freezing.
Before falling, leaves break down chlorophyll (the green pigment), revealing yellow/orange pigments (carotenoids) and sometimes red (anthocyanins, produced in bright autumn light).
