Adaptation in plants of snowy regions:
Plants in snowy regions, like pine and deodar trees, have a cone-like shape with sloping branches. This helps the snow slide off easily, preventing the weight of snow from breaking the branches.
- The branches of these trees are slanted downward, which helps in shedding snow and avoiding damage due to heavy snowfall.
- These trees have thick bark that acts as insulation, helping the tree withstand extremely cold temperatures.
- The leaves of conifers are shaped like needles, which reduce water loss and help the plant survive the cold, dry air.
