Question

Trees on the mountain are cone-shaped, with sloping branches and needle-shaped leaves. This helps:

• A. the rainwater and snow to slide off easily from the leaves.
• B. the leaves to absorb rainwater and snow.
• C. in increasing the rate of transpiration.
• D. in reducing the rate of transpiration.

Answer 1

The correct option is A the rainwater and snow to slide off easily from the leaves.

Plants use a wide variety of physical adaptations. Trees growing in the mountain region are cone-shaped and have slopy branches. These characteristics help slide off rainwater and snow easily from the leaves and thus prevents the snow from accumulating on the trees. The needle-shaped leaves also reduce the rate of transpiration by reducing the surface area.
