Choose the type of plant for every adaptive feature given in a, b, c, d, e and f from the list given below:

Answer 1

• Desert plants have small or spine-like leaves and thick waxy stem so that they can prevent the loss of water by transpiration.
• Mountainous plants have sloping branches and cone-shaped structure that helps to get the snow to fall off the tree quickly and to get the sunlight.

Therefore, the given features can be related to the plants as:

(a) Thick waxy stem - desert plant

(b) Short roots - aquatic plant

(c) Cone-shaped plants - mountainous plant

(d) Sloping branches - mountainous plant

(e) Small or spine-like leaves - desert plant
