Which of the following are characteristic features of trees in mountain range A) sloping branches B) needle like leaves C) waxy, thick stem D) long penetrating roots?

Option 1 : A & B

Concept:

• Adaptation refers to the presence of specific features and habits which enable a plant or animal to live in a particular habitat and its geographical conditions.
• Adaptation is long term gradual and continuous process.
• Habitat refers to the surroundings where plants and animals live.
• The plants or trees species survive in their environment such as underwater, in deserts, on grassland, on the mountain range, etc 
• For example, seaweed is a plant adapted for its underwater environment, cacti are adapted for a desert environment, conifers plants are adapted for a snowy environment, etc.

Explanation:​

• Characteristic features of trees in the mountain range:
  • Plants or trees such as pines, firs, spruces, etc are adapted for a mountain environment.
  • These trees are tall. straight and have cone-shaped.
  • They have sloping branches so that snow slides off easily without damaging the branches and leaves.
  • The leaves are needle-shaped with a wax-like coating.
  • The trees have thick bark which helps the tree to withstand the cold.
• Whereas the desert plant has a waxy coating on the stem which helps to retain water as well as long penetrating roots for absorbing water.

Therefore, from the above discussion, we can say that the correct answer is A & B.
