  1. Casuarina

  2. Opuntia

  3. Hydrilla

  4. Acacia

Show answer
Correct Option: B
Explanation:
Opuntia is a plant growing in dry and xeric habitats and it has a stem containing several nodes and internodes. It is modified into a flat, fleshy and thick green leaf-like structure called phylloclade. which performs the functions of photosynthesis. The leaves gets modified into spines to help in reducing transpiration.

An adaptation of plants to water scarcity and high temperature is

  1. Succulent stem stores water

  2. Poorly developed root

  3. They shed their leaves

  4. In unfavourable season, plants survive in dormant state as seeds

Show answer
Correct Option: A
Explanation:
  • Water storage in stem and tubers is an adaptation of plants to thrive in harsh environments with high temperatures and scarce water. Such plants called xerophytes usually develop succulent stems that can store water.
  • They have a very extensive root system to absorb the maximum amount of water from the soil.
  • Other adaptations include thick waxy cuticle, reduced leaf size, densely packed leaves, reduced number of stomata in pitted and grooved positions.

Vegetation of geographic region with low rainfall, high temperature, loose and sandy soil is of the type called

  1. Grassland

  2. Scrub forest

  3. Xerophytic

  4. Evergreen tropical forest

Show answer
Correct Option: C
Explanation:

Vegetation of geographic region with low rainfall, high temperature, loose and sandy soil is of the type called xerophytic vegetation. It consists of spiny shrub, cactus. Caatinga is a type of xerophytic vegetation.

Thus, the correct answer is 'Xerophytic.'
