Which of the following is the major adaptation for a plant to survive in the xerophytic conditions?

  1. Long tap root

  2. Lack of stomata

  3. Spines

  4. Stipular leaves

Show answer
Correct Option: C
Explanation:

CactI are among the most drought-resistant plants on the planet, due to their absence of leaves, shallow root systems, ability to store water in their stem, spines for shade and waxy skin to seal in moisture. Xerophytes can have smaller leaves or fewer branches than other plants. An example of leaf surface reduction are the spines of a cactus. Spines also protect the plants from animals and collect moisture too.

Some plants have a habit of harbouring ants to save the plants from damage by other animals which is known as

  1. Entomophily

  2. Myrmacrophily

  3. Anemophily

  4. Hydrophily

  5. Zoophily

Show answer
Correct Option: B
Explanation:

Myrmecophily is the term applied to positive interspecies associations between ants and a variety of other organisms such as plants, other arthropods, and fungi. Myrmecophily refers to mutualistic associations with ants, though in its more general use the term may also refer to commensal or even parasitic interactions. The term myrmecophile is used mainly for animals that associate with ants.

Halophytes can grow on physiological dry soil due to

botany adaptation plant adaptation adaptation in plants plant habitat importance and classification of angiosperms aquatic plant adaptations pollination through water life in water

  1. Dry soil

  2. Excessive humidity outside

  3. Excessive salts in plants

  4. Excessive salts in water

Show answer
Correct Option: C
Explanation:

Halophytes grow in physiologically dry soil. The soil is having water but the soil solution has a high concentration of salts. Thus, the water is not easily available to plants, because water flows from a region of high water potential to a region of low water potential. 

Excess salt in soil solution means the water potential of soil solution is very less. To counter the reduction in water potential in the soil solution, the halophytes maintain a highly concentrated cell sap. So, the concentration of salt is very high in these plants.
So, the correct answer is option C.

Which one is a xerophyte?

  1. Capparis

  2. Lotus

  3. China Rose

  4. Casuarina

Show answer
Correct Option: A
Explanation:

Capparis decidua (family Capparidaceae) is commonly known as kair. It is 
distributed throughout the arid regions of India and other countries. Kair is a caducous plant, so in the foliage condition mainly stem and fruits are common. It is also known as Capparis aphylla.
Since the plant is xerophytic, it is generally found in dessert area and is highly draught resistant plant, which can survive for long. Tribal people prepare pickle from the fruits of kair. 

The plants in which vascular tissues are absent and well developed aerenchyma is present are

  1. Xerophytes

  2. Halophytes

  3. Hydrophytes

  4. Mesophytes

Show answer
Correct Option: C
Explanation:

Hydrophytes are water loving plants and grow in aquatic environments. In these plants mechanical tissue is absent. Xylem is poorly developed or absent. Hydrophytes possess special air storage parenchyma, called as aerenchyma. It makes plant parts light, spongy and flexible.
