Match List I with List II and select the correct answer using the codes given the lists.

List-I List-II
a. Deciduous forest tree $1$. Tectona
b. Conifer $2$. Junipems
c. Palm $3$. Borassus
d. Aquatic microphyle $4$. Lemna
  1. A-$1$, B-$3$, C-$4$, D-$2$
  2. A-$1$, B-$2$, C-$3$, D-$4$
  3. A-$2$, B-$1$, C-$3$, D-$4$
  4. A-$3$, B-$2$, C-$1$, D-$4$
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Matching the items correctly: Deciduous forest tree corresponds to Tectona (teak, 1), Conifer corresponds to Junipers (2), Palm corresponds to Borassus (3), and Aquatic microphyte corresponds to Lemna (4). Thus, the correct sequence is A-1, B-2, C-3, D-4.

  3. Hydrophytes

  4. Xerophytes
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Xerophytes are plants specifically adapted to survive in environments with little liquid water, such as deserts or ice-covered regions. Lithophytes grow on rocks, mesophytes in moderate conditions, and hydrophytes in water.

Which combination of the statements is incorrect for the adaptation in cactus?

  1. The cactus plants store water in their stems which carries out photosynthesis and is covered by the cuticle.

  2. Spines are the modified leaves of the cactus plant. Which reduce the loss of water through transpiration.

  3. The cactus plants have very short roots which cannot properly absorb water from the soil.

  4. The cactus plants lose a huge amount of water through transpiration so they cannot survive in deserts for a long time.
Reveal answer Fill a bubble to check yourself
C,D Correct answer
Explanation

The succulent stem of the cactus plants usually store water and carry out photosynthesis also. The cactus stem contains a tough and waxy outer layer, called cuticle. The cactus plants possess modified leaves shaped like thin spines or thorns that decrease water loss through transpiration. 

The cactus plants contain long roots that efficiently absorb water from the ground. Due to the low transpiration rate, the cactus plants can remain alive in deserts for a longer period of time. 
So, the options C, The cactus plants have very short roots which cannot properly absorb water from the soil and D, The cactus plants lose a huge amount of water through transpiration so they cannot survive in deserts for a long time are incorrect for the adaptation in cactus.
