  4. Both A and B

Show answer
Correct Option: C
Explanation:

Rhizophora is a genus of tropical mangrove trees. It occurs in Mangrove forests. It is also called as true mangrove. These are found in coastal intertidal zone. They are adapted to live in harsh environmental conditions. Thus, the correct answer is 'Mangrove.'

  1. Alpine trees

  2. Mangrove plants

  3. Grass

  4. Fir forests

Show answer
Correct Option: B
Explanation:

Sunderbans contain mainly mangrove plants. These are the mangrove area in the region of bay of Bengal. They have a thick canopy. The name is derived from the Sundari, the local name of the mangrove species Heritiera fomes.

  1. $500$ mya

  2. $350$ mya

  3. $320$ mya

  4. $200$ mya

Show answer
Correct Option: A
Explanation:

Invertebrates were formed and active approximately 500 million years ago (mya). Jawless fish existed around 350 mya; while, sea weeds and few plants evolved approximately 320 mya. Dinosaurs extinct approximately 65 mya. 


So, the correct answer is option A.

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

botany ecological adaptations, succession and ecological services extreme adaptations adapting to a habit adaptive features aquatic plant adaptations pollination through water

  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.

Show answer
Correct Option: C,D
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.

  1. Xerophytes

  2. Gametophytes

  3. Mesophytes

  4. Hydrophytes

Show answer
Correct Option: A
Explanation:

Stomata in xerophytes open in night and remain close during day to prevent loss of water through transpiration.

"Patther phul" is _______________.

botany ecological adaptations, succession and ecological services extreme adaptations adapting to a habit adaptive features aquatic plant adaptations pollination through water

  1. Lichen

  2. Xerophytic plant

  3. Living stones

  4. Hydrophytic plant

Show answer
Correct Option: B
Explanation:

"Patther phul" or stone flower or rock moss is a xerophytic plant or xerophytic shrub occurring wild on rocky ground( not much water present) As it is a plant which needs very little water it is called a xerophyte and occurs in the region of Gujarat 

So, the correct answer is 'Xerophytic plant'.
