B Correct answer
Explanation
$\to$ Dischidia / Monotropa. 
$\to$ Monotropa is a genus of 5 species of herbaceous perennial flowering plants, formly classified in the family Monotropaceae, but now included with most the Ericaceae. 
$\bullet$ unlike most of the plants, they do not contain chlorophyll.
$\bullet$ They are myco - heterotrophs, getting their food through parasitism upon fungi rather than synthesis.
$\bullet$ Thus, they are capable of living in very dark conditions.

In which type of soil pitcher plants can grow?

  1. Phosphorus deficient soil

  2. Potassium deficient soil

  3. Nitrogen deficient soil

  4. None of the above
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Carnivorous plants like pitcher plants are having a trapping mechanism designed to catch and digest insects. They do this to obtain the nutrients not found in the soil. They derive nitrogen from the prey they trap and thus they can grow in nitrogen-deficient soil.

The correct option is C.

A Correct answer
Explanation

A) Carnivorous plants like pitcher plant have a trapping mechanism designed to catch and digest insects. They do this in order to obtain nutrients not found in the soil. They derive nitrogen from the prey they trap and hence, can grow in nitrogen deficient soil.

B) Pitcher plants can grow in nitrogen deficient soil.
So the correct answer is 'True'.

  1. Monotropa

  2. Drosera

  3. Utricularia

  4. Nepenthes
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Monotropa is not an insectivorous plant but is a saprophytic plant because it feeds by soaking up necessary nutrients from surrounding decaying plant matter. The other given plants are examples of insectivorous plants

So, the correct option is 'Monotropa'.

Insectivorous plants trap insects to 

  1. Meet their potassium requirements

  2. Meet their nitrogen requirements

  3. Meet their phosphorous requirements

  4. Meet their oxygen requirements
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Insectivorous plants trap and digest insects and other small animals to obtain the nitrogen that is required for their growth. Most plants absorb enough nitrogen from nitrates in the soil but as the insectivorous plants live in nitrate-deficient bogs, they need to fulfill their nitrogen demand by digesting the prey instead. 

So the correct option is 'Meet their Nitrogen requirements'

  1. sulphur

  2. nitrogen

  3. potassium

  4. phosphorus
Reveal answer Fill a bubble to check yourself
B Correct answer
