Pitcher plant can grow in nitrogen deficient soil.

  1. True

  2. False
Reveal answer Fill a bubble to check yourself
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'.

  2. Drosera

  3. Utricularia

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

B Correct answer
Explanation

Carnivorous plants typically grow in nutrient-poor, boggy soils where nitrogen is scarce. They capture insects to obtain nitrogen for protein synthesis.

Plants that grow in nitrogen deficient soils and swampy and boggy places are called 

  1. Epiphytic

  2. Insectivorous

  3. Saprophytic

  4. Parasitic
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
A.Epiphytic - Plants which grow on the branches of big trees for light and shelter. These plants are not connected to soil directly.
B.Insectivorous plants - Plants, trap, kill and digest insects are called insectivourous plants. They grow in nitrogen deficient soils. So, to get nitrogen the kill and digest the insects.
C.Saprophytic - Organisms, grow on the dead bodies to get food.
D.Parasitic - relationship between two species of plants or animals in which one benefits at the expense of the other, sometimes without killing the host organism.
So the correct option is 'insectivorous'.
