There are 4 nitrogenous bases in DNA. Adenine pairs with thymine, and Guanine pairs with cytosine. A Dna Nucleotide consists of a 5 carbon sugar, a phosphate group and a nitrogenous base. These bases are paired up by weak hydrogen bonds, so when they have have to replicate, the enzyme helicase can easily unzip the Dna. <span />

Complete question: While taking a walk in a park, Muskaan observed an insect on a pitcher plant (Nepenthes). Immediately the flower opened up and the insect slid down. To which of the following categories does the pitcher plant belongs?

a) Saprophytes

b) Insectivorous

c) Parasite

d) Symbiotic

Answer:

The correct answer is option b. Insectivorous

Explanation:

A carnivorous or insectivorous plant is the one that obtains most of its nutritional necessities from the capture and consumption of protozoans or animals, especially insects and arthropods.

These insectivorous plants grow in poorly nutritional soil, so they need to get nutrients from their prey. These species attract and trap their prey, and by the action of specific enzymes and digestive bacterias, they can absorb the insects' nutrients.

These insectivorous plants make use of their flowers to trap the prey. These tramp flowers are cup-shaped, and at the bottom of this cup, there is a liquid where insects get trapped and die.

Insects are attracted by aromas produced by the edges of the trap and when they land, they slip and fall inside, and once drowned, the enzymes digest them.
