Which of the following is NOT an insectivorous plant : Correct Answer Ageratum

The correct answer is Ageratum.

Concept:

• Carnivorous plants obtain the essential nutrients from the heterotrophs.
• These plants trap insects and obtain the nutrients which they do not get from the soil as they grow in nitrogen-deficient soils.
• They are not called heterotrophs or consumers, because they only derive nutrients from insects.
• These plants get energy from the process of photosynthesis.
• Hence they are both producers and carnivores.

Explanation:

• Some of the examples of insectivorous plants are - Drosera, Venus Flytrap (Doinea), Nepenthes, Pinguicula, Genlisea.

Here, Ageratum is not a carnivorous plant

Ageratum:

• Ageratum, (genus Ageratum), also called whiteweed, any of about 40 species of herbs in the genus Ageratum (family Asteraceae).
• Native to the Americas, but primarily in Mexico and tropical South America, Ageratum species can be annuals or perennials.
• They have toothed ovate leaves arranged oppositely along the stem.
• Similar to most members of Asteraceae, they feature composite flower heads composed of blue, pink, lilac, or white discoid flowers.
• These flowers produce small dry fruits with minute seeds.

Additional Information

• It has a Pitcher-like structure that is the modified part of the leaf.
• The apex of the leaf forms a lid that can open and close the mouth of the pitcher.
• Inside the pitcher, there are hairs that are directed downwards.
• When an insect lands in the pitcher, the lid closes and the trapped insect gets entangled in the hair.
• The insect is digested by the digestive juices secreted in the pitcher.
• It can trap and eat frogs, insects and even mice.
• It is found in Australia, Indonesia and Meghalaya in India.
• It has a pitcher-like shape and the mouth is covered by a leaf.
• It has a special smell that attracts insects to it, which get trapped and can't get out.
