Question

What are lectins and how do some plants use them against insects?

Answer 1

Lectins are a type of proteins found in various plants, animals, and microorganisms. In plants, lectins play a role in defense mechanisms against insects by acting as natural insecticides. Plants produce lectins that are toxic to insects when ingested. These lectins bind to specific carbohydrate molecules in the insect's digestive system, disrupting their cell membranes and causing cell death. This defense mechanism helps plants protect themselves from insect damage and potential threats to their survival.

Answer 2

Lectins are a type of protein found in plants that have the ability to bind to carbohydrates. Some plants use lectins as a defense mechanism against insects by disrupting the insects' digestive systems. When insects consume plants containing lectins, these proteins bind to the carbohydrates in the insects' gut lining, disrupting nutrient absorption and ultimately leading to the insects' death. This defense mechanism helps protect the plants from being eaten by insects.
