How do drosera trap the insects?

Drosera, commonly known as sundews, trap insects using their specialized glandular leaves covered in sticky, glandular hairs called trichomes. When an insect lands on the leaf, these hairs secrete a粘性粘液 that immobilizes the prey. The movement of the insect triggers additional responses, causing the leaf to curl and further ensnare the insect, allowing the plant to digest it and absorb nutrients. This adaptation helps sundews thrive in nutrient-poor environments.
