what happens when there is nitrogen! scarity in pitcher plant​

Answer 1

Answer:

Explanation:

Insect carnivorous plants such as pitcher plants and sundews (Nepenthaceae/Sarraceniaceae and Drosera respectively) are able to obtain substantial amounts of nitrogen from the insects that they capture.

                                       The leaves possess specialized structures, referred to as glandular trichomes, which consist of an elongated stalk with a glandular tip that secretes a sticky, polysaccharide-rich mucilage. (Barthlott 2007). These trichomes have a red pigmentation that attracts insects, which are caught in the mucilage when they land on the leaf. As the insect struggles to escape, the trichomes respond by releasing more mucilage until the insect is consumed by it. Then the trichomes turn inward, pushing the insect to the horizontal center of the leaf. This response by the trichomes is activated by mechanical stimulus and is relatively rapid, starting as soon as a few seconds after stimulation and enduring for a few minutes. The response is considered to be nastic because the direction of the response is always toward the center of the leaf, independent of the location of the stimulation
