Question 1 Report

Which of the following structural features adapts Drosera (Sundew) to its carnivorous mode of nutrition?
Answer Details
The structural feature that adapts Drosera (Sundew) to its carnivorous mode of nutrition is the club-shaped glandular hairs on its leaves. These glandular hairs have a sticky secretion that traps insects and other small organisms, providing the plant with the necessary nutrients it cannot get from the soil. The broad leaves with long spines and wide stomata under the leaves are not directly involved in the carnivorous mode of nutrition, while the long root with glandular hairs and prominent lenticel on the stem serve other purposes, such as anchoring the plant and allowing gas exchange, respectively.
