Question

A small rootless aquatic herb in which a portion of leaf forms a tiny sack or bladder which traps water insects is

• A. Dionaea
• B. Utricularia
• C. Sarracenia
• D. Drosera

Answer 1

Answer: (B)

Utricularia

Utricularia are carnivorous plants which capture small prey with remarkable suction traps. These are rootless plants formed of very thin, forked leaves. Only the flower remain out of the water while the whole trap is underwater. When an aquatic animal touches its sensitive hairs, the traps suck it in, in just a few seconds, along with water, which is then drained through its walls.

So, the correct answer is " Urtticularia ".
