Answer Key / Explanation : (c) -

(c)

Utricularia  or bladderwort is an insectivorous submerged aquatic plant. In which the rootless floating stem bears highly dissected leaves. A portion of leaf is modified into sac, like bladders of about 1.3 mm in diameter. Each bladder is guarded by a small valve which opens inwardly. Small insects flow into the bladder with water, but cannot come out due to the volve.
