E) Rhizoid.

Quizplus · Accepted Answer

The stipe is the stem-like structure of kelp that can grow more than 50 m long, providing support to the blades and gas bladders.

Answer: A and D are incorrect because the blade is the leaf-like structure of kelp, while the gas bladder is a floatation device providing buoyancy to the kelp. B and E are also incorrect because the holdfast is the root-like structure that anchors the kelp to the substrate, and the rhizoid is a filamentous structure that absorbs nutrients from the surrounding water.
