Detailed explanation-1: -(c) Phaeophyceae In the members of class-Phaeophyceae, the plant body is usually attached to the substratum by a hold fast and has a stalk called stipe and a leaf like photosynthetic organ called frond.

Detailed explanation-2: -Fronds are leaf-like structures. All these structures are part of the plant body belonging to the class of brown algae.

Detailed explanation-3: -The part of kelp most similar in appearance and location to the roots of plants is called the holdfast. This spaghetti like structure has a primary function of securing the organism to the sea floor; holding it “fast” in all but the most turbulent conditions.

Detailed explanation-4: -Phaeophyceae (brown algae) are eukaryotic marine algae. The body consists of branched filamentous structure in lower forms (e.g., Ectocarpus) and parenchymatous structure in higher forms (e.g., sargassum). The plant body is often differentiated into holdfast, stipe and lamina (frond).

Detailed explanation-5: -In the class phaeophyceae of algae, the plant body is usually attached to the substratum by a holdfast, and has a a stalk, which is termed the stipe, and a leaf-like photosynthetic organ called the frond.
