Members of Phaeophyceae possess air bladders to provide buoyancy eg. Kelps. It helps the blades of the algae to float on the surface of the ocean and absorb sunlight for photosynthesis.

Holdfast, stipe and frond, these structures are present in
1 Dictyota
2 Laminaria
3 Fucus
4 All of these
Explanation:
The plant body of brown algae is usually attached to the substratum by a holdfast, and has a stalk, the stipe and leaf like photosynthetic organ – the frond. Laminaria, Dictyota and Fucus are all brown algae.

The vegetative cells of brown algae have a
1 Inner - cellulose, outside- coating of algin
2 Inner - mannitol, outside- coating of algin
3 Inner - laminarin, outside- coating of algin
4 Inner - pectose, outside- coating of algin
Explanation:
The vegetative cells of the members of phaeophyceae have a cellulosic wall usually covered on the outside by a gelatinous coating of algin.
