Photosynthesis itself does not make a plant float. However, the oxygen produced during photosynthesis can help create buoyancy by increasing the volume of air trapped within the plant's tissues, which can help certain types of aquatic plants float on the water's surface.
Seaweed has a part called a Float. This is often at the very top of the plant. The float mostly floats on the top of the water. The Float helps to keep the Seaweed buoyant. Seaweed floats because of the Float.
