AN INVESTIGATION INTO THE EFFECT OF WAVE EXPOSURE ON THE MORPHOLOGY OF FUCUS VESICULOSUS (BLADDER WRACK) Introduction This investigation is on the effect of wave exposure on the morphology of the seaweed Fucus vesiculosus, commonly known as bladder wrack. Fucus vesiculosus is a common seaweed, found in the Atlantic, which is made up of a holdfast, midrib and fronds. It also has bladders to aid buoyancy so that the plant can float on the surface of the water and get light for photosynthesis. Photosynthesis is not only used for growth, but also for the development of the holdfast, which uses carbohydrates not used up in the synthesis of starch. From a previous pilot study of a transect along a rocky shoreline, it is known that Fucus vesiculosus always grows on the mid zone of rocky shores (see appendix). This is because the water levels are too high on the lower shore,...
