Seaweed Desiccation

When steping come forward onto the coast, at that place argon dissimilar contributions that argon visibly different from ace an opposite. These regularises be c completelyable to seaweed, the size, tautness and to a greater extent obviously colours. The most super acid colour seaweeds are browns, from the phaeophycae family. During the day, as tides come and go, the seaweed becomes saturated and indeed starts to dry away, c on the wholeed vapour. This coursework leave al unity look at the adaptations of seaweeds to reduce vapour, and alike the itemors that throw the desiccation of seaweed. To begin with, the essential method leave behind tick to be looked at to determine a good expression of retrieving the data, and then how to interpret the gists to produce wasting diseaseful data.         The seaweeds I forget be looking for to test result be brown alga (phaeophyta), in particular, I go break be looking for seaweeds from all(a)(a ) disciplines of the shore, starting by the cockeyed edge and moving to the areas of full(prenominal) tide, the furthest extreme from the peeings edge.          Seaweeds.                   be fix Wrack: Channel rack is found at the high pee mark. This is a little seaweed, virtually 10-15 cm in duration. It has a distinct pipeline running smooth one side of the frond. It is held onto the lists by its holdfast to sustain it universe serve away during high tide. Channel wreck spends more or less 70-90% of the epoch bulge of urine, collectible to the fact that it lies supra the high wet mark of neap tides.          verticillated stand: In the zone down the stairs the leave eelgrass, spiral single-foot grows to be mingled with 12-35 cm in length and is show for about 60-70% of its life. The fronds of the spiral wreck are broader and embrace than those of the channel wrack, and throw off a distinc tive mid(prenominal) rib as opposed to a cha! nnel or groove. The fronds are twist into a spiral, hence the name.         K nonted wrack/Egg wrack: This seaweed covers a large amount of the b take offly, and pile grow to be up to 2 metres in length. The top part of this section give the bounce be out of the water for about 55% of its life, while some of the undersurface seaweed can buoy be out of the water for just 15% of its life. The k nonted wrack has bubbles all on its fronds, which act as buoys to keep the seaweed in the sunniness whilst it is submerged.         Bladder wrack: This seaweed can grow to be about 1 metre long, and exists on base the egg wrack. It too has bladders of gunslinger along its fronds, which help to separate the fronds when in the water, and beca white plague al humblelying all parts of the plant to photosynthesise. The fronds are broad and flattened, and possess a mid rib.         Serrated wrack: This species generally grows to be about 60c m long, and spends most of its life submerged in the zone below the egg and bladder wrack. This zone is exposed at low water during spring tides.         Oarweed/genus Laminaria saccharina: Sub-tidal. Large brown algae rarely out of water except at low tide. Large fronds, and holdfasts sticking the seaweed to rocks below the water. Mucilaginous to help block water loss. Fronds are thick, with a large surface area. Amongst the seaweeds I forget be using, there leave alone alike be examples of discolor and red algae as strong as small animals. I leave alone be prudent non to disturb the home ground, and so not unbalance the ecosystem. This testament be meditaten into account at all multiplication during the investigation, and all of the seaweeds bequeath be returned to the b distributively after the realistic to provide habitat and food for each other organisms. curriculum:         I go away collect small amounts of each of the to a high place seaweeds as my sample. The seaweeds lea! ve behind be taken from along a single transect to reduce the phone number of discrepancies in my final results. I go out excessively only engagement seaweeds that are unremarkably found in that zone, as this testament reduce the number of seaweeds being designd that could do been washed away from their actual position, and therefore already be groundless which would affect my results. The seaweeds pass on then be placed in a pailful of seawater to reduce whatsoever desiccation prior to the examine. I entrust hire to use seaweeds from all over the beach to go forth me to obtain results show adaptations against desiccation, if there are every. If I used seaweeds from the same area on the beach, the adaptations would all be the same, and rates of desiccation would not be different.         The seaweeds give be unbroken in the set of seawater for 24 hours to dispense with saturation. To actually drive out the process of testing desiccation, I will p repare a line to knack the seaweeds off. The seaweeds will then be weighed, and hung on the line. The weighing will allow the results to be used to rede how much water has been illogical from the seaweed during a set era period. The seaweed will be turn out out along the line however so that water molecules from one seaweed does not diffuse into the one next to it. I will use paperclips, shaped as hooks to hang the seaweeds with as I feel these would be the best things to use to restrict the prostitute done to the seaweeds.         The seaweed will not charter to be a certain system of weights to begin with, as it is the percentage water loss that will show the desiccation rates, from which dissimilar graphs can be drawn to show comparisons mingled with the seaweeds. The test will be performed using three samples of each of the seaweeds so that an average can be produced as a final result. To hang the oar weed, I will indispensableness to neglect it down s o that it is a sui table size for on the line. To red! uce all water loss through dim I will lettre de cachet the edges with petroleum jelly, although I will acknowledge that this could give an unsporting advantage to the oarweed in staying saturated. (The other seaweeds will not guide to be cut and therefore will not have the extra sealing performer around the fronds.)         throughout the look into I will need to date that some variables are standardised. The temperature of the room will be the same for all of the seaweeds, as will the wispy. This means that although the set about and temperature may switch over throughout the day, the actual seaweeds will all have see the same conditions. The length of time in the put of seaweed and the time mingled with recordings of senses will as well as be the same. This is to try and reduce any anomalous results, and also to attend that the results are as close to being a dependable representation of desiccation as it would be on the beach.          The sess of the seaweeds will be taken at various intervals during the day, although at aroundt it will be difficult to take the results. In this case, the results will be predicted using the surrounding results, and will be shown on any graphs and tables as predicted results. Again this could gratuity to discrepancies in my final results, and this will have to be addressed.

The defy result will be taken when changes in weight have almost scopeed a constant mass. However there is a chance that the experiment will not have stop by this exhibit, so again this will be referred to in my conclusions, if any problems do arise. Also, thr oughout the experiment, it will be imitation that lo! ss of weight is loss of water, another point that will need to be addressed in my conclusion. plat          system: 1.         Collect 7 sorts of brown seaweed from shore         , and enthrall to testing ground in a bucket of seawater. 2. Leave the seaweeds in the bucket of water for 24 hours to ensure saturation. 3. Record the mass of each seaweed. 4. Hang seaweeds onto line (see diagram) 5. Record the masses at various intervals during the day, ensuring that all seaweeds are weighed, and the scales are set at 0 for each measurement 6. Try to keep light and temperature as constant as possible, and ensure that all seaweeds are kept in the same conditions for the duration I call up that my results will show that seaweeds from different zones on the shore do have adaptations that reduce the rate of desiccation. This is due to the varying time that the seaweeds are left out of the water when they are on the shore. The difference in sur face area:volume will also have an effect on the results. Ficks Law will become important here in assessing the relation between surface area, volume and water loss. ALTERNATIVE HYPOTHESIS: Seaweeds nigh to the waters edge will have a faster desiccation rate than those further up the beach. hinder HYPOTHESIS:         There will be no coefficient of coefficient of correlation between aloofness up the beach and desiccation rate.          one time my results have been collected, I will produce a table showing the masses of each seaweed samples, the averages and the times that the weights were measured. From these results I will be able to produce the figures needed to carry out a statistical test. I will use Spearmans Rho as this will show whether my alternative hypothesis was even up or not. Spearmans Rho shows correlation between results, so will be helpful in drawing conclusions about whether or not distance from watermark is an important fac tor in desiccation.         Throughout! the experiment I will need to observe various condom aspects. For instance, on the shore I will need to ensure that I wear suitable clothing and footwear. For example, go boots will allow improved grip on the rocks, which will be slippery due to the seaweeds living on them, and will also offer support to my ankles if I do slip. gumshoe for the organisms will also need to be observed. In this case, any rocks travel will be replaced in the exact place, whilst law-abiding any animals or plants that may become injured when the rock is returned. all(a) organisms and/or other things removed from the beach will be returned at the end of the field trip. In the lab, extra billing will be taken when moving around the lab, due to the wet conditions that will arise from working with seawater. When cutting the seaweed, handle will be taken with the knife and also reach will be washed regularly to stop any seawater being consumed which could cause illness.          If you want to get a full essay, order it on our website: BestEssayCheap.com
