The Four Types Of Seed Dispersal

Plants reproduce by asexual reproduction or pollination in most cases, they do this in order to make seeds. Seeds are the embryonic, or unborn, state of a plant. These seeds are made to carry the genetic material and make new plants. In most cases a plant wants its seeds to be spread of moved to a new place not close to the parent plant, this is done through seed dispersal. There are many types of seed dispersal for example wind, water, animals, and other biotic and abiotic factors. One of the biggest techniques of seed dispersal is wind. Plants use different types of wind dispersal. They can use gliders, parachutes, helicopters (whirlybirds), flutterer/spinners, cottony seeds & fruits, and tumbleweeds. These seeds use wind currents to carry …show more content…
Wind was chosen as the method of seed dispersal due to limitations of a school such as, water sources and not allowing animals. The wind we have chosen does not include a pushing wind but instead how our object moves in the air. In this lab the group will measure the time in the air and distance to make graphs to find the most efficient carrier. For this lab the independent variable is the height and the drop #. The dependent variable is time and distance. The control group is the seed carrier, and the constant is the drop height and place of the …show more content…
The reason for this is that without wind pushing the angle for direction did not work as planned and did not control direction or movement forward. The parachute did make the time higher but didn't work well with the weight of the glider so the hypothesis has been refuted. The data showed that the carrier nor travels far from the parent plant or stay in the air long enough to do such with only about 3 seconds and 1 meter on a good drop. This can be connected to the fact that the carriers failure is in weight and angle. From research of seed dispersal most techniques are simple, light, and built perfectly to move the seed carrier correctly. Which was failed for the carrier to be light, simple, and angled to move correctly. It can be inferred that parachutes are very efficient if done right, and that this carrier should have used less weight and take more time with precision angles. There had been multiple sources of error, one being the fact of one teammate not measuring correctly at first. The carrier had to redo the drops for another reason, the original dropper was not only launching the carrier out like a frisbee but also pulling the design apart and trying to change it in between drops. This means the drops after fixing the the problems already stated might also have been
