They can even continue their reproductive cycles. So winter is a great time to get out and explore their diversity.

Go on a moss hunt and explore the theory. Which side of the tree does it grow on? Ancient and damp, mosses are part of a group of plants known as bryophytes. There are over 1, in the UK, and some have global significance. What side of the tree does moss grow on? Natural navigation. Why does moss prefer the north side of trees? All moss cells need access to water from the environment. They need water to reproduce. The male reproductive cells need to move via a film of water to reach the female cells for fertilisation.

Sometimes this is within one plant but can also require them to reach another plant, depending on the species. If mosses dry out they are unable to reproduce, which is more likely to happen on the sunnier side of trees. Pleurococcus Pleurococcus a.

Protococcus is single celled green algae, it is found on the bark of trees but it never grows on softwood trees. It is the most common green algae in the world. It is found is all seasons and grows in moist places. It reproduces by cell division and is transported by the wind. As it is a green plant it photosynthesizes. I predict that the side with the least light will have the most Pleurococcus.

This is because if there is too much light the Pleurococcus will dry out and die, as it has no roots and the only way for it to get water is to absorb the water that runs down the tree that it grows on. All the measurements will be taken 1 metre up each tree. We will use the same type of quadrat squares and we will use the same type of light sensor each time. We will get the same people to do the same tasks ever time to make this a fair test. My prediction was correct, this is shown in the averages; on the north side there is least light Evaluation: I think that the experiment worked out pretty well because from the averages I can see a pattern.

The averages were accurate enough but the separate results were not, this is because some of the trees that we tested for Pleurococcus we in a shaded area for example on trees 2,3 and 4 there is a lot of Pleurococcus on the east side because these trees were next to a fence that shaded them on the east side. To make this experiment more accurate I could have counted the amount of Pleurococcus in the individual squares in the quadrat, for example: I would have counted this as 4 out of 6 but if I had more time I would have counted it as 2.
