Your observation that moss just grows top top thenorth side of trees tells me girlfriend haven"t lookedfor moss near trees in the southern hemisphere. Moss is a simple plant and likes to flourish inshady locations so it does no dry out.
You are watching: Why does moss grow on the north side
It ispretty an easy to snapshot why this is the northside of tree here and the south side of tree inAustralia because that example. The sun"s light ray strike theearth"s surface almost perpendicular close to theequator.
together you relocate away from the tropics, the sunsrays intersect the planet at an angle. Right here inSanta Barbara, California, the sunlight is not directlyoverhead, yet to the south, so the south side ofany object will get an ext sunlight than the north. This is why moss likes the north side of trees.
The fuzzy texture and also shade-lovingcharacteristics that moss space in part due to itbeing a non-vascular plant.Mosses belong to a group of tree calledBryophytes. this plants execute not haveroots, or the xylem and also phloem that vascular plants,but rather have rhizomes that organize the moss inplace and also collect water and also nutrients the mossrequires.
The "fuzzy" structure you mention helps to keepthe tree from drying out and also helps diffusethe light offered for photosynthesis.Answer 2:
Good question! Actually, moss doesn"t onlygrow top top the north next of trees,it just MOSTLYgrows on the north side. Also, that ruleonly uses in the north hemisphere--inthe southerly hemisphere, moss largely grows on thesouth sides of trees. The factor is the in thenorthern hemisphere, since of the tilt of theEarth top top its axis, the sun nearly always appearsto be a small south of directly overhead. That"swhy rooms with windows encountering south are brighterthan rooms through windows encountering north. This isimportant for the mosses due to the fact that the phibìc sidesof tree (in the north hemisphere)are shadierand because of this moister. The southern sides of treesget more sunlight, for this reason water evaporates fasterthere.
Mosses require a lot of water because that tworeasons. One is that they"re not"vascular"plants --that method that castle don"t have actually theplant version of a circulatory system, and also theycan"t relocate water around inside their bodies. Allcells in a moss"s body require to have actually easy access towater from the environment.
The 2nd reason they require water is becausetheir masculine reproductive cells deserve to only survive byswimming in droplets the water. Theonly means these cell can get from one plant toanother is come hope that a raindrop will reason thewater they"re swim in to it is in splashed ~ above aneighboring plant. If the surface that castle liveon (like a tree trunk)dries out, the moss will certainly beunable to reproduce, and it will dry out. That"smuch more likely to take place on the sunnier next ofa tree trunk than on the shadier side.
The very same rule uses to rocks, collapse logs, oranything else the mosses can grown on. If ithas a sunny side and a shady side, the mosswill mostly thrive on the shady side. In thenorthern hemisphere, that"s usually the northernside, and in the southerly hemisphere, it"s usuallythe southerly side. If friend look very closely enough,though, you"ll check out exceptions.

The structure of mosses is generally (but notalways!) fuzzy since their leaves have actually manylittle projections ~ above them, favor the finger-likeprojections ~ above a maple leaf. The moss leaves andtheir projections space so small, though, the theyseem fuzzy to us. This projections space probablyto help the moss cell deep within the pipeline tobe together close as feasible to outside water sources.
