There is a clear winner of the Corona-lock downs. One of the Gold polypody is in my office. The garden experts on the Internet rates, this fern in love with a subtropical humid climate, I eagerly poured my protege on a daily basis. For the Plant must have the native rain more like Waterboarding felt: Since my colleague, it only sporadically poured, he is healthy as ever, his long, blue-green leaves Shine strong, and instead of a series of ways to die, and new ones grown. One of them is not a shallow-curled as the other, but of kraus, as you would have missed him a standing wave. While I think the roundish leaves of the Ficus in the neighbouring pot, I wonder, why leaves are shaped so differently?

a botanist in a particular language have grown to categorize leaf shapes, with terms such as "paired-pinnate", "fußförmig" or "obovate". The Gold polypody falls into the group of "linear". The Form depends, of course, with the function of leaves are to a certain extent, the vital organs of the Plant. Who remembers biology class, white, in the green chloroplasts photosynthesis takes place, from the energy of sunlight, water and carbon dioxide oxygen and glucose are.
water, sun, and hundreds of millions of years of Evolution
thirst shaping the Plant. Robust succulents, agaves, for example, have fleshy leaves in which water can save. A layer of wax protects it from drying out. If you want to survive in the desert, and must keep the house. It is quite different in the rain forest Where it rains constantly, you can use sheets to protrude also a basketball player, around the famous 2.5-Meter-long leaf of a sea grape tree that was found at the beginning of the eighties in the Amazon area. Here are the outgrowths of the Plant are rather thin and round, with a peak so that the water can drain well. The sun light affects the Growth of leaves, which are more likely to grow on shaded soil tends to be larger, more radiation capture, as such, is in a sun-drenched treetops.
In our latitudes, the leaves grow every year, with the exotic giants, you can't keep up. Their edges are often jagged, as in the case of the beech, and the leaf veins are often strong, a chestnut leaf can be the same as the bus schedule of a city. The leaves are specialized to grow as effectively as possible, says Klaus Minol. The biologist, the head of the Department Pflanzenforschung.de a project of the Federal Ministry of the interior. Him I'll call after I've found neither in studies of plant genetics – such as those in the journal "Cell" on the Gene LMI1, the hairy foam herb owes its pinnate leaves – still in the book "Ask times but the mouse – our forest," clear answers, why do leaves grow under the same conditions of life very differently. "Climate, competition, defense, and Evolution," summed Minol. "But why would the plants on a meadow of Flowers, all different sheets, you can tell exactly no one." Dandelion, birch and co. have hundreds of millions of years of Evolution behind. "The plants have their own Gen-sets." Presumably, the curly leaf in my office plant is just a freak of nature. I remain curious, which works of architectural art of the fern is still raising.Updated Date: 20 June 2020, 13:20
