Plants around us

INTRODUCTION

The choice of plants in the task has been in the area where I live. The surrounding area has Delsjö reserve with lots of different species. Some species I have picked in our garden.

The species has been divided into two main groups, phanerogams and cryptogams.
Seed plants, ie. fanerogamerna has in turn been divided into four groups:
Herbs, rice, grass and trees
Sporväxterna, fanerogamerna has also been divided into four groups:
Mushrooms, clubmoss / horsetail / ferns, lichens and moss

Among the fungi that I have picked is most edible, but some, such as toadstool or puffball is inedible unless they are cooked properly. Some flowers such as white clover is also inedible.

Although all the species that I have picked is not edible or has some direct benefit to humans, so they are included in the ecosystem and contribute anyway for the benefit of humanity. Plants, animals, etc. in nature cooperate and are interdependent in any way. On the news today they said, among other things. alia, that the Gudrun storm, which made an enormous number of trees felled, had its effect on the concentration of mercury in fish. It was due to the fact that in some areas the vegetation changed to take care of emissions and pollution. Moss Orna addressing metals could not grow so that the mercury flowed into the lakes and was taken up by the fish instead.

We humans live by nature and the products of it. Sometimes we make about the products and may, for example, medicine, food, etc., and sometimes we can only use what nature provides, fruits, berries, vegetables and more. We also get fuel, as oil and gas from both plants and from drilled holes. From forest and quarry we get building materials from plants, dyes, vitamins, etc..

The plants need water, carbon dioxide and sunlight, they contribute through their synthesis to oxygen production. Is usually called the rainforests of the world's lungs, and once they have been harvested and reduced in size so enormously during these last fifty years, so this may impact on the whole environment. 1940 covered them 14 percent of the Earth's surface and today covers them only 6 percent! Coral reefs in the oceans is usually called the ocean's rainforests thanks to its diverse life. One of the world's most productive biological systems. Thousands of species live in a very complex ecological interactions. The climate has changed very much. There have been floods, severe storms, earthquakes, etc. and this may be due to the conditions of nature has changed. We must protect our nature and our diversity because we need it.

Biodiversity is the variability within species, between species and of ecosystems in the landscape. Diversity gives us everything from food and clothing to medicine and housing.
Biodiversity is usually divided into three levels:
diversity of species (the amount and variety of all the different animals and plants in the area)
diversity of ecosystems (all species in a defined area)
genetic variation within groups. (That there are variations of a species, eg dogs. If there is variation, it can lead to inbreeding that can lead to birth defects, among others. A.)
For the last fifty years, economic and technological developments helped improve the survival of a large portion of the world's population. But this has also affected biodiversity so much that ecosystem's ability to make progress now threatened in the past. There is a direct link between biodiversity and ecosystem's ability to deliver food, medicine, energy, etc. to man. What once damaged or destroyed is much harder to correct again. That is why it is so important that people take responsibility in nature, before it became too late. There will be future generations who will suffer for our mistakes and our carelessness.

Seed plants, fanerogamerna, judgment flowering plants reproduce by seeds and is like so much else in nature is a part of a whole. Wind flowers that need the help of the wind to blow away large amounts of pollen. Insect flowers cooperating with the insects. Pollen and nectar that sticks to the insect and carried to the next flower to be pollinated. Meanwhile, the insect nutrition and growing. It may in turn become food for a bird which in turn become food for a fox. The bird might have eaten cherry or similar may add their droppings in a place where a new tree may grow. Fox keeps before it might fall prey to a hunter's bullet, a balance in nature with deer and hares so they will not be too many in a certain area.

Dom non-flowering plants, cryptogams reproduce by spores. You may think most of fungi when talking about spores. Fungal spores varies from white to black and spread in different ways. Röksvampens dissemination is done through an "explosion" and the spores blowing away like a puff of smoke. Of the fungi, we also, in addition to food medicines eg. penicillin. The fungi have no chlorophyll, they suck their nutrients directly from the environment. Moss Orna who is also kryptogama, has no roots and take their nourishment directly from precipitation and air. This makes them react quickly to air pollution. Moss Orna live many times in a life together with lichens. The fungus needs "ready" food, which it gets from the lichen. Lavenders need nutrient and water, which it gets by the fungus.
There are many organisms that live a similar life together for mutual benefit. Other organisms, eg microorganisms are very useful due to its ability to break down pollutants in the air and soil. It may be things you do not think about very often but still have a significant impact on our environment.

In nature there the entire time this cooperation and requirements between species, plants, animals and humans. Biodiversity on Earth is the result of about four billion years of evolution. Some species have disappeared, others have arisen. Sometimes, humans have bred or altered in any other way. This applies to both plants and animals. Biodiversity and the interaction of different types of ecosystems is essential for human life. Forests, coastlines, rivers, groundwater're all important for life. If we destroy beaches and coastal scenery disappears spawning grounds for many fish. When forests are devastated so also changes the water balance. Now, the knowledge of this increased and nowadays is never completely cut down clearcuts. It is always left some trees and the like to preserve the lives of others to live on, for example, insects, woodpeckers, etc. It has also begun to work the land with more nature-friendly practices.

We who may not be working in and with nature can still help to improve the environment.
We can refrain from buying products from tropical rainforest areas. One can choose to buy organic foods. Then we know that is not so much pesticides used. Money collected to organizations that care about the rainforest areas. We ourselves can avoid chemical pesticides. Failing to buy pets that are bred in captivity and are not wild caught or perhaps smuggled. If we buy goods from the resort so we know that it has become shorter transport distances and not so much the emissions and air pollution.

I have learned that cooperation between species, as they do not think about every day, is very important for our environment, the future and our ability to maintain a beautiful world for future generations. It's also we humans are responsible for much of the cooperation, not least environmental degradation ...

In the woods, I've learned that I can find blood Islands during firs. I recognize various mosses and lichens, and I know they are sensitive to air pollution when they're taking a lot of their nutritional airway. I have also learned that many plants are very beneficial to humans. We get food, vitamins, medicines, fuel, etc.. The plants also helps with oxygen production, taking up environmental toxins, give us building materials and more. I have also learned that some plants are very sensitive to environmental changes, while others are very resistant. But the main thing I learned is that we were afraid and cautious about our nature.

    In the preamble it says that both spore plants and seed plants are phanerogams!
