Did you know that plants are living things? This is because plants feed by making foods from their leaves through the photosynthesis process. They also grow just like any other living things. Plants also carry out gaseous exchange through their roots and leaves and so forth. Plants include trees, shrubs, grass, ferns as well as mosses. Now that we know that plants are living organisms and therefore require care just like any other living organisms, we proceed to look at how man can benefit from these plants. There are as many benefits as you may think of and so we may not exhaust all of them. We can therefore say that plants are the backbone for all living organisms to survive.
Plants as food sources: The most immediate benefit that man gets from plants if food. Not only are plants sources of food for man but also other living organisms which feed on plants such as livestock which feeds on grass, giraffes that feed on twigs of trees among others. We therefore rely on food sources directly or indirectly from plants. Research shows that over 7000 plant species are used as food sources by man. How many have you used? Plants help us complete a balanced diet because they provide carbohydrates, vitamins, minerals, fats as well as proteins and therefore a vegetarian has nothing to lose since he or she can get all the nutrients from plants.
Medicine sources: The practice of herbal medicine is such an old practice and still continues to deepen its roots in most societies today. This is due to the fact that herbal medicines are safe to a greater extent by the fact that they are provided by nature though the manufacturing process may make them unsafe in some cases.
Plants and climate: Plants are very good when it comes to the control of global warming. We know that plants need carbon dioxide for their food making process and in return give us the oxygen, a by-product of photosynthesis, which we need to survive by carrying out metabolism for energy release. This therefore helps balance the amount of gaseous composition in the air by absorbing excess carbon dioxide. Too much carbon dioxide can be a threat to our environment since it destroys the O zone layer leading to global warming effects.
Sustaining life: Plants act as habitats for various organisms. Trees give man timber for house construction thus enable them get descent shelters unlike in the old days where man lived in caves before evolution. Moreover, they provide man with fire sources to cook and keep warm. Moreover, plants play a great role in the water cycle. They absorb water from the soil and release it to the atmosphere by transpiration process and this contributes to rain formation cycle.
Plants and beauty: Plants are also used to enhance the environmental beauty. It is common to find flowers and shrubs planted around most homes as fences and hedges to act as landmark as well as increase the beauty of the compound. If you want to see how beautiful your home can be, you can try the English Laurel.
How do plants survive?
It is possible that you wonder how some plants grow in areas even where there is no water yet they need this for photosynthesis. Others grow in too much water without getting poisoned by it. Well, plants have unique features that adapt them to whatever environment they grow in. This means that they can only grow in that environment and may never grow if taken to other conditions. For example, have you ever wondered why pants in the desert have small leaves? The cactus for example has small leaves to adapt it to the desert conditions where there is little or no water and this will therefore reduce the rate of transpiration. On the other side, those growing on the areas with plenty of water will tend to have larger leaves in order to increase the surface area for transpiration so as to lose excess water and avoid the poisoning effects. There are other features in the roots and stems that adapt plants to their living conditions.
