Plants turn towards the light, but why?
The light is essential to green plants. It attractive the green chlorophyll, giving it energy for the process of photosynthesis, necessary for the life of the plant.
Each plant needs a certain amount of light.
The violet likes the shade, tropical plants need the sun, and the mallow adapts to any amount of light.
So, before deciding the position of a plant we need to know what it needs.
A violet in full sun will wither whereas the growth of any tropical plant in the shade will be stunted.
The direction of the light is also important. The plants which strain towards the light, or with long stems and small leaves are not getting enough light. Plants with stems which are too weak for their leaves have too much light.
The magic behind the attraction of the insects towards the flowers
The brilliant papery petals of the poppies and the sunflowers. The unusual beauty of the snapdragon. The heavy perfume of the jasmine. None of these are given by nature for the pleasure of the human beings. Instead, these are the magic gifts by the nature and the methods by which flowers attract insects.
Bees, flies, butterflies and all other little insects as the fly from flower to flower sucking the delicious nectar, so they carry the pollen by which a flower can reproduce.
Why are the insects important to plants?
The plants produce flowers which get the attraction of the insects. Landing on the flowers to suck the nectar, the insects become covered with pollen, a fine powder produced by the male organs of a plant.
And when they go on to another flower, the pollen is deposited on the female organs, fertilizing them and so beginning a new plant.
Not all plants need insects so that they can reproduce – but those which do have many different ways of attracting them.
Those attracting bees have yellow and blue flowers, because bees do not see the color red. Those visited by night butterflies have white, highly perfumed flowers which open only at night.
Plants have spent more than one hundred and fifty million years adapting themselves to the world in which we live. So, when man alters the natural balance and destroys a type of insects for their reproduction also disappear.
Flowering plants make up about 70 percent of the world’s plants, with 235,000 species worldwide. Almost all of our vegetarian food starts as flowering plants, and many of our meat sources are supplemented with flowering plant products. Benefits of insects to plants that directly and indirectly blossom all living things on earth.
The evolved relationship between flowers and insects – Mutualism
Mutualism is a symbiotic relationship in which both species benefit from exchanges. However, the relationship between plants and insects is likely to begin with plants is the most beneficial in the beginning. The emergence of a plant before its contact with insects is limited by the ability of plants to disperse genetic material by wind or water-borne pollen. Where most plant species have produced complete gametes. The scattering of grain at that time would not be as dangerous as pollinating the air. The pollinators have done this with the following limits, the level of the member receiving and the chance of success. Therefore, insects can act as a more direct carrier of genes and increase the efficiency and diversity of mixing with the gene pool of plants. So the function of the Plants was to produce a reward for the insects to collect for the purpose of visiting the flower and taking the load.
