Why do plants need an sunlight to survive?

Why do plants need an sunlight to survive?  Below are some amazing news and facts about this.

Plants need light to grow so that the process of photosynthesis can occur. This process, found only in plants, converts solar energy into sustenance for plants. A substance found in plants known as chlorophyll converts light into carbohydrates, which becomes food for the plant. That might be one of the most awesome random facts ever.

A plant kept in a place where there is no light or sun whatsoever withers and dies. A plant must have some sort of light or sun in order to grow. A plant also requires water and warmth to germinate and grow. Some plants do need more or less light than others in order to grow properly. There are typically instructions on a plant that a gardener should read prior to planting. Some different levels of sunlight include deep or dense shade, partial shade, light shade, part sun and full sun. Learn more about amazing science facts via our articles.

Some plants burn if planted in complete sunlight, and all they require is a shaded area in order to prosper. If the colors of a plant are washed out and it is dry, it is most likely receiving too much sun. If growth is sparse and the plant seems to be leaning toward a light source, it needs more sunlight. Fluorescent grow lights are also an option for those that cannot place a plant outdoors. The process of photosynthesis is still able to occur under this type of light.

Moss can't grow high?

Moss can't grow high? Is it true? See to know

Here is a photo demonstration of the height difference between mosses and other plants such as trees. The mosses are in the foreground mixed in amongst the grass. They measure in at about 6 centimeters or so tall. Whereas the trees in the background are over 10 meters (1,000cm) tall. {Dig back for your scientific conversions if you have not used them in a while. There are 100 centimeters in a meter, so the decimal is moved two places to the right to convert from meters to centimeters}. Check out my list of fun, weird and just plain amazing fact of life I have found.

So what is the cause of this extreme difference in height?

The answer is Water. Water is one of the required elements for plants to carry out photosynthesis and live. Plants such as trees absorb water through their root systems and then transport the water to their leaves, the site of photosynthesis, through conducting cells. The cells that move water from the roots to the leaves are called xylem cells. These cells are dead at maturity and are very tough. They are the type of plant cell that composes wood. The substance that adds to the strength of these cells and makes them retain water to function as internal plant piping is a compound called lignin. That might be one of the most awesome random facts ever.

Mosses however do not have lignin in any of their cell walls and they do not have xylem cells either. Thus mosses do not have an efficient system for transporting water within their body long distances. Mosses absorb all of their water from the outside environment directly through their leaves and stem. (Imagine drinking through your skin.) Most plants must be small in order to keep their entire body hydrated and thus are limited in the height to which they can grow while still maintaining wet leaves. Also without the strength that xylem cells provide a very tall moss would be super flimsy. It would be like trying to build a tree out of wet spaghetti noodles. Quite the difficult task. Mosses have thus maintained a small stature for millions of years and despite the time have not gotten any taller.
