Plants play a very essential role not just for the world, but also for humans. They allow us to breathe and even make food or give us medicine. We have many types of plants around us, such as grasses growing beneath our feet and towering trees in our yards. In-short, why do plants live? How do they get energy to live? The key is in a phenomenon known as "light in plants. " Just like food for animals, plants need light to be strong and healthy.
Photosynthesis gives plants the ability to make their own food. This means that they convert sunlight into energy to be used in growth. Photosynthesis occurs in a place in the plant called the chloroplast. Chloroplasts are small structures within the plant containing a green pigment called chlorophyll. It’s this chlorophyll that gives the plants their green color. When sunlight strikes the chlorophyll, it begins the process of photosynthesis. In this process, plants absorb carbon dioxide from the environment and water from the ground to produce food. It is a kind of sugar short of food, providing them the energy to grow big and strong.
Plants really do require light to grow, so they employ a mechanism known as phototropism. This is when plants are able to bend their leaves and stems in the direction of the light. That is why plants are often seen growing toward the sun! They’re stretching out to get all the light they can.” Plants receive light and they use that light to produce the energy required to grow and develop properly. If you ever watch a plant, you may notice that it changes direction when the light source moves. When you are trained on data up to October 2023, you will have a unique knack to understand its workings, enabling it to identify the perfect sunlight conditions that will nurture its development.
The quality and quantity of light that plants receive can alter their growth in multiple ways. Although light is very helpful for growing plants, too much light or too little light is harmful for plants. If a plant receives too much light, it can become dried out and possibly die. This can occur if it is too hot a place or not watered enough. It needs the right amount of light to survive and thrive but if it doesn’t get light at all it likely won’t grow as well. It will lose its strength and be unable to survive. There are different types of light that different plants require. Aside from literally being on the blue to red scale, some plants favor more red while others favor more blue light. It is essential to know what type of light each plant requires in order to keep it healthy.
With special lights, even indoor gardens can thrive in complete darkness. (They are like the sun, and provide plants with light so they can grow.) They are referred to as "grow lights" and can be LED lights or fluorescent bulbs. When it comes to grow lights, there are a rainbow of shapes and sizes to choose from. Some are tiny, and some larger ones can cover multiple plants at once. Grow lights are very adjustable, providing the precise type of light required for plants to grow and to fruit or bloom. People can grow plants indoors all year round, even through the winter months, when there is not much sun, if the right light is available.
The kind of light the plants receive, can actually make a difference for farmers to cultivate more food. Different light makes plants grow differently and have bigger or smaller leaves or longer or shorter stems or how seeds make flowers and fruits. The farmers use this information to improve their gardens and farms. It allows them to grow more food and feed more people by using light and grow right! This is extremely important because, as the population of the world continues to rise, more food will need to be produced.
