Sunlight and water both support the production of chemical nutrients inside the cells of a plant. Sunlight is critical in the process during which water molecules are broken apart inside the pigmented cells of the plant. Water also transports the nutrients throughout the plant and supports its structure.
This dependency on light to transfer electrons during photosynthesis, also known as Hill Reaction, remains mysterious to scientists. What is known is that during the reaction between the plant's cells and the sun's light, water molecules are broken apart, creating energy in the form of chemical food for the plant, as well as expelling extra "ionized" hydrogen atoms as waste in the form of the very oxygen that supports all life on earth. This makes the importance of water to a plant's life quite clear. Without it the plant would not be able to produce the food it needs to survive.
Plants need water for more than just food production, however. It is also needed to transport nutrients throughout all the plant's cells, from the roots to the leaves, for example. By keeping the plant's cells full and rigid, water also plays a critical role in supporting the physical integrity of a plant.
Water and sunlight are not the only ingredients that plants need to produce food. In addition to light and moisture, plants need carbon dioxide from the air, which is converted into sugars in a process known as the Calvin Cycle.Learn More
There are many plants in the Gobi Desert, including the saxaul. This is a small tree or shrub that keeps moisture behind its bark, making it an ideal survivor in the desert climate. Saxauls also feature an extensive root system that is capable of reducing soil erosion.Full Answer >
The process of gaseous exchange in plants happens in the leaves. Oxygen and water vapor leave the plant while carbon dioxide enters through pores called stomata. Plants require carbon dioxide for photosynthesis and oxygen for respiration.Full Answer >
Plants can survive without sunlight as long as they have another source of light in the appropriate spectrum, such as an artificial grow light. Plants can only survive in complete darkness for a finite period of time. Generally, plants that are in vegetative phases thrive on blue lights, while plants in flowering phases thrive on red and orange lights.Full Answer >
The life cycle of a Venus flytrap lasts up to 20 years. The plant takes six years to reach maturity, at which point it becomes a perennial plant. This means the plant blooms every year until the end of its life cycle.Full Answer >
