Plants require nitrogen because the element is a chief component of many of their structures and metabolic processes. Among other things, nitrogen is a critical ingredient in chlorophyll, the chemical that enables photosynthesis to occur. Nitrogen is one of the six primary macronutrients that plants need, and many gardeners use fertilizers to ensure that their plants have enough of it.Continue Reading
Nitrogen is a component of many plant structures, but it plays an especially important role in the structure of the roots. When the roots have adequate nitrogen, they perform more efficiently. This allows the plant to draw more water and other nutrients, and produce more growth. When plants do not have enough nitrogen, they languish and die. Small size, poor growth and yellow or red leaves are all symptoms of nitrogen deficiency. Too much nitrogen can also cause problems for plants. This does not happen very often in the natural world, but gardeners can cause nitrogen toxicity if they use too much fertilizer.
As it makes up the bulk of the Earth’s atmosphere, plants are surrounded by gaseous nitrogen. However, they cannot use it in this form; they must absorb it through their roots from a water-based solution in the soil.Learn more about Biology
According to ScienceDaily, biodiversity is the variety of species and genes of animals, microorganisms and plants found on Earth, including their connections and natural processes. Biodiversity is important because it provides biological resources, such as food and medicine, and ecosystem services, such as protection of water, soil, climate and nutrients. Biodiversity also absorbs pollution, promotes tourism, supports education and research and maintains the ecosystem.Full Answer >
Every living organism, animals and plants, need a continual supply of energy to perform the processes necessary for reproduction and survival. Some of the processes like metabolism occur continually, while others only occur at certain times, like muscle contractions and cellular movements.Full Answer >
In plants, the cellular structures involved in producing more cells are the nuclei, which divide in a process known as mitosis. These structures, considered to be the control centers of the cell, contain the genetic information of an organism.Full Answer >
The path of nitrogen through its biogeochemical cycle involves the path it travels from the atmosphere through fixation in soil, uptake in animals and eventual release back into the atmosphere. The nitrogen biogeochemical cycle is extremely important for life on earth because nitrogen is needed for all of the major biological molecules, including amino acids, DNA and RNA.Full Answer >
