why are minerals useful to plants?
80266
plants need minerals as their food through the process of photosynthesis as people need minerals, vitamins, carbohydrates, protein fats , oil, etc as food through the process of digestion and assimilation

Rain water is good for plants. Put a barrel or bucket out to capture rain water, add a bit of bagged manure from the garden section,let it sit and use that water for your plants. They will grow spectacularly :)\nTap water has been treated and lost all of it's natural minerals.\nWell water is a very good water source also as it has all it's natural minerals.

hardness, luster, clevage, composition, crystal structure\n\niron is useful also in the mineral gypsum they use it to make drywall\n\nmost gems are valueable because they form extremely slow making them rare, they are also the very hardest type of mineral

The leaves of a plant play an important role in the plant. The leaves capture sunlight and use it along with carbon dioxide to produce food for the plant. Tthe process gives off oxygen. The leaves also store the food for future uses. The leaves have stomata for the escape of the not needed oxygen.

Plants are the true essence of life. Without them, no life in this world could be possible. When life appeared on earth, plants were the first to appear and then changed carbon-dioxide to oxygen and thus made life possible on earth. Even economically they provide us with lots of products. They control the climate on earth. So, with so many utilities they really are the most important thing on earth. So we must study their structures properly because that will help us sustain them on earth and in that way sustain ourselves too.

wow at first i thought you meant how are insects useful to plants that eat them... but i guess you mean insects as a general usefullness to plants... its probably too broad to answer correctly...  but commonly they help disperse pollen, as with bees... or when they eat the fruit and defecate the seeds elsewhere... and insects also can eat other insects tht prey on the plant... they also trim and pare the plant naturally... and lastly they keep it company... plants cant move and really can get quite lonely sometimes...

Minerals such as calcium, phosphorus, and magnesium.

In order for a plant to grow and thrive, it needs a number of different chemical elements.\nThe most important of these (the ones that are needed in the largest quantity by a plant) are nitrogen, phosphorus and potassium. \nWithout nitrogen, phosphorus and potassium, the plant simply cannot grow because it cannot make the pieces it needs\nTo make plants grow faster, what you need to do is supply the elements that the plants need in readily available forms. That is the goal of fertilizer. Most fertilizers supply just nitrogen, phosphorus and potassium because the other chemicals are needed in much lower quantities and are generally available in most soils. Nitrogen, phosphorus and potassium availability is the big limit to growth. \n\nAre you aware that plants need at least sixteen elements for healthy growth and that only four of them are commonly applied as fertilizer? These four are calcium, phosphorus, nitrogen and potassium. \n\nThe numbers on a bag of fertilizer tell you the percentages of available nitrogen, phosphorus and potassium found in the bag. So 12-8-10 fertilizer has 12-percent nitrogen, 8-percent phosphorous and 10-percent potassium. In a 100-pound bag, therefore, 12 pounds is nitrogen, 8 pounds is phosphorous and 10 pounds is potassium. The other 70 pounds is known as ballast and has no value to the plants. \n\nThere are many forms of fertilizers, and from my vast experience in growing shrubs, plants and garden crops I have not found a particular advantage of using the liquid over the dry: it is perhaps a matter of personal preference. The dry forms of fertilizer seem to work best on starter plants and are also excellent for accurate application to houseplants and other container grown plants.

plants use the sunlight to turn nutrients into sugars to feed the plant they also take the toxins away from the plant when they go brown and drop off. Carbon dioxide and oxygen are released from them.

Many parts of plants are used to make medicines.  It's usually because that plant evolved to deal with disease or hazardous conditions.

Because it has nitrogen and nitrogen is essential in plants' life.

They provide oxygen.\nThey make the soil fertile by the process known as rhizo-deposition.\nThey trap energy from sunlight, which could have otherwise heated up the planet.

Depending on the plant...most plants in general need H2O (water), Co2 (carbondyoxide), and sunlight.  They say talking to a plant helps because of t he CO2 we give off.

Try this website, it has some good explanations of things like total dissolved solids, dissolved carbonates, boron, and other things often found in water used for growing plants. There's even a little information that is specific to grasses. \nhttp://www.ext.nodak.edu/extpubs/ageng/irrigate/eb66w.htm#plants\n\nBy the way, I found this using the search terms:\nirrigation water\nSo if you want to duplicate my search and see other results this should get you going.

Nitrogen Phosphorus and Potassium remember NPK These elements are always essential to a plant and it's roots

by nitrogen fixation they convert unusable N2 to NH4+ (ammonium) so plants may use it for food

well without it their cells would shrivel up and die...\n\nwater is essential to dissolve most minerals and compounds in because it is a polar molecule and things are easily dissolved in it. the body takes advantage of these properties of water and our living system is based off of the properties of water and most of our bodies are actually made up of water.
