Plants are important to us bc they provide the air we need to breathe, we can use them as herbs for healing injuries or health (some are used in medication), we use them for our skin like when its in dermatalogy products & whatnot, & not to mention they are great for making tea & pretty to have around.

Botany is the scientific study of plants and their environment.  It includes genetics, biochemistry, physiology, anatomy at a gross (large) level as well as at a tissue and cellular level (microscopic) and includes intracellular things such as chloroplasts and other specialised cell contents.  \n\nBotany also deals with plants in their environment e.g. soils and the nutrients derived from the soil (minerals etc).  Other aspects of plant growth and development are important in relation to light, temperature, water, humidity, salinity etc.\n\nBotany may also include plant pests and diseases and the problems of poor soils.  In addition, adaptations to specific conditions e.g. salt, drought are covered.  Plants are useful to medicine as many medicinal chemicals are derived from plant leaves and other parts; likewise there are many poisons that are plant-based (e.g. some fungi).\n\nThe relationship between plants and animals e.g. for fertilisation (birds, bats, insects) and seed dispersal (birds, mammals) can be involved in botany too.\nInteresting subject!

With the increase in the human population agriculture is going to become more important than ever.\n\nMost crops are being grown on large estates to get the benefit of economies of scale. \n\nThe chemical boosting of agriculture seems to be coming to an end. Farmers are putting fertilisers, weedkillers and plant killers on their crops with diminishing returns.\n\nThere is a move back to sustainable agriculture which means that farmers tend the soil with compost and let fields lie fallow and use less chemicals on the land.\n\nOrganic farming is also making inroads into the mass commercial production of crops - that is farmers who grow crops without using any chemicals.\n\nGenetically modified crops should improve yields and profitability  once the issues over the release of the plants are resolved.

Bacteria is essential in the breakdown of matter.  Ecologically, bacteria breaks plant and animal matter down into nutritious soil for new plants to grow.\n\nEconomically? Compost, antibiotics, yogurt, etc. all need bacteria.  Also, if bacteria didn't help break down matter, we would have to pay to get rid of it.

Pardon me if I am incorrect but i dont think that plants NEED more energy rather they HAVE more energy. Each time you move up the food chain, only 10% (?) of the original energy the organism had is retained. The rest is lost. Since plants are at the bottom of the food chaing and are autotrophs, they receive 100% of the energy they converted through photosynthesis. Then the rabbit who eats the plant gets only 10% of that and the fox who eats the rabbit gets only 1%.

Try to think of all the things that plants use potassium for. Potassium is extreemly important for animals - for a start it regulates our heart beat. For plants one of its major uses is to control the opening and closing of stomata, this affects the rate at which water evaporates from the leaves. Plants also use it during photosynthesis and respiration (the P in NADP etc.), so it's pretty essential. Plants can germinate without an external source of it because they generally have some in their seeds, but it will not grow or die without potassium.

Medicinal Plants \n\nPlants have been used as healers and health rejuvenators since time immemorial. Even now, WHO recognizes that medicinal plants plays an important role in the health care of about 80 percent of World population in developing countries and depend largely on traditional medicines, of which herbal medicines constitutes the most prominent part (Fransworth et al. 1985). The rest of the 20 percent also depend substantially on the plant-based medicines. \n\nAmong the rich and varied plants of Indian forests the medicinal plants constitute an important source, the use of which for human and veterinary health care has probably continued, in an unbroken tradition for well over 2 millenium. \n\nMany people have defined medicinal plants in many ways, out of which the accepted definition given by the Agricultural and Natural Resource Development is, \n\n            “ Plants that are recognized by people to have reliable and effective medicinal values, are commonly used in treating and preventing specific ailments and diseases, and play an essential role in health care.” \n\nThe number of medicinal plants in India, both indigenous and introduced has been estimated to be between 3,000 to 3,500 species of higher plants. The Glossary of Indian Medicinal Plants has listed around 3,000 plants (Asolkar et al., 1992; Chopra et al., 1956, 1974). Two thousand five hundred plants have been reported to be used in ethno-medicine (Jain, 1991). The number of plants listed in Ayurvedic Materia Nighantu is 560 in Bhav Prakash Nighantu (Kumar 2000). The Ayurvedic Drug Formulary prepared by Department of Indian System of Medicine, lists 387 plants (Sarin, 1996). The Unani system of medicine describes 440 plants (Said, 1969) out of which 360 are common to other systems practiced in the country. The number of plants having confirmed therapeutic properties or yielding a clinically useful chemical compound thus lies around 700 species. The occurrence of these medicinal plants and availability of raw materials from them is as follows: \n\n•  Plants occurring wild in forests, grasslands, aquatic and desert ecosystems, associated with other forms of natural vegetation. \n\n•  Plants growing as weed. \n\n•  Plants cultivated as ornamentals or as cereal, fruit, vegetable, spice, oil seed, essential oil or other cash crop. \n\n•  Plants cultivated as medicinal crop. \n\nIn addition, almost 25% of the entire compounds of current prescription drugs were derived originally from plant sources (Balandrin et al, 1985). Of the estimated 25,000 flowering plant species in the world today, only about 10% have been scientifically examined for their medical application, mostly in rudimentary way. Undoubtedly, many more plant-derived medicinal substances await discovery (Akerale et al. 1991). The information on the medical wealth of these examined 10% of plant species is scattered in different sources. \n\nThe Western Ghats is very rich in its medicinal wealth. The forests and hills of this region   is a treasure house of about 700 medicinal plants. Out of which some are used for traditional and folk medicinal practices. Many are exploited commercially for their active enzymes and their commercial value. \n\nMedicinal plant species of Western Ghats represent a variety of life form ranging from lichen, algae, herbs, shrubs, climber and trees, which are annuals to perennials. Moreover these species are distributed from canopy to understorey and are characterized seasonally. The auto-ecology and syn-ecology of medicinal plant species is complex and their proper understanding requires a sound knowledge of the ecology, taxonomy and ethno-botany for these species. Western Ghats with its species diversity is a treasure house of different kinds medicinal plants. \n\nThe limited knowledge on the varied use of the medicinal plants, their availability and extent of distribution weakens the ways to utilize these resources efficiently. Therefore, it is required

First, I am not a scientist but a scientfic researcher. It's important to know what animals eat the seeds or fruits of flowering trees to deduce it's role in a given ecosystem. It's relationship to the other living organisms in it's environment is very important. It's also imortant to know what animals very existence hinges on the trees continued existence in the ecosytem. In other words, as trees get chopped down and various animal species that depend on the trees start to die, that is then a useful barometer of the trees role in the ecosystem.

Most life on Earth is powered by the Sun. Plants use Photosynthesis to make carbohydrates from the Sun. Animals eat Plants, we eat both plants and animals that eat plants. Therefore indirectly virtually all of our food energy comes from the Sun. Our Brain uses our food energy to operate. Therefore our brain is powered by the Sun.

Water and "nutrients" depending on the specific type of cell. Plant cells need inorganic nitrogen compounds (ammonia, nitrate), phosphate, iron, magnesium, manganese, copper,...\nAnimal cells need organic substances like sugars or amino acids (which plant cells can produce on their own) additionally to vitamins and ions (iron, copper, cobalt, zinc, molybdenum, iodine, selenium,...)

aaah plants are soooooo boring. I hate plants.  I'd wait for human genetics rather than being bored out of my miiiind with plants.

Usually, plants take nutrients from the soil and air and use it for fuel for their growth. Animals tap into this cycle by eating plants during this process. A plant species doesn't want to die, so it adapts to make itself harder to eat (thorny, poisonous, hard bark, etc.) and maybe also to take advantage of animal behavior to propogate itself (fruits, nuts, etc.). Animals who can't get easy plant food any more need to adapt too (resistance to poison), and may begin working with the plant to propogate their food source in return for an easy and sometimes exclusive snack or shelter (hummingbirds, etc.). Rarely, plants adapt to the presence of animal food as a booster source of nutrients, especially in nutrient-poor soil (venus fly traps, etc.). Sometimes, plants and animals come to work in such close cooperation that neither would easily survive without the other (honeybees and flowers).\n\nAdaption and evolution is the best way to describe the interactions between plants and animals in a systematic sense.

Nature and nuture are both important factors to who and what you become.  Your surroundings(nature) are important aspect because it is the thing you see everyday, its the place that you will consider the norm. Nuture is also important because its where you develop some of your characteristics, for some its where you begin to show your personaility, traits, strengths, and weakness.  Some people also argue that its the enviroment that truely affects and shapes you, because some people lacked the nuturing factor in life or vice versa.  For everyone its different but in most cases people will agree there is to some degree a mix of both nature and nuture.

plants consist of cells lik anmals have.the difference is plants contain chloroplast to make their own food and animals dont have chloroplast but plants do contain mitochondria lik anmal cells and thus keep utilising the food  by respiration that they  had made during photosynthesis.if they dont  bring about resperation that is utilisation of the food they make thy will die hence plants carry out photosynthesis and respiration tooo
