It takes ALOT of sunflowers. For example, a pound of oilseed produces just under three ounces of sunflower oil. Therefore, it will take almost 3 pounds of sunflower seed to make 1 cup of sunflower oil.
Sunflower oil is the non-volatile oil compressed from sunflower (Helianthus annuus) seeds. Sunflower oil is commonly used in food as a frying oil, and in cosmetic formulations as an emollient. Sunflower oil was first industrially produced in 1835 in the Russian Empire. The world's largest sunflower oil producers now are Ukraine and Russia.
Sunflower oil is a monounsaturated (MUFA)/polyunsaturated (PUFA) mixture of mostly oleic acid (omega-9)-linoleic acid (omega-6) group of oils. The oil content of the seed ranges from 22 to 36% (average, 28%): the kernel contains 45–55% oil. The expressed oil is of light amber color with a mild and pleasant flavor; refined oil is pale yellow. Refining losses are low and the oil has good keeping qualities with light tendency for flavor reversion. The oil contains appreciable quantities of vitamin E, sterols, squalene, and other aliphatic hydrocarbons, terpene and methyl ketones (chiefly methyl nonyl ketone).]citation needed[
Plant reproductive morphology is concerned with the physical form and structure (the morphology) of those parts of plants directly or indirectly concerned with sexual reproduction.
Among all living organisms, flowers, which are the reproductive structures of angiosperms, are the most varied physically and show a correspondingly great diversity in methods of reproduction. Plants that are not flowering plants (green algae, mosses, liverworts, hornworts, ferns and gymnosperms such as conifers) also have complex interplays between morphological adaptation and environmental factors in their sexual reproduction. The breeding system, or how the sperm from one plant fertilizes the ovum of another, depends on the reproductive morphology, and is the single most important determinant of the genetic structure of nonclonal plant populations. Christian Konrad Sprengel (1793) studied the reproduction of flowering plants and for the first time it was understood that the pollination process involved both biotic and abiotic interactions. Charles Darwin's theories of natural selection utilized this work to build his theory of evolution, which includes analysis of the coevolution of flowers and their insect pollinators.
Agriculture in Mesoamerica dates to the Archaic period of Mesoamerican chronology (8000-2000 BCE). During this period, many of the hunter gatherer micro-bands in the region began to cultivate wild plants. The cultivation of these plants probably started out as creating increased surplus and known areas of fall back, or starvation foods, near seasonal camps, that the band could rely on when hunting was bad, or when there was a drought. The plants could have been brought purposely, or by accident. The former could have been done by bringing a wild plant food closer to a camp site, or to a frequented area, so it was easier to get to or collect. The latter could have happened as certain plant seeds were eaten and not fully digested, causing these plants to grow wherever human habitation would take them. By creating these known areas of plant food, it would have been easier for the band to be in the right place, at the right time, to collect them.
As the Archaic period moved on, these cultivated plant foods became more and more important to the people of Mesoamerica. The reliability of the cultivated plant foods would allow the micro-bands to increase in size. These larger bands would require more food, and that would lead to even greater reliance on purposely-cultivated plant foods. Eventually, a subsistence pattern, based on plant cultivation, supplemented with small game hunting, became much more reliable, efficient, and generated a larger yield. As agriculture grew to become a larger part of the Mesoamerican diet, the people would have increasingly settled down in permanent villages and developed increased division of labor and social stratification as surplus grew.

A vegetable oil is a triglyceride extracted from a plant. Such oils have been part of human culture for millennia. The term "vegetable oil" can be narrowly defined as referring only to substances that are liquid at room temperature, or broadly defined without regard to a substance's state of matter at a given temperature. For this reason, vegetable oils that are solid at room temperature are sometimes called vegetable fats. Vegetable oils are composed of triglycerides, as contrasted with waxes which lack glycerin in their structure. Although many plant parts may yield oil, in commercial practice, oil is extracted primarily from seeds.
On food packaging, the term "vegetable oil" is often used in ingredients lists instead of specifying the exact plant being used. Seed
Perennial sunflower is a new crop being developed by crossing wild perennial and domestic annual sunflower species.
Annual sunflower is a major oilseed crop. Genes from wild perennial relatives may increase root depth and mass and extend the growing season. These upgrades means future varieties with higher yields and better soil conservation. Business Finance
Food is any substance consumed to provide nutritional support for the body. It is usually of plant or animal origin, and contains essential nutrients, such as carbohydrates, fats, proteins, vitamins, or minerals. The substance is ingested by an organism and assimilated by the organism's cells in an effort to produce energy, maintain life, or stimulate growth.
Historically, people secured food through two methods: hunting and gathering, and agriculture. Today, most of the food energy consumed by the world population is supplied by the food industry. Matter
