Sugars, which are formed by the plant during photosynthesis, are an essential component of plant nutrition. Like water, sugar (usually in the form of sucrose, though glucose is the original photosynthetic product) is carried throughout the parts of the plant by the vascular system. Phloem, the vascular tissue responsible for transporting organic nutrients around the plant body, carries dissolved sugars from the leaves (their site of production) or storage sites to other parts of the plant that require nutrients. Within the phloem, sugars travel from areas of high osmotic concentration and high water pressure, called sources, to regions of low osmotic concentration and low water pressure, called sinks. (Osmotic concentration refers the concentration of solutes, or sugars in this case; where the concentration of solutes is highest, so is the osmotic concentration).

Genetically modified (GM) foods are the ones came from organisms whose genetic material (DNA) are altered as they do not occur naturally. Food shortage, cost, variety can make people support the GM foods, while, religious beliefs, allergy, and worrying about the food can limit the support for these foods.

<h3>What are the characteristics of GM foods?</h3>

Genetically modified (GM) foods are those derived from organisms the ones genetic material (DNA) has been altered as they do not occur naturally.

Its characteristics are:

More nutritious food.
Less use of pesticides.
Faster growing plants and animals.
Disease- and drought-resistant plants.

As food shortage, cost, variety can make people support the GM foods, while, religious beliefs, allergy, and worrying about the food can limit the support for these foods.

Thus, the correct option is A.
