In vascular plants, the root is the organ of a plant body that typically lies below the surface of the soil (compare with stem). However, this is not always the case, since a root can also be aerial (that is, growing above the ground) or aerating (that is, growing up above the ground or especially above water). On the other hand, a stem normally occurring below ground is not exceptional either (see rhizome). So, it is better to define root as a part of a plant body that bears no leaves, and therefore also lacks nodes. There are also important internal structural differences between stems and roots. The two major functions of roots are 1.) absorption of water and inorganic nutrients and 2.) anchoring the plant body to the ground. Roots also function in cytokinin synthesis, which supplies some of the shoot's needs. They often function in storage of food. The roots of most vascular plant species enter into symbiosis with certain fungi to form mycorrhizas, and a large range of other organisms including bacteria also closely associate with roots.

This root crop is already known all over the world, thanks to the South Americans who cultured and grown this food wonder now taking rage in all places. The popularity of this wonder plant caught the attention of many most especially the naturalists who profess to the preservation of environment and related issues that conform to the natural well b

Hydroponics is the technique of growing plants without soil. The roots grow either in air, which is kept very humid; in water, which is well aerated; or in some solid, non-soil medium, which is kept moist. The water around the roots contains a carefully balanced mixture of nutrients that provides food for the plant.

Early man realized that cooking food make poisonous roots and plants edible, tough parts of meat tender and other foods sweet and juicy. Today we seem quite happy to stand there red-faced, in front of an open flame offe

A spice is a dried seed, fruit, root, bark or vegetative substance used in nutritionally insignificant quantities as a food additive to enhance the flavor, color or aroma of the food. Spices are distinguished from herbs, which are leafy, green plant parts used for flavoring purposes. Herbs, such as basil or oregano, may be used fresh, and are co...

Scientists think most contamination lies on the surface of crops, but studies have shown that it is possible for bacteria to be taken up through root systems and actually wind up inside the plants, where no amount of washing could get rid of it."In addition, he said, prewashed produce didn’t exist 25 years ago, and people today eat more raw..."
