Roots & Shoots was founded by Jane Goodall, DBE in 1991, to bring together youth from preschool to university age to work on environmental, conservation, and humanitarian issues. [2] The organization has local chapters in over 140 countries with over 8000 local groups worldwide that involve nearly 150,000 youth.
The rhizome also retains the ability to allow new shoots to grow upwards. [4] A rhizome is the main stem of the plant that runs typically underground and horizontally to the soil surface. [5] [6] Rhizomes have nodes and internodes and auxiliary buds. [7] Roots do not have nodes and internodes and have a root cap terminating their ends. [8]
Because roots are seldom harvested, the harvest index is the amount of marketable product (often the seeds), relative to the total above-ground biomass. Alternative terminology that has been used are Leaf, Stem and Root Mass Ratios, or shoot:root or root:shoot ratios.
Root sprouts and basal shoots can be used to propagate woody plants. Root sprouts can be dug or severed with some of the roots still attached. As for basal shoots, stool beds involve cutting a juvenile plant proximate to the surface of the soil and heaping soil over the cut so that basal shoots will form adventitious roots and later can be ...
Consumers commonly acquire cress as seeds or (in Europe) from markets as boxes of young live shoots. [ 6 ] Edible shoots are typically harvested in one to two weeks after planting, when they are 5–13 cm (2–5 in) tall.
Adventitious buds develop from places other than a shoot apical meristem, which occurs at the tip of a stem, or on a shoot node, at the leaf axil, the bud being left there during primary growth. They may develop on roots or leaves, or on shoots as a new growth. Shoot apical meristems produce one or more axillary or lateral buds at each node.
A stem is one of two main structural axes of a vascular plant, the other being the root. It supports leaves, flowers and fruits, transports water and dissolved substances between the roots and the shoots in the xylem and phloem, engages in photosynthesis, stores nutrients, and produces new living tissue.

Adventitious roots arise out-of-sequence from the more usual root formation of branches of a primary root, and instead originate from the stem, branches, leaves, or old woody roots. They commonly occur in monocots and pteridophytes, but also in many dicots , such as clover ( Trifolium ), ivy ( Hedera ), strawberry ( Fragaria ) and willow ( Salix ).
