Podsemyadolnoe knee - the lower portion of the stem between the cotyledon node and the

Kidney renewal - wintering kidney perennial, from which, after a period of rest develops 
escape. 
Kidney - plants - rudimentary, not yet unfolded escape, on top of which is the growth cone. 
Radial spines - thin, numerous spines. There are compact bodies, occupy a special place in 
the structure of the individual; dispersive bodies scattered in the specimen. 
The reproductive organs of plants - flowers, fruits and seeds. 
Rhizoids - threadlike formation in mosses, ferns prothallia, lichens, algae, and some fungi. 
Rhizoids perform root functions: fixing to a substrate, extract water and nutrients. 
Rhizosphere - the soil surrounding the roots of the plants at a distance of 2-3 mm, wherein 
a significant biological activity and a high content of microorganisms involved secretions roots. 
Microorganisms convert poorly soluble compounds into easily digestible plants. 
Stigma  -  sticky  and  furry  upper  part  of  the  pistil  in  the  flower,  pollen  receptive  and

fibers  and  sklereid.  Sclerenchyma  gives  plants  the  stiffness  bodies,  determine  their  position  in 
space. Sclerenchyma is spinning raw materials. 
Wood structure - in wood anatomy  - the size of which is proportional to the amount and 
the order of the cell tissues that make up the tree. 
Sperm - in gymnosperms and angiosperms - male sex cell vehicle running passively as the
