Online Glossary edited with meticulous attitude and published as convenience for site content reference,including glossaries of related different topics,Glossary Phytochemicals are dedicated to Phytochemicals and phyto derived chemical components.Phytochemicals have been used as drugs for millennia. Hippocrates may have prescribed willow tree leaves to abate fever. Salicin, having anti-inflammatory and pain-relieving properties, was originally extracted from the white willow tree and later synthetically produced become the staple over-the-counter drug called Aspirin!
Phytochemicals are chemical compounds such as beta-carotene that occur naturally in plants. The term is generally used to refer to those chemicals that may affect health, but are not yet established as essential nutrients.While there is abundant scientific and government support for recommending diets rich in fruits and vegetables, there is only limited evidence that health benefits are due to specific phytochemicals.
There is evidence from laboratory studies that phytochemicals in fruits and vegetables may reduce the risk of cancer, possibly due to dietary fibers, polyphenol antioxidants and anti-inflammatory effects. Specific phytochemicals, such as fermentable dietary fibers, are allowed limited health claims by the US Food and Drug Administration (FDA).

nucellar beak:a structure in the ovule where nucellar tissue protrudes through the micropyle, cf. epistase, hypostase, nucellar beak, nucellar cap, nucellar endothelium, obturator.
nucellar cap:a structure in the ovule where the epidermal cells above the megasporocyte(s)/embryo sac divide periclinally, a feature that is independent of whether the ovule is crassinucellate or tenuinucellate, cf. epistase, hypostase, nucellar beak, nucellar endothelium, nucellar pad, obturator, also crassinucellate, incompletely tenuinucellate, nucellar cap, tenuinucellate, weakly crassinucellate (different degrees of development of the nucellus or of the epidermis covering it).
nucellar endothelium:a structure in the ovule where the epidermal cells underneath the integument(s) are enlarged or otherwise distinctive, a feature that is independent of whether the ovule is crassinucellate or tenuinucellate, cf. epistase, hypostase, nucellar beak, nucellar endothelium, nucellar pad, obturator, also crassinucellate, incompletely tenuinucellate, nucellar cap, tenuinucellate, weakly crassinucellate (different degrees of development of the nucellus or of the epidermis covering it).
nucellar pad:a structure in the ovule made up of radially-elongated epidermal cells at the tip of the nucellus underneath the micropyle, a feature that is independent of whether the ovule is crassinucellate or tenuinucellate, cf. epistase, hypostase, nucellar beak, nucellar endothelium, nucellar pad, obturator, also crassinucellate, incompletely tenuinucellate, nucellar cap, tenuinucellate, weakly crassinucellate (different degrees of development of the nucellus or of the epidermis covering it).
nucellus:the central tissue of an ovule of a seed plant, tissue not of epidermal origin more or less surrounding the embryo sac, sometimes much reduced, see crassinucellate, incompletely tenuinucellate, nucellar cap, nucellar endothelium, nucellar pad, tenuinucellate, weakly crassinucellate (different degrees of development of the nucellus or of the epidermis covering it), also epistase, hypostase, nucellar beak, nucellar pad, cf. antiraphe, chalaza, funicle, integument, micropyle, obturator, raphe.
nuclear:of endosperm formation, where nuclear divisions are at least initially not accompanied by cell wall formation, a syncytium being formed, cf. cellular, helobial.
Nucleic acids:DNA (deoxyribonucleic acid) and RNA (ribonucleic acid); long polymers of nucleotides.
Nucleotides:subunits of nucleic acids. Nucleotides are composed of a nitrogen-containing base (adenine, guanine, cytosine, uracil or thymine) a 5-carbon sugar (ribose or deoxyribose), and one or more phosphate groups.
nudelspritze:e.g. in some kinds of secondary pollen presentation, where the pollen is extruded in strands.
numerous:in the descriptions of floral parts, = many.
nuptial nectary:a nectary gland that is outside of the flower but that is involved in attracting pollinators, cf. extranuptial nectary.
nut:a hard, dry, indehiscent fruit formed from two or more carpels but containing only one seed, an achene in the broad sense, cf. achene s. str., caryopsis, cypsela, utricle.
nutlet:lit. "a small nut", often used to refer to any hard and more or less rounded mericarp, e.g. those of Lamiaceae, so not really a small nut at all...
nyctinasty:the response of plant parts, particularly leaves and flowers, to darkness ("sleep movements").
