Plant Roots
|
D018517 |
[The usually underground portions of a plant that serve as support, store food, and through which water and mineral nutrients enter the plant. (From American Heritage Dictionary, 1982; Concise Dictionary of Biology, 1990)

|
Plant Shoots
|
D018520 |
[New immature growth of a plant including stem, leaves, tips of branches, and SEEDLINGS.

Plant Somatic Embryogenesis Techniques
|
D058439 |
[The process of embryo initiation in culture from vegetative, non-gametic, sporophytic, or somatic plant cells.

|
Plant Stems
|
D018547 |
[Parts of plants that usually grow vertically upwards towards the light and support the leaves, buds, and reproductive structures. (From Concise Dictionary of Biology, 1990)

|
Plant Stomata
|
D054046 |
[Closable openings in the epidermis of plants on the underside of leaves. They allow the exchange of gases between the internal tissues of the plant and the outside atmosphere.

|
Plant Structures
|
D018514 |
[The parts of plants, including SEEDS.

|
Plant Transpiration
|
D018526 |
[The loss of water vapor by plants to the atmosphere. It occurs mainly from the leaves through pores (stomata) whose primary function is gas exchange. The water is replaced by a continuous column of water moving upwards from the roots within the xylem vessels. (Concise Dictionary of Biology, 1990)

|
Plant Tubers
|
D035281 |
[An enlarged underground root or stem of some plants. It is usually rich in carbohydrates. Some, such as POTATOES, are important human FOOD. They may reproduce vegetatively from buds.

Plant Tumor-Inducing Plasmids
|
D036741 |
[Plasmids coding for proteins which induce PLANT TUMORS. The most notable example of a plant tumor inducing plasmid is the Ti plasmid found associated with AGROBACTERIUM TUMEFACIENS.

|
Plant Tumors
|
D010941 |
[A localized proliferation of plant tissue forming a swelling or outgrowth, commonly with a characteristic shape and unlike any organ of the normal plant. Plant tumors or galls usually form in response to the action of a pathogen or a pest. (Holliday, P., A Dictionary of Plant Pathology, 1989, p330)

|
Plant Vascular Bundle
|
D058526 |
[A strand of primary conductive plant tissue consisting essentially of XYLEM, PHLOEM, and CAMBIUM.

|
Plant Viral Movement Proteins
|
D053830 |
[Viral proteins that facilitate the movement of viruses between plant cells by means of PLASMODESMATA, channels that traverse the plant cell walls.
] |
|
Plant Viruses
|
D010942 |
[Viruses parasitic on plants.
] |
|
Plant Weeds
|
D057685 |
[A plant growing in a location where it is not wanted, often competing with cultivated plants.
] |
|
Plantaginaceae
|
D000068377 |
[A plant family of order Lamiales. The Plantago genus is best known. Lesser known members include Hippuris, Littorella and Callitriche.
] |
|
Plantago
|
D010943 |
[A plant genus of the family Plantaginaceae. The small plants usually have a dense tuft of basal leaves and long, leafless stalks bearing a terminal spike of small flowers. The seeds, known as PSYLLIUM, swell in water and are used as laxatives. The leaves have been used medicinally.

|
Plantar Plate
|
D000069262 |
[Fibrocartilaginous ligament at the metatarsophalangeal and the interphalangeal joint of the toe.
] |
|
Plantibodies
|
D046549 |
[Recombinant antibodies produced in TRANSGENIC PLANTS. The plants serve as BIOREACTORS to produce the antibodies for medical use or industrial processes.
] |
|
Plants
|
D010944 |
[Multicellular, eukaryotic life forms of kingdom Plantae (sensu lato), comprising the VIRIDIPLANTAE; RHODOPHYTA; and GLAUCOPHYTA; all of which acquired chloroplasts by direct endosymbiosis of CYANOBACTERIA. They are characterized by a mainly photosynthetic mode of nutrition; essentially unlimited growth at localized regions of cell divisions (MERISTEMS); cellulose within cells providing rigidity; the absence of organs of locomotion; absence of nervous and sensory systems; and an alternation of haploid and diploid generations.

|
Plants, Edible
|
D010945 |
[An organism of the vegetable kingdom suitable by nature for use as a food, especially by human beings. Not all parts of any given plant are edible but all parts of edible plants have been known to figure as raw or cooked food: leaves, roots, tubers, stems, seeds, buds, fruits, and flowers. The most commonly edible parts of plants are FRUIT, usually sweet, fleshy, and succulent. Most edible plants are commonly cultivated for their nutritional value and are referred to as VEGETABLES.
