plash
— Navneord
– Engelsk
～ the sound like water splashing
plasm
— Navneord
– Engelsk
～ the protoplasm of the germ cells that contains chromosomes and genes
plasm
— Navneord
– Engelsk
～ the colorless watery fluid of the blood and lymph that contains no cells, but in which the blood cells (erythrocytes, leukocytes, and thrombocytes) are suspended

plasma cell
— Navneord
– Engelsk
～ a cell that develops from a B lymphocyte in reaction to a specific antigen; found in bone marrow and sometimes in the blood
plasma
— Navneord
– Engelsk
～ a green slightly translucent variety of chalcedony used as a gemstone
plasma
— Navneord
– Engelsk
～ (physical chemistry) a fourth state of matter distinct from solid or liquid or gas and present in stars and fusion reactors; a gas becomes a plasma when it is heated until the atoms lose all their electrons, leaving a highly electrified collection of nuclei and free electrons; "particles in space exist in the form of a plasma"
plasma membrane
— Navneord
– Engelsk
～ a thin membrane (a double layer of lipids) enclosing the cytoplasm of a cell; proteins in the membrane control passage of ions (like sodium or potassium or calcium) in and out of the cell; "all cells have a cell membrane"
plasma physics
— Navneord
– Engelsk
～ the branch of physics concerned with matter in its plasma phase
plasmablast
— Navneord
– Engelsk
～ the precursor of a plasma cell
plasmacyte
— Navneord
– Engelsk
～ a cell that develops from a B lymphocyte in reaction to a specific antigen; found in bone marrow and sometimes in the blood
plasmacytoma
— Navneord
– Engelsk
～ neoplasm of plasma cells (usually in bone marrow)
plasmapheresis
— Navneord
– Engelsk
～ plasma is separated from whole blood and the rest is returned to the donor
plasmid DNA
— Navneord
– Engelsk
～ a small cellular inclusion consisting of a ring of DNA that is not in a chromosome but is capable of autonomous replication
plasmid

– Engelsk
～ a small cellular inclusion consisting of a ring of DNA that is not in a chromosome but is capable of autonomous replication
plasmin
— Navneord
– Engelsk
～ an enzyme that dissolves the fibrin of blood clots
plasminogen activator
— Navneord
– Engelsk
～ protease produced in the kidney that converts plasminogen to plasmin and so initiates fibrinolysis
plasminogen
— Navneord
– Engelsk
～ an inactive form of plasmin that occurs in plasma and is converted to plasmin by organic solvents
Plasmodiidae
— Navneord
– Engelsk
～ malaria parasites
Plasmodiophora
— Navneord
– Engelsk
～ type genus of Plasmodiophoraceae comprising minute plant parasitic fungi similar to and sometimes included among the slime molds
