Protoplasm :: Protoplasm (n.) The viscid and more or less granular material of vegetable and animal cells, possessed of vital properties by which the processes of nutrition, secretion, and growth go forward; the so-called physical basis of life; the original cell substance, cytoplasm, cytoblastema, bioplasm sarcode, etc..

Ovum :: Ovum (n.) A more or less spherical and transparent mass of granular protoplasm, which by a process of multiplication and growth develops into a mass of cells, constituting a new individual like the parent; an egg, spore, germ, or germ cell. See Illust. of Mycropyle..

Monadiform :: Monadiform (a.) Having the form of a monad; resembling a monad in having one or more filaments of vibratile protoplasm; as, monadiform young..

Oospere :: Oospere (n.) An unfertilized, rounded mass of protoplasm, produced in an oogonium..

Karyokinesis :: Karyokinesis (n.) The indirect division of cells in which, prior to division of the cell protoplasm, complicated changes take place in the nucleus, attended with movement of the nuclear fibrils; -- opposed to karyostenosis. The nucleus becomes enlarged and convoluted, and finally the threads are separated into two groups which ultimately become disconnected and constitute the daughter nuclei. Called also mitosis. See Cell development, under Cell..

Cytode :: Cytode (n.) A nonnucleated mass of protoplasm, the supposed simplest form of independent life differing from the amoeba, in which nuclei are present..

Osteoblast :: Osteoblast (n.) One of the protoplasmic cells which occur in the osteogenetic layer of the periosteum, and from or around which the matrix of the bone is developed; an osteoplast..

Mycoprotein :: Mycoprotein (n.) The protoplasmic matter of which bacteria are composed.

Rejuvenescence :: Rejuvenescence (n.) A method of cell formation in which the entire protoplasm of an old cell escapes by rupture of the cell wall, and then develops a new cell wall. It is seen sometimes in the formation of zoospores, etc..

Demilune :: Demilune (n.) A crescentic mass of granular protoplasm present in the salivary glands.

Intracellular :: Intracellular (a.) Within a cell; as, the intracellular movements seen in the pigment cells, the salivary cells, and in the protoplasm of some vegetable cells..

Hygroplasm :: Hygroplasm (n.) The fluid portion of the cell protoplasm, in opposition to stereoplasm, the solid or insoluble portion. The latter is supposed to be partly nutritive and partly composed of idioplasm..

Ectoplasm :: Ectoplasm (n.) The outer transparent layer of protoplasm in a developing ovum.

Pseudopod :: Pseudopod (n.) Any protoplasmic filament or irregular process projecting from any unicellular organism, or from any animal or plant call..

Blastema :: Blastema (n.) The structureless, protoplasmic tissue of the embryo; the primitive basis of an organ yet unformed, from which it grows..

Germogen :: Germogen (n.) A polynuclear mass of protoplasm, not divided into separate cells, from which certain ova are developed..

Cyclosis :: Cyclosis (n.) The circulation or movement of protoplasmic granules within a living vegetable cell.

Vacuole :: Vacuole (n.) A small air cell, or globular space, in the interior of organic cells, either containing air, or a pellucid watery liquid, or some special chemical secretions of the cell protoplasm..

Chromatophore :: Chromatophore (n.) One of the granules of protoplasm, which in mass give color to the part of the plant containing them..

Plastide :: Plastide (n.) One of the many minute granules found in the protoplasm of vegetable cells. They are divided by their colors into three classes, chloroplastids, chromoplastids, and leucoplastids..
