Metabolism :: Metabolism (n.) The act or process, by which living tissues or cells take up and convert into their own proper substance the nutritive material brought to them by the blood, or by which they transform their cell protoplasm into simpler substances, which are fitted either for excretion or for some special purpose, as in the manufacture of the digestive ferments. Hence, metabolism may be either constructive (anabolism), or destructive (katabolism)..

Entoplasm :: Entoplasm (n.) The inner granular layer of protoplasm in a developing ovum.

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..

Plasmodium :: Plasmodium (n.) A naked mobile mass of protoplasm, formed by the union of several amoebalike young, and constituting one of the stages in the life cycle of Mycetozoa and other low organisms..

Karyostenosis :: Karyostenosis (n.) Direct cell division (in which there is first a simple division of the nucleus, without any changes in its structure, followed by division of the protoplasm of the karyostenotic mode of nuclear division..

Sarcode :: Sarcode (n.) A name applied by Dujardin in 1835 to the gelatinous material forming the bodies of the lowest animals; protoplasm.

Plastidule :: Plastidule (n.) One of the small particles or organic molecules of protoplasm.

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..

Gymnoplast :: Gymnoplast (n.) A cell or mass of protoplasm devoid of an envelope, as a white blood corpuscle..

Protoplasmatic :: Protoplasmatic (a.) Protoplasmic.

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..

Spermoplasma :: Spermoplasma (n.) The protoplasm of the sperm cell.

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

Anastate :: Anastate (n.) One of a series of substances formed, in secreting cells, by constructive or anabolic processes, in the production of protoplasm; -- opposed to katastate..

Bioplasm :: Bioplasm (n.) A name suggested by Dr. Beale for the germinal matter supposed to be essential to the functions of all living beings; the material through which every form of life manifests itself; unaltered protoplasm.
