A little grain a small particle; a pellet.

An albuminoid substance which occurs in minute grains ("protein granules") in maturing seeds and tubers; -- supposed to be a modification of protoplasm.

That part of the starch granule or granulose which is soluble in water.

nd through which all ordinary assimilation of plant food takes place. Similar chlorophyll granules have been found in the tissues of the lower animals. [Written also chlorophyl.]

orophyll, developed only in cells exposed to the light. Chloroplasts are minute flattened granules, usually occurring in great numbers in the cytoplasm near the cell wall, and consist of a colorless ground substance saturated with chlorophyll pigments. Under light of varying intensity they exhibit phototactic movements…

A granule of chlorophyll; -- also called chloroleucite.

A peculiar rounded granule of some mineral, usually enstatite or chrysolite, found imdedded more or less aboundantly in the mass of many meteoric stones, which are hence called chondrites.

One of the granules of protoplasm, which in mass give color to the part of the plant containing them.

A term applied by Brücke to a substance present in small amount in starch granules, colored red by iodine.

One of the fine granules contained in the protoplasm of a pollen grain.

One of the imaginary granules or atoms which, according to Darwin's hypothesis of pangenesis, are continually being thrown off from every cell or unit, and circulate freely throughout the system, and when supplied with proper nutriment multiply by self-division and ultimately develop into cells like those from which th…

To raise in granules or small asperities; to make rough on the surface.

The main constituent of the starch grain or granule, in distinction from the framework of cellulose. Unlike cellulose, it is colored blue by iodine, and is converted into dextrin and sugar by boiling acids and amylolytic ferments.

One of certain very minute whitish or colorless granules occurring in the protoplasm of plants and supposed to be the nuclei around which starch granules will form.
