CHLOROPHYLL
Chlo"ro*phyll, n. Etym: [Gr. chlorophylle.] (Bot.)
Defn: Literally, leaf green; a green granular matter formed in the cells of the leaves (and other parts exposed to light) of plants, to which they owe their green color, and 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.]
CHLOROPLAST
Chlo"ro*plast, n. [Pref. chloro-+ Gr. to mold, form.] (Biol.)
Defn: A plastid containing chlorophyll, 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. In animals chloroplasts occur only in certain low forms.
CHLOROPLASTID
Chlo`ro*plas"tid, n. Etym: [Gr. plastid.] (Bot.)
Defn: A granule of chlorophyll; — also called chloroleucite.
