Chlorophyll vs. Chloroplast

Chlorophyllnoun

(biochemistry) Any of a group of green pigments that are found in the chloroplasts of plants and in other photosynthetic organisms such as cyanobacteria.

Chlorophyllnoun

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.

Chlorophyllnoun

any of a group of green pigments found in photosynthetic organisms. Chlorophyll a and chlorophyll b are found in higher plants and green algae; chlorophyll c is found in certain types of marine algae. Chemically, it has a porphyrin ring with a magnesium ion bound to the four central nitrogens, and has a phytyl side chain. It is essential for photosynthesis in most plants. Chlorophyll a has formula C55H72N4O5Mg.

Chlorophyllnoun

any of a group of green pigments found in photosynthetic organisms

Chlorophyll

Chlorophyll (also chlorophyl) is any of several related green pigments found in the mesosomes of cyanobacteria and in the chloroplasts of algae and plants. Its name is derived from the Greek words χλωρός, khloros () and φύλλον, phyllon ().

Chloroplastnoun

(cytology) An organelle found in the cells of green plants, and in photosynthetic algae, where photosynthesis takes place.

Chloroplastnoun

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.

Chloroplastnoun

plastid containing chlorophyll and other pigments; in plants that carry out photosynthesis

Chloroplast

Chloroplasts are organelles that conduct photosynthesis, where the photosynthetic pigment chlorophyll captures the energy from sunlight, converts it, and stores it in the energy-storage molecules ATP and NADPH while freeing oxygen from water in plant and algal cells. They then use the ATP and NADPH to make organic molecules from carbon dioxide in a process known as the Calvin cycle.
