Conversely, it is a poor absorber of green and near-green portions of the spectrum. Hence chlorophyll-containing tissues appear green because green light, diffusively reflected by structures like cell walls, is less absorbed. [1] Two types of chlorophyll exist in the photosystems of green plants: chlorophyll a and b. [6]
Chlorophyll is the primary pigment in plants; it is a chlorin that absorbs blue and red wavelengths of light while reflecting a majority of green. It is the presence and relative abundance of chlorophyll that gives plants their green color. All land plants and green algae possess two forms of this pigment: chlorophyll a and chlorophyll b.
Variegation of fruits and wood in Ficus carica 'Panascè', a bicolor (yellow-green) common fig cultivar. This Italian cultivar is a chimera. Chimeric plants contain tissues with more than one genotype. [further explanation needed] A variegated chimera contains some tissues that produce chlorophyll and other tissues which do not. [7]
Chlorophyll is what makes leaves green. Leaves also contain carotenoids, which produce yellow, orange and brown colors. ... some have leaves that just turn brown and fall. Weather and temperature ...
A green leaf is green because of the presence of a pigment known as chlorophyll, which is inside an organelle called a chloroplast. When abundant in the leaf's cells, as during the growing season, the chlorophyll's green color dominates and masks out the colors of any other pigments that may be present in the leaf. Thus, the leaves of summer ...

When leaves change color in the autumn, it is due to the loss of green chlorophyll, which unmasks preexisting carotenoids. In this case, relatively little new carotenoid is produced—the change in plastid pigments associated with leaf senescence is somewhat different from the active conversion to chromoplasts observed in fruit and flowers.
