An albino corn plant with no chlorophyll (left) beside a normal plant (right) In botany , chlorosis is a condition in which leaves produce insufficient chlorophyll . As chlorophyll is responsible for the green color of leaves, chlorotic leaves are pale, yellow, or yellow-white.
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 ...
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]

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]
Prickles on a blackberry branch. In plant morphology, thorns, spines, and prickles, and in general spinose structures (sometimes called spinose teeth or spinose apical processes), are hard, rigid extensions or modifications of leaves, roots, stems, or buds with sharp, stiff ends, and generally serve the same function: physically defending plants against herbivory.
Some experimentation on plant litter from marcescent trees indicates that keeping the leaves above ground may increase the amount of photodegradation the leaves are exposed to. Because some marcescent species' leaves do not decompose well, the increased photodegradation may allow them to decompose better once they finally fall off the tree.
An apple tree sprout is being converted to a branched, fruit-bearing spur by an arborist. Numbers show the sequence of cuts, which occurred during two years. Plants form new tissue in an area called the meristem, located near the tips of roots and shoots, where active cell division takes place.
