It is a parasitic plant which attaches to the roots of various desert shrubs such as wild buckwheats, ragweeds, plucheas, and Tiquilia plicata and T. palmeri to obtain nutrients. As a heterotroph, the Pholisma sonorae plant lacks chlorophyll and is grayish, whitish, or brown in color. It has glandular scale-like leaves along its surface.
Autumn leaf color is a phenomenon that affects the normally green leaves of many deciduous trees and shrubs by which they take on, during a few weeks in the autumn season, various shades of yellow, orange, red, purple, and brown. [1]
Corn grey leaf spot can be an extremely devastating disease as potential yield losses range from 5 to 40 US bushels per acre (440 to 3,480 L/ha). At higher disease levels, even greater losses can result. When a corn plant's ability to store and produce carbohydrates (glucose) in the grain is diminished, yield losses take place.
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.
Star jelly (also called astromyxin, astral jelly) is a gelatinous substance sometimes found on grass and less commonly on the branches of trees. [1] According to folklore, it is deposited on the Earth during meteor showers. It is described as a translucent or grayish-white gelatin that tends to evaporate shortly after having "fallen".
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.
A sundew with a leaf bent around a fly trapped by mucilage. Mucilage is a thick gluey substance produced by nearly all plants and some microorganisms.These microorganisms include protists which use it for their locomotion, with the direction of their movement always opposite to that of the secretion of mucilage.

The epicuticular wax produced by Dudleya brittonii has the highest ultraviolet light (UV) reflectivity of any known naturally occurring biological substance. Epicuticular wax is a waxy coating which covers the outer surface of the plant cuticle in land plants. It may form a whitish film or bloom on leaves, fruits and other plant organs.
