These bristles can embed themselves in the other animal's skin or eyes, causing physical irritation, usually to great discomfort. The term "hairs" is technically a misnomer, as only mammals possess true hairs. [1] The scientific term for plant hairs is trichomes.
Stiff hairs or trichomes without the ability to inject irritating compounds occur on the leaves and stems of many plants. They appear to deter feeding insects to some degree by impeding movement and restricting access to the surface of the stem or leaf. Some plants have glandular hairs, either as well as non-glandular hairs or instead of them.
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.
Although trichomes are used for protection, they can be disadvantageous for plants at times because trichomes may reflect light away from the plant that can be used to photosynthesize. [2] The cuticle is a layered structure of waxes and hydrocarbons located on the outer layer of the epidermis which also helps protect the plant from stress. [2]
Researchers compared how three antioxidants affected gray hair outcomes in mice: hesperetin, diosmetin, and luteolin, and found that one helped mitigate hair graying.
Trichomes usually reverse their polarity randomly with an average period on the order of minutes to hours. [100] [101] Many species also form a semi-rigid sheath that is left behind as a hollow tube as the trichome moves forward. When the trichome reverses direction, it can move back into the sheath or break out. [102] [3]
The name − pronounced KRUNG-bin− is Thai for airplane. Appropriately, the group's music often lifts you to a somewhat liminal state, swaying between altitudes and time zones.
