Trichomes

Trichomes are small outgrowths on plants, fungi and other organisms that can help in identification and provide protection. They are microscopic projections of cells found on the surfaces of plants and may have a variety of shapes and sizes. Trichomes provide protection to plants by producing chemicals, trapping air, and providing a physical barrier that can help to repel pests and diseases. Trichomes can also play an important role in a plant's environment by cooling the air and lower light intensity, which can enable the plant to survive high temperatures or drought. They are also important in the process of pollination as they provide sticky surfaces that bees and other insects use to move pollen. Trichomes are therefore important for the survival of plants and have a variety of uses in biotechnology and pharmacology.
