Detailed explanation-1: -Trichomes are the epidermal hairs that grow on the plant’s stem. Unicellular trichomes, which look like hairs, can be seen in dicot stems. It is not present in monocot stems. When insects come into touch with the plant leaves, some trichomes produce mucilage that traps them.

Detailed explanation-2: -Trichomes usually originate from epidermal cells and are ubiquitous in many plant families, showing great diversity in morphology, cellular structure and function (Uphof, 1962).

Detailed explanation-3: -Trichomes are shoot epidermal hairs, found on the majority of plants, and are composed of either single or several cells (Esau, 1977).

Detailed explanation-4: -On the stem the epidermal hairs are called trichomes. The trichomes in the shoot system are usually multicellular.

Detailed explanation-5: -Multicellular glandular trichomes are epidermal outgrowths characterized by the presence of a head made of cells that have the ability to secrete or store large quantities of specialized metabolites.
