There are three main types of trichomes: glandular, non-glandular, and cystolithic. Glandular trichomes produce and store essential oils and resins, non-glandular trichomes serve protective functions, and cystolithic trichomes contain calcium carbonate crystals for defense.
The prominent structure inside the nucleus is the nucleolus. It is primarily responsible for the synthesis of ribosomal RNA (rRNA) and the assembly of ribosome subunits. The nucleolus is not surrounded by a membrane and appears as a dense, spherical region within the nucleus, playing a crucial role in the cell's protein synthesis machinery.
The nucleolus is the prominent body in the nucleus that produces ribosomes. It is responsible for the assembly of ribosomal subunits using ribosomal RNA (rRNA) and ribosomal proteins. Ribosomes are essential for protein synthesis in cells.

In windy areas trichomes reduce evaporation and keep the leaf moist. They also reflect solar radiation and heat.
Having trichomes in trees help in defense mechanism. All trees do not have trichomes.

A prominent nucleus typically refers to a nucleus within a cell that is easily visible under a microscope due to its size, shape, or staining properties. It can indicate active cellular processes or a high level of genetic material within the nucleus. This prominence can be observed in situations such as cell division, cellular stress, or disease states.
No, the nucleus is actually one of the most prominent and important structures in the cell. It houses the cell's genetic material (DNA) and controls most of the cell's activities through gene regulation.

The fuzzy outer coating found on some leaves is called trichomes. Trichomes can serve various functions, such as protecting the plant from herbivores, reducing water loss, and reflecting sunlight.
Trichomes
It is a eukaryotic cell (it has a prominent nucleus and numerous membrane-bound organelles).
Trichomes on plants serve multiple functions, including deterring herbivores with their sharp or toxic structures, reducing water loss through their waxy coating, and providing a barrier against UV radiation. Additionally, trichomes can trap and break down insects that come into contact with them.

Stinging nettle trichomes are tiny hairs on the plant that contain irritating chemicals. When touched, these trichomes break and release the chemicals, causing a stinging sensation. This defense mechanism deters herbivores from eating the plant, protecting it from being consumed.
