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 small dot-like structure inside the nucleus is the nucleolus. It is responsible for producing ribosomes, which are essential for protein synthesis. The nucleolus is not surrounded by a membrane and can often be seen as a distinct structure within the nucleus.

Inside of the nucleus
By saying nucleus, we mean that the DNA is contained in a membrane structure, that we call the nuclear membrane. However in prokaryotes (bacteria are examples!) the nucleus is not contained in a membrane structure. On the contrary, the DNA is rather suspended inside the cytoplasm itself in a compact form and is called a nucleoid.
In trichomes, the presence of a prominent nucleus can vary depending on the type of trichome and the specific plant species. Generally, glandular trichomes, which secrete compounds like resins and essential oils, may have a nucleus, while non-glandular trichomes, which often serve structural purposes, may not have a distinct nucleus. Overall, the cellular structure of trichomes can be quite diverse, reflecting their various functions in plants.

In Biology the nucleus of a cell is the control centre, inside the nucleus is DNA which gives it the structure and knowledge to be what it is.

the nucleus is surrounded by electrons, protons and neutrons. Inside the nucleus are quarks. (for the nucleus in an atom only)

A cell nucleus would be smaller than a cell because a cell nucleus is inside the cell, so it has to fit inside.
