Detailed explanation-1: -In the eukaryotic cell, only ribosomes are non-membranous structures.
Detailed explanation-2: -The nucleolus is a ribosome factory, composed of deoxyribonucleic acid (DNA), ribonucleic acid (RNA), and protein.
Detailed explanation-3: -The nucleolus, which is also called the nucleus of the nucleus, is not just found in either plant or animal cell. In fact, it is found in all eukaryotic cells like fungi, protists, plant and animal cells. It is involved in RNA synthesis, which is an important process for plants and animals in order to form ribosomes.
Detailed explanation-4: -The nuclei of most cells contain one or more highly staining structures callednucleoli. The nucleolus, unlike most other organelles discussed here, does not have a limiting membrane. Instead, it is simply an accumulation of large amounts of RNA and proteins of the types found in ribosomes.
