Detailed explanation-1: -Non membranous organelles of a cell include cytoskeleton, microvilli, centrioles, cillia, flagella, ribosomes while membranous organelles include mitochondria, nucleus, endoplasmic reticulum, golgi apparatus, lysosomes, peroxisomes, vesicles.

Detailed explanation-2: -Ribosomes are the cell organelles without cell membranes and are present in both prokaryotic and eukaryotic cells. They are responsible for protein synthesis.

Detailed explanation-3: -What are Cell Organelles? The cellular components are called cell organelles. These cell organelles include both membrane and non-membrane bound organelles, present within the cells and are distinct in their structures and functions.

Detailed explanation-4: -In this sense, ribosomes and nucleosomes are not regarded as organelles because they are not bounded by membranes. In the same way, lysosomes and vacuoles, would not qualify as organelle because they are single-membrane bounded cytoplasmic structures.
