Detailed explanation-1: -Mitochondria are self-replicating organelles that occur in various numbers, shapes, and sizes in the cytoplasm of all eukaryotic cells.

Detailed explanation-2: -Ribosome. A ribosome is the cellular machinery responsible for making proteins. There are many ribosomes in each cell, each made up of two subunits. These two subunits lock around the messenger RNA and then travel along the length of the messenger RNA molecule reading each three-letter codon.

Detailed explanation-3: -However, eukaryotic cells that specialize in producing proteins have particularly large numbers of ribosomes.

Detailed explanation-4: -All living cells contain ribosomes, tiny organelles composed of approximately 60 percent ribosomal RNA (rRNA) and 40 percent protein. However, though they are generally described as organelles, it is important to note that ribosomes are not bound by a membrane and are much smaller than other organelles.

Detailed explanation-5: -Cytoplasmic organelles are “little organs” that are suspended in the cytoplasm of the cell. Each type of organelle has a definite structure and a specific role in the function of the cell. Examples of cytoplasmic organelles are mitochondrion, ribosomes, endoplasmic reticulum, golgi apparatus, and lysosomes.
