NEET BIOLOGY

Detailed explanation-1: -Ribosomes are the smallest cell organelles which can be seen only through an electron microscope. They are found in both prokaryotic as well as eukaryotic cells. Ribosomes are dense, round bodies which occur freely in the cytoplasm and may remain attached to the surface of the endoplasmic reticulum.

Detailed explanation-2: -Explanation: Ribosomes are composed of a unique type of RNA, rRNA, and are located within the cytoplasm of the cell and on the surface of the rough endoplasmic reticulum.

Detailed explanation-3: -Ribosomes can be found floating in the cytoplasm. They are also found attached to the surface of Endoplasmic Reticulum-making it “rough".

Detailed explanation-4: -All of the organelles in eukaryotic cells, such as the nucleus, endoplasmic reticulum, and mitochondria, are located in the cytoplasm. The portion of the cytoplasm that is not contained in the organelles is called the cytosol.

Detailed explanation-5: -The nucleolus is a spherical structure found in the cell’s nucleus whose primary function is to produce and assemble the cell’s ribosomes. The nucleolus is also where ribosomal RNA genes are transcribed.
