NEET BIOLOGY

Detailed explanation-1: -A cell is the smallest unit of life. Most cells are so small that they cannot be viewed with the naked eye. Therefore, scientists must use microscopes to study cells. Electron microscopes provide higher magnification, higher resolution, and more detail than light microscopes.

Detailed explanation-2: -With a few exceptions, individual cells cannot be seen with the naked eye, so scientists must instead use microscopes (micro-= “small”; -scope = “to look at”) to study them. A microscope is an instrument that magnifies objects otherwise too small to be seen, producing an image in which the object appears larger.

Detailed explanation-3: -Contemporary light microscopes are able to magnify objects up to about a thousand times. Since most cells are between 1 and 100 m in diameter, they can be observed by light microscopy, as can some of the larger subcellular organelles, such as nuclei, chloroplasts, and mitochondria.

Detailed explanation-4: -A microscope is an instrument that can be used to observe small objects, even cells. The image of an object is magnified through at least one lens in the microscope. This lens bends light toward the eye and makes an object appear larger than it actually is.

Detailed explanation-5: -So, the correct answer is ‘Ribosome’
