Under the electron microscope, which cell organelle is visible as either clusters or single, small dots that float freely in the cytoplasm?

Ribosomes

The correct answer is Option (2)- Ribosomes

Under the electron microscope, Ribosomes are visible as either clusters or single, small dots that float freely in the cytoplasm.

Explanation:

• Ribosomes are cellular structures responsible for protein synthesis.

Under the electron microscope, ribosomes appear as small dots, and they can be found either as free-floating particles in the cytoplasm or attached to the endoplasmic reticulum. When free floating, they appear as single dots or clusters of dots under high magnification of an electron microscope.

• They play a crucial role in the translation of genetic information into proteins.

So, the correct answer is Ribosomes.
