Question

Which cell organelle is visible under a light compound microscope?
A)Golgi body
B)Ribosomes
C)Chloroplast
D)All of the above

Answer 1

Hint: A subcellular structure which is much like an organ is called an organelle, has one or more unique functions to perform in the cell. The nuclei, which store genetic material, are among the most essential cell organelles; mitochondria, which contain chemical energy; and ribosomes, which assemble proteins.

Complete answer:
The light microscope is used to magnify the structures such as cell walls, vacuoles, cytoplasm, chloroplasts, nucleus and cell membrane of some organelles. To magnify cell elements, compound light microscopes use lenses and light. However, unless they have an electron microscope with improved magnification, they will normally reach a maximum magnification of 2000x, which is not adequate to see many other small organelles such as ribosomes, endoplasmic reticulum, lysosomes, centrioles, Golgi bodies. Although like chloroplast, it can be used to magnify organelles.

1)Some organelles are not seen under the microscope when the cells are stained in order to examine them, but as they have exactly the same refractive index, they are not adequately separated.
2)There are light-illuminated compound microscopes. For this sort of microscope, the picture

Hence, the correct answer is option (C)

Note: The nucleus, cytoplasm, cell membrane, chloroplasts and cell wall are organelles which can be seen under a light microscope. Under a light microscope, mitochondria are still visible, but thorough research is not feasible.
