Which of the following cell organelles were discovered after the introduction of electron microscope?
Which of the following cell organelles were discovered after the introduction of electron microscope?
The correct option is D Both B and C
Some
cell organelles cannot be seen with light microscopes as they cannot achieve
a high magnification. Organelles which can be seen under
light microscope are nucleus, cytoplasm, cell membrane, chloroplasts and
cell wall. Mitochondria are also visible under light microscope but detailed
study is not possible. Organelles which can
be seen under electron microscope (highest magnification to more than 200,000x)
are ribosomes, endoplasmic reticulum, lysosomes, centrioles, and Golgi
bodies. Ribosomes, endoplasmic reticulum, lysosomes, centrioles, and Golgi
bodies due their smaller size they were discovered after the introduction
of electron microscope. So the correct answer
is 'Both B and C'.
