Question

The instrument used to observe and study the organelles of the cell is __________.

• A. Compound microscope
• B. Electron microscope
• C. Transmission electron microscope
• D. Magnifying glass

Answer 1

Answer: (C)

Transmission electron microscope

The cells of the living organism are very tiny and can be observed using a compound microscope. Cell organelles present embedded into the cytoplasm are still further small and can be viewed using a transmission electron microscope. The nucleus, mitochondria, chloroplasts, Golgi bodies etc. are all organelles which can be studied in details using a transmission electron microscope. Most organelles are not clearly visible by light microscopy, and those that can be seen(such as the nucleus, mitochondria, and Golgi) can't be studied in detail because their size is close to the limit of resolution of the light microscope. The detailed structure of organelles only became clear after the development of the transmission electron microscope(TEM), which made it possible to look at individual organelles at high resolution.

So, the correct answer is 'Transmission electron microscope'
