An electron microscope is a type of microscope that uses a beam of electrons to produce images of small objects or structures. Because it has a higher resolving power than a light microscope, an electron microscope can produce much clearer and more detailed images of small structures than a light microscope.
There are several organelles that can only be seen in detail using an electron microscope, including:
Ribosomes: These organelles are responsible for synthesizing proteins and are made up of ribonucleic acid (RNA) and proteins. They are too small to be seen with a light microscope and can only be seen in detail using an electron microscope.
Endoplasmic reticulum (ER): The ER is a series of interconnected flattened sacs or tubes that are involved in the synthesis and transport of proteins and lipids. It has two main types: the smooth ER, which is involved in the synthesis and modification of lipids, and the rough ER, which is studded with ribosomes and is involved in the synthesis and transport of proteins.
Golgi apparatus: The Golgi apparatus is a series of flattened stacks of membranes that are involved in the modification, sorting, and transport of proteins and lipids. It is made up of cisternae, which are flattened stacks of membranes that are connected by vesicles.
Mitochondria: These organelles are responsible for generating energy in the form of ATP and are involved in a variety of other metabolic processes. They have a complex structure that includes a double membrane, cristae, and a matrix, which can only be seen in detail using an electron microscope.
Lysosomes: These organelles are involved in the digestion and breakdown of cellular waste and are made up of enzymes that can break down a variety of biomolecules. They have a characteristic spherical shape that can only be seen in detail using an electron microscope.
