What Does A Virus Look Like Under A Microscope
Camila Farah
What you re seeing above is a scanning electron microscope image in false colour showing the covid 19 virus from a patient in the us.
What s shown in the media are representational graphics not photos. The spikes are blue not red. It requires an electron microscope which means very few people have actually seen one. However there are three more severe strains of the virus.
The strains 229e and nl63 are classified as alphacoronaviruses while oc43 and hku1 are betacoronaviruses.

Niaid 2 of 8 a colorized scanning electron micrograph of an apoptotic cell blue green heavily infected with sars cov 2 virus particles yellow isolated from a patient sample. Viruses are particles that are considered obligatory parasites as they don t grow or survive outside a living organism.
A virus cannot be seen with a microscope they re far too small. Niaid rml the image above was captured with a transmission electron microscope. The virus can be seen only by using a microscope. It means that for the real form of the virus.

Virus under the microscope. When the structure of a virus is viewed under a powerful microscope it may be icosahedral or helical. The viral particles are coloured yellow as it emerges from the surface of a cell which is coloured blue and pink. Because viruses are tiny as compared to bacteria they cannot be viewed with a compound microscope.
These particles are composed of a protein coat that envelopes the genetic material and is typically referred to as a nucleocapsid. For example the image below is what a coronavirus cell really looks like.
