Short answer

Viruses vary in shape.

Step-by-step solution

Introduction

A cellular microorganisms are viruses. They are made up of a nucleic acid core, a proteinaceous capsid that surrounds it, and an envelope. They come in a variety of forms and sizes.

They are categorised into four categories based on their shape: filamentous, icosahedral, enveloped, and head and tail. Viruses do not all have the same form.

Filamentous viruses are cylindrical and lengthy in shape, therefore they can have a long shape.

Viruses have the ability to preserve their form.

Explanation

Viruses come in a variety of forms and sizes.

These include filamentous viruses, which are cylindrical and long, icosahedral viruses, which are spherical, enveloped viruses, which have a membrane surrounding the capsid, and head and tail viruses, which have a head like icosahedral viruses and a tail like filamentous viruses.
