Explanation / Answer

1. Icosahedral virus comprises twenty identical triangular faces, capsid and three axis of rotational symmetry. The symmetry of different axis is either twofold, threefold or fivefold. Example - herpes virus.

Filamentous (helical) virus are symmetrical and helical in nature. Capsid contains coiled genome and capsid can increase in size with the increase in genome. Example includes Ebola virus.
