Virus an enigma between living and nonliving Schizophyta- Bacteria Thallophyta- Algae and Fungi Bryophyta- Moss Pterydophyta- Fern Gymnosperm- Cycas and Pinus Monocotyledonous- All the pulses and cereals Dicotyledonous- All the flowering plants Virus an enigma between living and nonliving     PROPERTIES OF VIRUS   It is the bridge between living and non-living It is living when it is present inside the body of the host and non-living when it is outside the body...
