Assess the following statements, and classify them according to whether they refer to viral particles or living cells.

O May have a cell wall

O genome may be exclusively RNA

O center layer is predominate protein

O contain ribosomes

O are obligate parasites

O always have a plasma

Answer: Characteristics of viral particles from the options given are;

1. Parasitic obligate.

2. The centre layer is predominate protein.

3. Genome may be RNA exclusively.

The characteristics of living cells are:

1. May have cell wall.

2. Contain ribosomes.

3. Always of plasma.

Explanation:

Living cells are the basic unit of life, that contain the fundamental molecules in which the living things are composed of. Living cells have plasma membrane, ribosomes, cytoplasm and DNA.

Viral particle is a structure or infectious agents that enter another cell and replicates itself in a living cell. The are obligates parasite, that have no cell wall, they have center layer of protein, the genome contain either DNA or RNA, they reproduce only in living cells, they lack cytoplasm and organelles.
