Question

Viruses do not possess all the characteristics of life. Identify those characteristics that viruses display and those they don’t display. made up of one or more cells has a defined boundary uses energy exhibits growth and development possesses internal organization eliminates waste

Answer 1

Viruses are the biological, infective agents which reproduce inside the body of the host. they have a definite boundary around them separating their genetic material from the surroundings.

The viruses display made up of the core of the genetic material, that is the DNA (deoxyribonucleic acid), or the RNA (Ribonucleic acid). They are not made up of the cells.

The viruses never exhibits the signs of growth and development, and there is no internal organization in the viruses as there are no organs present.

Since, they never grow or have metabolic process, they have no need to eliminate waste either.

Answer 2

Answer:

Characters displayed by virus -1. has a defined boundary

Characters not displayed by virus-1. made up of one or more cells

                                               2. uses energy

                                               3. exhibits growth and development processes

                                               4.  internal organization

                                               5. eliminates waste

Virus is a biological agent which requires a living host cell to complete its life cycle as they replicate inside a living host.

Outside the host cells they exist as a capsid or protein coat enclosing the genetic material- DNA or RNA which, codes for the virus elements. They lack cell organelle, cytoplasm and internal organization. so they are not cellular.

They are metabolically inert that is not able to perform any metabolic functions outside host, so, not use energy and produce any waste.

Thus, they do not show most of the characters of a cell.
