Vital Viruses!
-what does a virus look like?
A virus is a round shape that is made up
from five different parts; the inside of the virus cell doesn't have a nucleus
(unlike other viruses) instead the cell has genetic material floating around in
the centre of the virus cell. There is a thin layer of protein that surrounds
the genetic material and acts as a protective ball, there is a final protein
bilayer that surrounds the cell. On the outside of the virus there are many
spikes that act like a key, these spikes determine which cell the virus can and
cannot invade

-unicellular, multicellular or non-cellular?
A virus is not made of cells so therefore it is not classed as 'living' hence why it cannot be grouped as multi, uni or non-cellular
-where are viruses found?
Viruses are found virtually
anywhere! They inhabit food, plants, soil, water and even the air! Basically
they are found wherever there are viable hosts to
infect.
-how does a virus take in nutrients
A virus does not require nutrition as it is not a living cell.

-how does a virus reproduce?
A virus doesn't reproduce like other cells, it multiplies in numbers by injecting its own DNA into the host cell. This can do one of two
things;
1- destroy the host cell's DNA/RNA and replace it with the virus' own genetic material
creating another single virus cell.
2- combine with the host cell's DNA/RNA so that every time that cell reproduces it
creates more virus cells.
-Are viruses used in food production, medical applications or other situations?
Viruses are not just things that make you ill, they are also used to create pesticides designed to kill pests and protect our plants and crops. The power of the virus
is also harnessed in medical applications; it is used as a carrier and is harnessed to carry the anti-bodies to the infection, or site of pain.
