Cell that the virus invades and takes over

Organism that lives on the cell and causes it harm

Something that causes harm to the cell

Why do scientists classify viruses as non-living?

They need a host's energy because they do not have their own energy

A virus is considered non-living because...

It does not have all the characteristics of life

Which statement regarding viruses is true?

a virus can only reproduce inside of a living cell

viruses are generally larger than cells

Viruses share which two of the following features with living things?

contains universal genetic code

ability to maintain homeostasis

How does a virus cause a person to develop the common cold?

invades the host cell to reproduce

removes energy from the host cell

produces toxins in the host cell

protects the host cell from bacteria

Which of the following correctly describes viruses?

non-living because they cannot reproduce on their own

non-living because they grow and develop

living because they can use energy

living because they can maintain homeostasis

A virus is considered non-living because...

It does not have all the characteristics of life

Which of the following characteristics is shared by viruses and living cells? Both viruses and living cells -

contain nucleic acids such as DNA or RNA.

have a nucleus, as well as a cell wall.

can replicate independently of a host cell.

use organelles to perform life functions.

What factor characterizes viruses as nonliving particles rather than cells? Viruses -

have no metabolism of their own.

can survive only in intercellular spaces.

take over a host’s body systems.

Which statement best explains why viruses are considered to be nonliving?

They are unable to reproduce independently.

They are only able to be viewed with a microscope.

They have different types of proteins.

What evidence would prevent scientists from classifying viruses as living organisms?

Viruses require a host cell to reproduce.

Some viruses use RNA (not DNA) as genetic material.

Some viruses do not contain any proteins or carbohydrates.

What trait do viruses possess that is associated with living things?

They contain genetic material as DNA or RNA.

They contain organelles within their membranes.

They grow and develop complexity over their lifetimes.

They reproduce only within a host cell.

After learning about viruses in Biology class, Sam decides to have his cat vaccinated against feline leukemia virus. According to cell theory, are viruses, such as feline leukemia, considered living things?

No, because they are not composed of cells.

Yes, because they can reproduce

Yes, because they are composed of cells

No, because they cannot adapt to their environment

Viruses have structures that allow them to inject their genetic material directly into the DNA of the host cell. This strategy benefits the virus in that –

the virus uses the host’s machinery to replicate.

the host cell is turned into a virus.

mutations are introduced into the host cell.

it is able to transform into a host cell.

All living organisms use energy. They also grow and reproduce. What is another characteristic of all living organisms?

All living organisms are composed of one or more cells.

All living organisms must consume food in order to acquire nutrition.

All living organisms consist of many cells with specialized organelles.

All living organisms can produce glucose through photosynthesis.

What is the role of a vaccine?

Help build immunity to the virus
