Which of the Following is a Difference Between Plant and Animal

Question

Which of the following is a difference between plant and animal viruses?
A) Animal viruses all use DNA as their genetic material, whereas plant viruses all use RNA
B) All plant viruses are enveloped. All animal viruses are non-enveloped.
C) All plant viruses are helical. All animal viruses are icosahedral
D) Newly assembled plant viruses often do not have to actually exit the host cell to infect new cells, whereas animal viruses almost always do.
E) Plant viruses are much larger, approaching the size of small bacteria

Accepted Answer

Plant viruses can move cell to cell through plasmodesmata, structures that connect plant cells, allowing them to infect neighboring cells without needing to exit into the extracellular space. Animal viruses typically must exit one cell and enter another to spread infection.
