how do viruses reproduce
by latching onto a host cell and injecting its genetic info into the cell
They cant reproduce they are asexual
by bonding with another virus and reproducing
do plants have the ability to reproduce
no they lose seeds in the wind and those seeds make new plants
yes they mate with other plants
Yes because they are living and all living things can reproduce
