Which viruses enter the host cell as a whole?

Explanation

Animal viruses can enter host cells as whole particles because animal cells lack rigid walls, using processes like membrane fusion or endocytosis before uncoating their genome. In contrast, plant viruses cannot enter as complete virions due to the tough cell wall; they depend on wounds or insect vectors to introduce only their genome. Bacteriophages also do not enter entirely-they attach to bacteria and inject their genetic material while the capsid remains outside.
