E) endocytosis.

Question

Quizplus · Accepted Answer

Plant viruses typically enter the host plant through wounds, as they do not have the ability to actively penetrate the plant's cell wall. This can include damage from insects, wind, or other environmental factors. Once inside the plant cell, the virus can use various mechanisms to hijack the host's cellular machinery and replicate itself. While some specific plant viruses may have receptors that they recognize and bind to, this is not a common method of entry. Plant viruses can also be transmitted through seeds, but this is not the primary mode of infection. Endocytosis is a cellular process that involves the uptake of extracellular material into the cell, but it is not a typical mechanism for plant virus entry.
