Answer:
A virus attaches to a specific receptor site on the host cell membrane through attachment proteins in the capsid or via glycoproteins embedded in the viral envelope. The specificity of this interaction determines the host—and the cells within the host—that can be infected by a particular virus.
Explanation:
Basically it means that each virus is specific because of a certain cell makeup or cell membrane. Search up your question on google, there is a site I got this from! :)

Answer:
In plants, dead cells are not excreted, rather, they form key structural elements which support and protect living tissue as the organism grows. Two examples of useful functions are the formation of (1.) xylem vessels and (2.)sclerenchyma.
Explanation:
- Xylem vessel: mature xylem vessel is made up of dead cells called <em>vessel elements</em> aligned end-to-end; here, the ends are dissolved and the protoplasm is absent. These form long, continuous tubes that facilitate the unobstructed flow of water and minerals to other areas within plants.
- Sclerenchyma are comprised of dead cells which have secondary walls reinforced with lignin. In plants, they provide key structural support and greater mechanical strength to prevent damage or tears within the plant tissue.
