The right answer is (B) contains mostly cellulose; forms the outer layer of animal cells.

The so-called pectocellulosic cell wall (consisting of pectin and cellulose) completely surrounds the cells and thereby plays the role of an internal medium of the plant or an inter-cellular medium. It is therefore involved in intercellular exchanges and communications (just like the cell membrane in animals, so A is false).

The cytoplasmic membrane or plasmalemma is located in contact with the cytoplasm, at the boundary between the inside and the outside of the cell.

1. Dr. Lairmore makes the point that veterinarians don't just treat "the animal," but approach treatment from a "one health" per
poizon [28]
Other things veterinarians are looking at is the boundary between animals, people, and the environment. Veterinarians need to work with human doctors to work on food safety, problems connected to cancer, etc. Veterinarians and human doctors can get facts from each other. The problems we face in society means that they have to cooperate with both the animal health side, the human health side, and environment side as well. One way they think of “one health” is evolving viruses. They are looking at this to find a solution by the use of comparative medicine and observing the environment.
