Detailed explanation-1: -After treating a sample of plant tissue, a scientist identifies structures made mostly of three chemical compounds: cellulose, proteins and phospholipids. Which treatment did the plant tissue most likely undergo? The cytoplasm and organelles were removed, leaving only the cell membrane and cell wall.
Detailed explanation-2: -The cellulose molecules provide tensile strength to the primary cell wall. Each molecule consists of a linear chain of at least 500 glucose residues that are covalently linked to one another to form a ribbonlike structure, which is stabilized by hydrogen bonds within the chain (Figure 19-70).
Detailed explanation-3: -The endoplasmic reticulum can either be smooth or rough, and in general its function is to produce proteins for the rest of the cell to function. The rough endoplasmic reticulum has on it ribosomes, which are small, round organelles whose function it is to make those proteins.
