Complete the passage to compare a bacterial cell with a plant cell. Both a bacterial cell and a plant cell possess a cell wall, but the chief constituent of the bacterial cell wall is ............................................... rather than cellulose. Protein synthesis in both cells uses the same organelle, although a bacterial cell has only smaller, 70S, ............................................... . A bacterial cell lacks a large ............................................... that is enclosed by a tonoplast.
Explain why scientists maintain the protoplasts in a solution with the same water potential as the cell.
Describe the structure of a cellulose molecule and of a cellulose microfibril.
Name one substance that could be added to the network made by the cellulose microfibrils as the cell wall is formed.
Name the kind of plant cell that may have been used to make the protoplast shown in Fig. 2.2.
