The diagram below are illustrations of two cells labelled A and B
Study the diagram carefully and answer the questions that follow.

Name each of the parts labelled I, II, III and IV.
Which of the parts named in (a)(i) is the same as the parts labelled VI and IX in cell B?
Which of the cells is a plant cell?
Give two reasons for the answer given in (a)(iii).
Tabulate two differences between the parts labelled I and V.
Show Solution
(i) I = cell/plasma membrane, II = cytoplasm, III = nucleus , IV = vacuole
(ii) I is the same as VI (Cell membrane) and IV is the same as IX (Vacuole)
(iii) Diagram B
Reasons
1. Presence of large/ single vacuole (IX)
2. Presence of cell wall (V)
3. Rectangular shape
4. Nucleus pushed to the side/periphery
5. Cytoplasm pushed to the side
Differences between parts labelled I (Cell Membrane) and V (Cell Wall)
| I (Cell Membrane) |
V (Cell Wall) |
| Present in all types of cells, in humans, animals, plants, bacteria, etc. |
Present only in plants and in some fungi, bacteria, algae. |
| Semi-permeable |
Completely or fully permeable |
| Flexible |
Thick and rigid |
| Made up of proteins and lipids |
Made up of cellulose |
