1. Strong sugar solution
2. Cell wall
3. Protoplasm
4. Large vacuole
5. Nucleus
Figure

Study the diagram and answer the questions that follow:
(i) What is the state of the cell shown in the diagram
(ii) Name the structure which acts as a selectively permeable membrane.
(iii) If the cell had been placed in distilled water instead of strong sugar solution which feature would not have been present?
(iv) If the cell in the diagram possessed chloroplasts where would these be present?
(v) Name any one feature of this plant cell which is not present in animal cells.

Answer 1

(i) The cell is in the shrunken state or has become flaccid.

(ii) The plasma membrane acts as a selectively permeable membrane.

(iii) If the cell had been placed in distilled water instead of a strong sugar solution, then it would not have shrunk. It would have become turgid.

(iv) If the cell possessed chloroplast, it would be present in the protoplasm.

(v) A large vacuole is not present in animal cells.
