Nervous control and Hormonal control
✓
Answer
| Nervous Control | Hormonal Control |
| The information is sent in the form of electric signals. | The information is sent in the form of chemical signals. |
| The signals travel through nerve fibres to specific target cells like muscle fibres and glands. | The signals travel through bloodstream to cells in different organs. |
| The nervous system causes muscles to contract or relax, glands to secrete more or less. But it cannot bring about growth. | Endocrine system brings about changes in metabolic activities of all body tissues. It affects growth. |
| Action is immediate (within few milliseconds). | Action is slow (can take hours or days to produce response). |
| Effect lasts for a short time. | Effect is more lasting and permanent. |

The diagram alongside refers to an experiment in which the apparatus was set up with the light source 10 cm away from the plant. After 15 minutes the number of bubbles evolved per minute from the cut stem was recorded. The light source was moved to 20 cm away from the plant, left for 15 minutes and the number of bubbles evolved per minute was again recorded. The experiment was repeated with the light source at distances of 40, 60, 80 and 100 cm away from the plant. Plot a graph for the results obtained and answer the following questions.
(i) From the graph it seems likely that the rate of bubbling per minute at 50 cm would have been
(a) 2.0 (b) 2.5 (c) 3.0 (d) 3.5
(ii) The gas produced by the plant during the experiment was
(a) air (b) oxygen (c) carbon dioxide (d) nitrogen (e) hydrogen
(iii) The gas collected comes due to the breakdown of
(a) glucose (b) starch (c) water (d) air (e) ATP
(iv) If ice cubes were added to the water, the rate of bubble formation would
(a) Stay the same.
(b) Increase because more water is added.
(c) Decrease because the temperature drops.
(d) Decrease because water freezes.
(e) Cannot tell from the information given.
(v) If some sodium bicarbonate is added to the water the rate of bubble formation
(a) Increases because more respiration occurs.
(b) Increases because more photosynthesis occurs.
(c) Increases because the gas becomes less soluble.
(d) Decreases because carbon dioxide acts as a limiting factor.
(e) Decreases because respiration decreases.
