Beakers D, E, F and G contain seeds that have been sown for seven days. Carefully remove one seed/seedling from each of the beakers labelled D, E, F and place each on the corresponding white tile labelled D, E, F and G. Study them and answer questions 2(a) to 2(c). (a) Observe the soils and seed/seedling then record the observation and result on the table below.
(b)(i) Name one condition for germination that was likely absent in the beakers labelled E, F and G
E: _________ F: _________ G: _________
(ii) Give two reasons for the result in beaker D.
(c) Make a drawing 8cm to 10cm long of one sees/seedling obtained from the beaker labelled D and label fully.
(a) The observation and result table for the soils and seedlings in beakers D, E, F, and G could be as follows:
| Beaker |
Soil Observation |
Seed/Seedling Observation |
Result |
| D |
Moist, dark |
Healthy, green |
Good |
| E |
Dry |
Unhealthy, brown |
Poor |
| F |
Waterlogged |
Unhealthy, yellow |
Poor |
| G |
Sandy |
Unhealthy, withered |
Poor |
(b)(i) One condition for germination that was likely absent in the beakers labelled E, F, and G could be moisture. The soil in beaker E was dry, the soil in beaker F was waterlogged, and the soil in beaker G was sandy, all of which are not ideal conditions for seeds to germinate.
(ii) Two reasons for the good result in beaker D could be the presence of moisture in the soil and adequate sunlight, which are important conditions for germination and healthy growth of plants.
(c) A drawing of one seedling obtained from the beaker labelled D could be as follows:

In the drawing, the seedling has two small leaves, a stem, and a root. The leaves are green and healthy, indicating that the seedling is growing well. The stem is thin and has some bumps or ridges, which are normal features of plant stems. The root is also visible, and it appears to be growing downwards into the soil. Overall, the drawing shows a healthy seedling that has successfully germinated and is beginning to grow.
