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.
Explanation
(a)
(b)(i) E: Viable seed F: Oxygen/viable seed G: Moisture/water
(ii) All the conditions of water, oxygen/air, warmth/suitable temperature, viable seed necessary for germination were present; - it is the control experiment.
(c)
