Unit 5B: Life cycles ; Section 3: Seed germination ; ... Some seeds take a long time to germinate. Radish, lettuce and spring onion seeds which germinate in 7 - 14 days can be obtained. Cress and broad beans can also be used. As the germinated seeds do not need to grow into adult plants this investigation can be carried...
