Collection of the fruits or seeds, observations of their behaviour and careful examination of their structure will lead to many questions. The problem is to find a suitable organism with which to work. The plants are small but robust. They flower 14 days after sowing the seed and complete their life-cycle, from seed to seed, in only 5 weeks. There is no dormancy so another generation can be grown immediately.
Several mutants are available, but little is known of the inheritance patterns of their phenotypes.
The plants are therefore ideal for investigations in genetics. Other ideas for investigations with plants. Germinaton and growth. The seeds of many plants have two cotyledons. Investigate using thin layer chromatography.
