Answer 6

to check seed vitality and to grow plants to collect more seeds

Question 7

suggest how results of studies could be useful to scientists setting up seed banks

Answer 7

different plants need different storage temperatures, find optimum storage temperature for a species, temperature should be between 5°c and 20°c
