Options:
Answer:
A
Solution:
Although some microorganisms and higher plant pollen can be freeze dried, suspension of growth in higher plant somatic tissues can be achieved only by transfer to ultra low temperatures such as that of liquid nitrogen. At these temperatures, metabolism is suspended, and free radical damage caused by ionizing background radiation is the only factor potentially causing deterioration.
