Explain why explants cannot make their own sugars. ........................................................................................................................................... ........................................................................................................................................... ......................................................................................................................................[2] (ii) The experiment could be improved by placing the agar jelly plate with explants into a heated cabinet containing light bulbs. Describe how this cabinet could be further improved to maximise the growth and development of the explants. ........................................................................................................................................... ........................................................................................................................................... ......................................................................................................................................[2]
