explain the structure of starch and how it relates to its function
it is insoluble and therefore does nit affect the water potential of a cell- so water isn't drawn in via osmosis
it is large and insoluble so it doesn't diffuse out of cells
it is compact so a lot can be stored in a small space
when hydrolysed it forms alpha glucose which is both easily transported and readily used in respiration
amylopectin is branched so it can be easily hydrolysed
