The endodermis is responsible for storing starch as ...
Roots are specialized for the uptake of water, nutrients (including ions for proper function). [12] Similar to the endodermis, the exodermis contains very compact cells and is surrounded by a Casparian band, two features which are used to restrict the flow of water to a symplastic fashion (through the cytoplasm) rather than apoplastic fashion which (through the cell wall) flow through passages ...
