Solution
The correct option is D Endodermis of dicot stem
Starch sheath is endodermis of dicot stem. The endodermis is the central, innermost layer of cortex in some land plants. The endodermis is the boundary between the cortex and the stele. The endodermis helps regulate the movement of water, ions and hormones into and out of the vascular system. It may also store starch, be involved in perception of gravity and protect the plant against toxins moving into the vascular system. Thus, the correct answer is option B.
