Detailed explanation-1: -Solution : In dicot stem, the cells arranged in multiple layers between epidermis and pericycle constitute the cortex. It consists of three-sub-zone from outer to inner is hypodermis, cortical layer and endodermis.

Detailed explanation-2: -The cortex is a ground tissue region found in dicot stems, located between the outer epidermis and the inner vascular structures. It is primarily composed of parenchyma cells, and it may contain sclerenchyma and collenchyma cells in dicot stems.

Detailed explanation-3: -Outer hypodermis, middle endodermis and innermost general cortex.

Detailed explanation-4: -Middle cortex of dicot stem is made up of few layers of chlorenchyma cells. It is involed in photosynthesis due to the presence of chloroplast.

Detailed explanation-5: -The main function of the cortex and the pith is to transport and store nutrients and provide support. The cortex is located between the epidermis and the vascular tissue while the pith is located in the center of the stem, after the vascular bundles.
