AP BIOLOGY

Detailed explanation-1: -The innermost layer of the cortex in the roots of vascular plants is the endodermis. The endodermis is responsible for storing starch as well as regulating the transport of water, ions and plant hormones.

Detailed explanation-2: -Storage roots, such as carrot, beetroot, raddish and sweet potato, are examples of roots that are specially modified for storage of starch and water.

Detailed explanation-3: -cortex, in plants, tissue of unspecialized cells lying between the epidermis (surface cells) and the vascular, or conducting, tissues of stems and roots. Cortical cells may contain stored carbohydrates or other substances such as resins, latex, essential oils, and tannins.

Detailed explanation-4: -Root cortex is made up of thin-walled parenchyma cells with inter-cellular spaces.

Detailed explanation-5: -The mass of primary tissue in roots and stems extending inward from the epidermis to the phloem. The cortex may consist of one or a combination of three major tissues: parenchyma, collenchyma and sclerenchyma.
