Question

Cortex is the region found between
A) Endodermis and pith
B) Endodermis and vascular bundle
C) Epidermis and stele
D) Pericycle and Endodermis

Answer 1

Hint:In plants, the cortex is a tissue containing unspecialized cells that lies amidst the epidermis and the vascular tissue of roots and stems.

Complete answer:
 The cells contained within the cortex secretes carbohydrates or other related substances such as latex, resins, tannins, and essential oils.
>Option A:- The endodermis is the region present between the cortex and stele. In most of the seedless plants, endodermis is a distinct cellular layer lying immediately outside the vascular cylinder of roots and shoots.
Pith is defined as the tissue of vascular plants. Therefore, this is the incorrect option.
>Option B:- The endodermis is the region present between the cortex and stele. The vascular bundle is known to develop from the procambium region of the growing stem. Therefore, this is the incorrect option.
>Option C:- The epidermis is known as a thin layer of the skin surface. This is called the most superficial layer you get to see when you look at your skin from any point. Therefore, this is the correct option.
>Option D:-The pericycle is defined as a unique layer of plant cells named after its position which encircles the vascular tissues both in roots and stems.
The endodermis is the region present between the cortex and stele.Therefore, this is the incorrect option.

Thus, the correct option is (C) Epidermis and stele.

Note:Cortex comprises large thin walled parenchyma cells composed of the ground tissue system showing little to no differentiation in their structure. The layer of cortex cells constitutes a cork.
