Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
How is pith and cortex ground tissue different.
A
pith is external to the vascular tissue and cortex is internal to the vascular tissue
B
Pith is internal to the vascular tissueand cortex is external to the vascular tissue
C
Pith is a vascular tissue and cortex is a ground tissue
D
Pith is in the ground and cortex is on the surface
Explanation: 

Detailed explanation-1: -The ground tissue towards the interior of the vascular tissue in a stem or root is known as pith, while the layer of tissue between the vascular tissue and the epidermis is known as the cortex.

Detailed explanation-2: -Ground Tissue: The ground tissue of a stem is divided into two regions, the cortex and the pith. The cortex is located to the outside and/or around the vascular bundles, while the pith is locate in the center of the stem. Both the cortex and pith are composed mainly of parenchyma cells.

Detailed explanation-3: -Hint: The difference between the pith and cortex is that pith is the tissue which is situated towards the vascular tissue interior to the side. Cortex is the tissue which is located between the vascular tissue layer and the epidermis.

Detailed explanation-4: -As the pith of plants is composed of parenchyma cells, it is ground tissue. Pith is present in the central portion of the stem. The cells of the pith are rounded in shape, with large intercellular spaces.

Detailed explanation-5: -Unsourced material may be challenged and removed. Pith, or medulla, is a tissue in the stems of vascular plants. Pith is composed of soft, spongy parenchyma cells, which in some cases can store starch.
