Definitions:

Collenchyma

A type of plant tissue that provides support, often found in areas of new growth, characterized by elongated cells with thickened cell walls.

Epidermis

The outermost layer of skin cells in animals or layer of cells in plants, serving as a protective barrier against environmental damage.

Endodermis

Internal plant root tissue forming a boundary between the cortex and the vascular cylinder.

Cortex

In plants, ground tissue bounded by the epidermis and vascular tissue in stems and roots; in animals, outer layer of an organ, such as the cortex of the kidney or adrenal gland.
