Monocot Root Anatomy Quiz

Study Notes

Epidermis: The outermost layer of cells that protects the root and serves as a barrier to pathogens and water loss.
Cortex: Composed of parenchyma cells, this tissue is located between the epidermis and vascular tissue, primarily for food storage.
Pith: Located at the center of monocot roots, made up of parenchyma cells, typically involved in storage and transport.
Endodermis: A crucial single layer surrounding the vascular tissue, noted for having casparian strips that regulate water and solute movement into the vascular system.
Pericycle: A layer of tissue situated between the endodermis and the phloem; it is often a single layer thick, serving as the origin point for lateral roots.
Passage Cell: A specialized, thin-walled cell within the endodermis, facilitating the selective transport of substances into the vascular tissue.
Primary Xylem: This tissue surrounds pith parenchyma cells in monocot roots and a select few dicots, responsible for water and nutrient transport.
Primary Phloem: Located in discrete patches between xylem arms, this tissue conducts food and is integral to both monocot and dicot root structures.
