Study Notes
Corn Root Structure
-
Pith: Central core of the root, plays a role in storage and sometimes transport of nutrients.
-
Epidermis: Outermost layer of cells, serves as protection and aids in water and nutrient absorption from the soil.
-
Cortex: Layer between the epidermis and vascular tissues, primarily involved in storage and transportation of materials.
-
Endodermis: Innermost layer of the cortex, acts as a selective barrier regulating the movement of water and nutrients into the vascular system.
-
Xylem: Vascular tissue responsible for transporting water and dissolved minerals from the roots to the rest of the plant.
-
Phloem: Vascular tissue that transports sugars and other metabolic products downward from the leaves.
Monocot vs Dicot Roots
-
Monocot Roots: Characterized by scattered and bundled xylem tissue, appearing disorganized when viewed under a microscope.
-
Dicot Roots: Feature an organized xylem structure typically forming an "X" shape at the center, distinguishing them clearly from monocots.
