Study Notes
Aleurone Layer
- Regulates seed germination by producing enzymes that break down stored nutrients
Plasmodesmata
- Enables direct cell-to-cell communication and transport of ions, sugars, and other molecules in plants
Casparian Strip
- A specialized band of impermeable cells in root endodermis that prevents apoplastic flow of water and ions into the xylem
Nicotianamine
- A chelating agent that helps solubilize metal ions, making them available for plant uptake and transport
Potassium Deficiency
- Characterized by scorched or brown leaf edges, reduced plant growth, and increased susceptibility to disease and water stress
