Study Notes
Root Hair Cells
- Located on the surface of plant roots, rooted hair cells enhance nutrient and water absorption.
- They develop into elongated hairs, increasing the surface area for absorption from the surrounding soil.
- Efficient absorption of water and minerals is critical for plant growth and health.
Phloem
- Specialized plant tissue responsible for the transport of food (sugars and nutrients).
- Characterized by minimal subcellular structures, facilitating the easy flow of substances.
- Phloem plays a vital role in distributing energy throughout the plant.
Xylem
- Specialized tissue designed to transport water from the roots to other parts of the plant.
- Composed of hollow structures, which allow for the unimpeded flow of water upwards.
- Essential for maintaining hydration and supporting photosynthesis within the plant.
