Examine the internal organization of flowering plants, including tissues, cells, and specialized structures. This section provides a foundation for understanding how plants function and grow.
Xylem transports water and minerals, while phloem transports organic nutrients such as sucrose.

Xylem vessels are dead at maturity and function in water transport.
Ref: NCERT Class 11 Biology Chapter 6: Anatomy of Flowering Plants Secondary Growth - Dicot Stem Root and Wood
Phloem fibers are usually dead at maturity and provide mechanical strength to the plant.
Ref: NCERT Class 11 Biology Chapter 6: Anatomy of Flowering Plants Secondary Growth - Dicot Stem Root and Wood
Root hairs increase the surface area of roots for better absorption of water and minerals from the soil.
Ref: NCERT Class 11 Biology Chapter 6: Anatomy of Flowering Plants Secondary Growth - Dicot Stem Root and Wood
Tracheids are elongated cells in xylem responsible for conducting water in vascular plants.
Ref: NCERT Class 11 Biology Chapter 6: Anatomy of Flowering Plants Secondary Growth - Dicot Stem Root and Wood
Tracheids are elongated, lignified cells in xylem that provide structural support and facilitate water conduction.

Companion cells are living cells that help regulate the function of sieve tube elements in transporting organic nutrients.
Ref: NCERT Class 11 Biology Chapter 6: Anatomy of Flowering Plants Secondary Growth - Dicot Stem Root and Wood
Xylem fibers provide mechanical support, while conduction of water is performed by tracheids and vessels.
Ref: NCERT Class 11 Biology Chapter 6: Anatomy of Flowering Plants Secondary Growth - Dicot Stem Root and Wood
Phloem loading occurs via sieve tube elements and companion cells, not through xylem vessels.
Ref: NCERT Class 11 Biology Chapter 6: Anatomy of Flowering Plants Secondary Growth - Dicot Stem Root and Wood
The pericycle in dicot roots plays a crucial role in the initiation of lateral roots and secondary growth.
Ref: NCERT Class 11 Biology Chapter 6: Anatomy of Flowering Plants Secondary Growth - Dicot Stem Root and Wood
Intercalary meristem is located at the base of leaves and internodes, not at the tips of roots and shoots.
Ref: NCERT Class 11 Biology Chapter 6: Anatomy of Flowering Plants Secondary Growth - Dicot Stem Root and Wood
Xylem vessels are dead at maturity and function in conducting water and minerals from roots to other plant parts.
