Xylem is responsible for transporting water and minerals from roots to other parts of the plant.
Ref: NCERT Class 11 Biology Chapter 6: Anatomy of Flowering Plants Meristematic and Permanent Tissues - Simple and Complex
Phloem transports organic nutrients such as sucrose. Sieve tube elements lack nuclei and function with the help of companion cells.
Ref: NCERT Class 11 Biology Chapter 6: Anatomy of Flowering Plants Meristematic and Permanent Tissues - Simple and Complex
Sieve tube elements in phloem lack nuclei and rely on companion cells for their functions.
Ref: NCERT Class 11 Biology Chapter 6: Anatomy of Flowering Plants Meristematic and Permanent Tissues - Simple and Complex
Phloem does not contain xylem vessels; instead, it consists of sieve tubes, companion cells, phloem fibers, and phloem parenchyma.
Ref: NCERT Class 11 Biology Chapter 6: Anatomy of Flowering Plants Meristematic and Permanent Tissues - Simple and Complex
Phloem is responsible for transporting organic nutrients, primarily sucrose, from source to sink in plants.
Ref: NCERT Class 11 Biology Chapter 6: Anatomy of Flowering Plants Meristematic and Permanent Tissues - Simple and Complex
Veins in a leaf provide mechanical support and act as channels for the transport of water, minerals, and food.

Answer: B) Plastids. For PSS- Sec-F-Transport, remember the key idea and you’ll land on this option; the distractors usually swap cause and effect or confuse similar terms. Avoid: A) Mitochondria; C) Peroxisomes; D) Cytosol. Name the process first, then pick the option that describes it — don’t reverse cause and effect.

That points to C: Mature leaves. Compared with the other options, Mature leaves is the one that correctly describes the PSS- Sec-F-Transport concept. The wrong ones are A) Roots; B) Developing fruits; D) Young leaves. If you’re stuck, eliminate anything that contradicts a basic fact you already know for this topic.
